[RE-wrenches] SLA battery analyzer recommendations

[James Jarvis]

Hi Group,

I have a customer who has many hundreds of large Absolyte 2V cells in 24
volt battery banks. They would like some way to quantify the individual
cell health. Inspection time available at each site is limited and the
battery SOC will vary. These are off-grid sites and there is no outside
power sources available to do actual discharge testing and then the
required recharge. If it was absolutely essential, the customer could bring
a generator to each site and use a backup battery charger to put some
charge current into the string. But this would be less desirable. Battery
strings can be temporarily taken offline, but cells will ideally still need
to be connected in series.

What is the favorite magic box type meter for this application? Fluke is my
usual go to for portable test equipment. But they don't seem to be strong
in this area.

Thanks,
