[RE-wrenches] Battery impedance analyzers

[Larry Crutcher, Starlight Solar]

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,
