You might need a hazmat suit to dispose of this battery.
Lithium-ion batteries are the predominant form of rechargeable battery and are commonly found in portable electronics as well as electrified transportation (Clean Energy Institute). In fact, the average person in the U.S. owns about nine lithium battery-powered devices. And 98% of those people use those devices daily (Recycling Today).
Why lithium? Most batteries today use lithium due to its high energy density, which averages 150-250 Wh/kg (watt-hours per kilogram), and its low self-discharge rate of around 2% per month. So essentially it stores a lot of power for its weight, and holds that charge for a long time.
Lithium Ion (Li-ion): common in laptops, smartphones, tablets, power tools, and EVs. These batteries typically last 500-1,000 charge cycles or around 3-5 years under normal use.
Lithium-Polymer (Li-Po): common in drones, RC vehicles, slim phones, and wearables because of their flexibility in shapes and sizes. These batteries typically last 500-1,000 charge cycles or around 3-5 years under normal use, but are more sensitive to overcharging, deep discharging, and swelling.
Lithium Iron Phosphate (LiFePO₄): common in solar storage, e-bikes, and some EVs. These batteries typically last 1,000-3,000 cycles (8-10 years). They are much safer and more stable than standard Li-ion batteries.
There are two main reasons to recycle or responsibly dispose lithium-based batteries, though they're not mutually exclusive. The first reason is battery aging. The signs that your battery is approaching the end of its normal lifespan include:
The battery discharges much faster than it used to.
It takes much longer to charge than normal, or won't fully charge.
The device shuts down unexpectedly even when the battery indicator shows a remaining charge.
The device overheats during normal use or charging (much hotter than it would get when new).
The second reason is safety concerns. The battery changes below are important safety concerns that you should not ignore. When any of these are the case, take action!
Swelling or bulging of the device or battery pack itself.
The battery is physically damaged (punctured, dented, crushed).
The device or charger warns you of battery issues.
The battery has been exposed to water or extreme heat.
The battery is leaking fluid or has unusual smells.
There are two great reasons to dispose or recycle batteries responsibly: safety and the environment. As you'll see below, lithium can be volatile and cause fires and explosions. It's also a toxic chemical that is bad for the environment when it leeches into drinking water, harms wildlife, and the like.
The following safety guidelines may be obvious, but it's critically important to mention them, regardless. Lithium is a high energy material that can be highly volatile under the right circumstances. So with that in mind...
DO NOT throw the device or battery in household trash; this can very likely cause a household or landfill fire.
DO NOT put the device or battery in curbside recycling; this can cause a fire or explosion in the recycling truck, and these recyclers don't handle battery recycling anyway.
DO NOT burn, crush, or puncture devices or batteries; this releases toxic gases and creates a real fire risk.
DO NOT store long-term if damaged; recycle as soon as possible. The longer you wait, the more likely the battery will leak or combust.
If you have a device or battery that needs to be recycled or responsibly disposed, follow the steps below to get it right and keep everyone safe.
Discharge if possible; drain it the device or battery down to around 20-30%. Do not try to fully discharge a damaged or swollen battery — just handle it carefully.
Protect the terminals; cover exposed battery terminals with non-conductive tape (e.g., electrical or packaging/box tape). This prevents accidental short circuits, which can cause sparks or fire. Some disposal services require that the device/battery be put into a plastic bag.
Handle swelling/damage carefully; if swollen, leaking, or punctured, place the device or battery in a fireproof container (metal box, sand, or cat litter in a plastic bag), and avoid pressing on it or trying to puncture it.
Federal law and low lithium reclamation costs have made it really easy to dispose or recycle a device or battery. Options include local drop-off and mail-in services. And they typically extend to other battery types, including car batteries!
Many electronics retailers (Best Buy, Staples, Home Depot, Lowe's, Batteries Plus, etc. in the U.S.) have battery recycling bins.
These battery recycling bins are usually in the entrance or exit vestibule, or near the store's customer service desk.
Check your local waste authority for hazardous waste collection days or special drop-off sites. The EPA also provides tools for finding disposal locations (https://www.epa.gov/hw/lithium-ion-battery-recycling).
Some battery recycling services, like Call2Recycle in North America, provide prepaid shipping kits (https://www.call2recycle.org/). They will recycle the lithium safely, and properly dispose of the enclosure and other materials.
Some retailers will accept packages on behalf of battery recycling services like Call2Recycle.
Device makers like Apple, Samsung, and Dell, often accept batteries and old devices for free recycling. Some even offer store credit towards upgrading the device! Check their websites for details.

Blazor is a powerful framework from Microsoft used for building interactive web UIs with C# instead of JavaScript. A key feature of Blazor is its flexibility in how applications are hosted and run. The choice of hosting model—Server, WebAssembly, Interactive Auto, or Hybrid—depends entirely on the specific needs of the application, such as scale/performance requirements, offline capabilities, and access to native device features.
But which flavor of Blazor should you use? Well, that depends...
The Blazor Server hosting model is the easiest to set up and use. It runs your application on the server, and when a user interacts with the application, UI events are sent to the server over a real-time (SignalR) connection. The server processes these events, calculates the necessary UI changes, and sends only those small changes back to the client to update the display. This results in a very thin client and a fast initial load time, as almost no application code is downloaded to the browser.
Best reasons to use this hosting model:
In contrast, Blazor WebAssembly runs your entire application directly in the web browser using a WebAssembly-based .NET runtime. The application's C# code, its dependencies, and the .NET runtime itself, are all downloaded to the client. Once downloaded, the application executes entirely on the user's machine, enabling full offline functionality and leveraging the client's processing power for a rich, near-native user experience.
Best reasons to use this hosting model:
The Blazor interactive auto mode allows you to use both server and WebAssembly components in a single project, giving you precise control over how your app behaves.
Best reasons to use this hosting model:
Blazor hybrid is a bit different. It's not used for building web applications. It's allows web developers to use their skills to build mobile apps that run on devices at close to native speed. Microsoft Maui is the core platform, which is native and cross-platform. It normally uses XAML for coding user interfaces. When using Blazor Hybrid, however, you can also use Blazor web components alongside XAML or in place of it.
This model provides the best of both worlds: the ability to build a rich, cross-platform UI with web technologies while having full access to the native capabilities of the device, such as the file system, sensors, and notifications.
Blazor hybrid is the perfect solution for developers looking to create desktop and mobile applications that can share UI components and logic with an existing Blazor web application, or for new mobile app projects.

Planning out a long-term strategy for your web project can really pay off. We were recently reminded of that when we were asked to create a mobile app (iOS and Android) for a web-based platform we designed and built several years ago. The platform is Coursabi, a learning platform that ensures growth at each milestone for everyone on your team. You can check it out at https://coursabi.com.
Desktop view of the Coursabi dashboard.
When we created the technical strategy we knew that a mobile app was a likely roadmap item. So we chose ASP.NET Blazor as the core platform technology. It allowed us to build a web app that felt like a single page app (SPA). And it gave us several hosting models: server, WASM (WebAssembly), and hybrid mobile. The most intriguing aspect of the Blazor Hybrid model is that unlike hybrid apps of the past, there is no web server running on the mobile device. Instead, all the C# code is compiled to native .NET code, and the web view (an embedded web browser) is only used to render the user interface. So the app runs as a native mobile app!
Various mobile (phone) views.
We knew that some features of the platform would have to be altered, since the mobile app has no web server. For example, Coursabi supports the SCORM format for external learning content. And due to security restrictions, they needed a host with a trusted root certificate. So moving that out of the platform and handling the routing changes were both necessary, but totally doable.
Another benefit of a mobile app version of the platform is that in many ways it also simplifies the security model, since the app is only running on the local device, whereas a hosted app needs to manage user state, among other concerns.
Tablet view is a hybrid of desktop and mobile.
If you have an ASP.NET-based web application, you can still leverage Blazor Hybrid to turn it into a mobile app. It just needs to first be migrated into a Blazor app. I'd also recommend reviewing your web app for opportunities to make it as mobile-friendly as possible. You don't want your mobile app to look or feel like a website. But those changes not only get you a great mobile app, they also improve how your app looks and feels in a mobile web browser. So you get twice the value.

Fynydd partnered with Blue Sequoyah Technologies to build a community-driven learning platform named Coursabi, which gives learners a simple but powerful way to grow as they follow their learning journey. Their dashboard shows them progress to-date and what assignments are next. They can explore the content library for elective learning, sign documents, and complete forms. And the community gives them a way to learn from peers and content authors.
Coursabi Mission Control is where authorized users can create and organize training content like documents, forms, and courses. There are also libraries for audio and video content, as well as imported learning modules. People and learning assignments are managed here. And administrators and training managers can stay up-to-date using dashboards, reports, notifications, community activity, and so much more.

Bossier-Parish Community College campus, Bossier City, LA.
Fynydd was asked to build a hybrid iOS, Android, and web-based learning app platform for enrolled and public students at Bossier Parish Community College (BPCC) in Bossier City, Louisiana. This was a full-stack platform that included a data tier, API service with management interface, client apps (App Store, Google Play Store), and responsive website.
The goal of the project was to research the efficacy of gamification strategies with regard to testing up and testing out of courses prior to enrollment. Secondarily it provided a great way for students to study and hone their knowledge during each semester.
The platform provided various curriculum through video courses, which each had check your knowledge quizzing as students progressed. Students could earn badges as they advanced through their learning journey and also challenge each other to quiz games for additional badges and bragging rights via a leader board.

Lehigh Valley Hospital, Cedar Crest
Lehigh Valley Health Network (LVHN) is proudly part of Jefferson Health. LVHN's mission is to heal, comfort, and care for people and communities by providing advanced and compassionate health care of superior quality and value supported by education and clinical research.
Lehigh Valley Health Network (LVHN) partnered with Fynydd to build a curated, locked-down "kiosk" learning and entertainment experience for in-room patients. It would be deployed on Apple iPads and rolled out to a limited number of random patients. IT would gather analytics on usage through tracking of the patient's Internet access and in-person feedback. The goal was to try a new approach to educating patients about their care team, as well as what to expect when they go home, and a more enjoyable experience while in the hospital.
HIPAA requires that the device be completely cleared of all personal information between patients, and nurses needed a simple way to reset the devices, and keep patients from navigating into device settings, the App Store, and other areas that would create HIPAA and security concerns.
The first thing we had to do was ensure that HIPAA compliance was possible. After some research, we discovered that by using iOS "Guided Access Mode", we could keep patients in our app, even if the device was locked. We also discussed being able to write a system which would auto-wipe any browser or other history and input from the device whenever the user was taken to the "Acceptable Use Agreement" screen, asking for consent. We also created a shortcut for hospital staff to get there and a passcode so only hospital staff could initialize the app.
The app had lots of information about a patient's care team, what to expect during their stay, and what to do when they get home. They also had access to specific web resources, including a custom YouTube interface with curated LVHN videos.
During the testing phase, armatures which held the iPads were connected to the hospital beds, making it easier for patients in most any condition to use the device. There were no support calls, LVHN IT was able to get the analytics they needed, and some lucky patients got an even better experience.

The Endo Pharmaceuticals sales department needed to improve the previous year's compliance training per regulatory requirements.
The previous platform was a step in the right direction, but had some hiccups regarding availability and consequently, a timely pass rate. Reporting on the activity and results, especially during the training period, was minimal, so executives had no way to know how the training was proceeding, in case they needed to intercede early and make adjustments, or report back successes.
It was clear from their challenges that there were some real opportunities to improve the entire training process. So Endo chose Fynydd to be their technical partner. We started by addresses availability. It became clear that the primary bottleneck was with the video hosting as it was on-premises. We worked with Endo to establish a private, secure, video content delivery network (CDN) at vimeo.
The next focus was on reporting. We gathered all the requirements and created a strategy for presenting regional analytics that gave stakeholders exactly what they needed to see.
To make it all happen, we chose Umbraco CMS to speed the product to market and provide the underpinning for membership, authentication, and of course, content management. The result was stunning. Over 2,500 people were trained in 2 weeks. There was 100% availability, and most importantly a 100% pass rate. And there were less than 10 support calls.
