Mostly the title. I have a few items with built in rechargeable batteries that I don’t need to use very frequently. How do I keep the batteries in those items from going bad? Is there a preferred way to store them for a few weeks in between uses? Thanks in advance.
Li-Ion batteries are pretty ubiquitous anymore, the majority of devices use them. There’s still some that use NiMH. You should be able to look up specs or user manuals for any device to find out the type of battery it uses.
NiMH is actually a better solution as it has much longer cycle life and shelf life. Plus NiMH batteries don’t carry the fire hazard of Li-Ion batteries (if you’re not educated about that batteryuniversity.com is the place to go for all things battery). Even so there’s a huge difference in energy density. NiMH batteries are a lot bigger for the same energy capacity. So engineers seem to be obsessed with battery size over everything else even though NiMH is a safer more robust solution.
