Doesn't quite answer the question but Li-Ion is a poor battery
technology to use in a power tool. Whether or not you use them much
your new batteries will be fairly shagged within a few years.
Hmm.
Li-ion
- don't self discharge. Typically 90% charge retention over 6 minths
Do degrade - increase in effective series resistance, and capacity over
time, especially if kept at full charge.
A lot less than nickel.
Typcially several years.
Keep in fridge if not in use.
********.
