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
- are light
- can deliver plenty of power per unit size
- are tyoically larger capacity than comparable Nickel chemistry
- are not toxic.
The only two downsides I have found in EXTENSIVE use is that they do not
take kindly to being totally flattened, and they don't take kindly to
being overcharged.Plus the price, but that is now almost comparable.
That means an hour to recharge, and NEVER flatten them. Usually the
appliance circuitry will have an under voltage cutoff anyway.
With those issues in mind, they are in every other way superior to nickel.
