Batteries for handheld test gear.
BillyO:
Does anyone have experience with those rechargeable 9V lithium batteries in handheld test gear?
They seem to have up to twice the capacity (maybe false claims) of alkaline cells, much reduced chance of leakage and potentially much, much longer life.
I'd be very interested in any and all thoughts/experience.
How long do they actually last between charges, how quickly do they re-charge, what is their self-discharge rate ... ?
beanflying:
Lithium batteries in general have little self discharge so way better than Nickel chemistry.
** Need to be careful depending on the actual chemistry of the Lithium in the case of 9V nominal generally they use 2 cells so 8.4V fully charged (a bit under 8V for a lot of their capacity) but if it is a Phosphate cell then I have seen 3 x 3.2V (9.6) volts fully charged. There is as an example an issue with the 121GW meter (AA's) and these causing issues with it.
Some of them run onboard chargers and will be 1-2 hours looking at a couple of rubbery specs. 5V USB input at 1A max :-//
As you are waving a Canadian flag too Lithium batteries fall off a cliff when you get cold so factor that in too.

Yep. Try to use a photo camera that has a lithium battery at -10... It doesn't work well.

Thanks for your input.
I'm in an all modern heated home, not a igloo in Nunavut? :-DD

I've never experienced leakage from 9 Volt alkaline, 6LF22 size batteries. Yes from alkaline AA and AAA cells.
