Best batteries for Fluke 189, 287 and 289
(1/6) > >>
BeBuLamar:
I have the 189, 287 and 289 and they all take AA batteries. As you know alkalines leak so which is better to use in these meter NiMH or Li-Ion AA rechargeables? The Li-Ion has somewhat less capacity but has a rather constant 1.5V throughout the discharge cycle but is this of any advantage to a DMM? Also I am not sure if Li-Ion would have a lower or higher self discharge rate compared to good NiMH like the Eneloop?
coppercone2:
lol the 289 chew through batteries I think NiMH is the way to go but the low battery alarm trips out because the cell voltage is low. i would be pissed if I had to keep paying for lithium to run that thing.
coromonadalix:
for  187 189,  try to find the rare   BP-189 battery pack with 4x "C"   cells   you could put some rechargeable cells  etc ....
Kjelt:
I use for the 187 four Eneloops AA NiMh the last ten years.
Only have to charge them once a year but I don't use it that often.
Still the same batteries.
BeBuLamar:
My question is whether the Li-Ion AA rechargeable like these

are better or worse than the Eneloop?
I don't mean the disposable lithium.
