[RE-wrenches] Battery impedance analyzers

[Travis Creswell]

Hi Larry,

 

I’ve often wondered about them.  My local battery “superstore” (everything
from cell phone to golf carts) had been using them for the last few years to
test automotive starter batteries and deep cycles but the last time I was in
there I noticed they’d gone back to the old standby resistance/carbon pile
style testers.  I inquired and wasn’t able to get any exacts but the summary
was they were not happy with them.  I’m curious to know your findings on
both fronts.

 

Best,

Travis Creswell

Hello Wrenches,

 

Is anyone using an impedance type battery analyzer for lead acid batteries?
If so, what do you have and how has it worked out. I have seen prices from
$200 to $7500 and I'm sure there is a world of difference. 

 

I have been using a pulser circuit I built about 4 years ago to restore
nearly dead AGM batteries but I have not had any sophisticated method of
verifying before and after performance. I perform a constant current
equalization with no voltage limit and then leave the battery on the pulser
for a few weeks. This works great and I have restored and sold a few used
AGM batteries that would have gone to the recycler. Today our battery buyer
just picked up another 15,400 lb. of batteries from us. Yep, they were
mostly murdered! I would like to be able to restore more of them.

 

Kindest Regards,
