To recycle a lithium-ion battery, first locate a certified battery recycling center near you using this website. Before transport, tape the battery terminals to prevent short circuits and place the battery in a non-metal container. At the recycling center, staff members will safely handle the battery according to environmental and safety regulations. Some centers may offer incentives, but proper recycling is the primary goal to prevent fires and environmental damage.
The reason why you should recycle is because toxic fumes will spread if not disposed correctly. In addition to that, if it is recharged irresponsibly, it could overheat or start thermal runway, causing explosions and fire. To prevent this from happening, you can follow the battery manufacturer's instructions, unplug devices once fully charged, keep batteries in cool locations, keeping them away from flammable substances, and replace them once swollen, damaged, or unusually hot.
Get the tools you would need to salvage: LiPo charger, C4 charger, 4S battery management, Pry tools, Flush cutters, Side cutters, Utility knife, screwdrivers. After you have gotten these materials, start by taking the batteries out. Research the battery type. Then, use the LiPo charger and insert the battery. Sit back while the battery revives using the charger. Wear a mask and gloves in case the battery explodes or you get cut. ⚠️If your battery runs out of power and you can't recharge it, you can salvage it. However, salvage safely and responsibly. Also, don't recharge batteries for an excessive amount of time. Otherwise, it will overheat and catch on fire.⚠️
