Here’s one for the battery experts out there:
If I have a lithium-ion battery-powered device, which I only use infrequently, will it diminish its battery life much to always leave it in the charger?
Here’s the specifics:
I recently bought a Garmin Nuvi 250 GPS (Thanks
Green - it’s awesome!) I pretty much only ever use it when I travel (and then, mostly, in a car, where it runs off the lighter adapter). But once in a while, very infrequently, I use it when walking or cycling, which means it runs off batteries.
Part of me thinks: Okay. Just leave it plugged into a charger all the time, so that on those off occasions I want it, I can use it. Part of me wonders if I’m squandering the health of the battery by doing this. My understanding is that all rechargeable batteries lose their zip through multiple recharging. How much zip am I taking away by leaving this thing in its charger?
