[RE-wrenches] Trojan Batteries

[Tom at wagonmaker]

What size are the banks are are they series/paralleled across the terminals?  That can cause one or more cells to fail, generally starting on the negative terminal.  The set that failed on me was series/parallel across the terminals, old school, and the cell closest to the main negative overheated and shorted out, killing that string.  It’s why I went to buss bars.

Hello Wrenches,

I have had a number of customers with Trojan L-16s have problems lately. In some cases, I know that the batteries weren't very well cared for, but in no case were the batteries totally discharged and let get cold or sit for a long time. It doesn't seem that the batteries should have died after a couple of years. I could see diminished output and a reduced life. 

One customer who supposedly knows someone with inside information claims that Trojan started cutting corners a few years ago to be more competitive on price. 

Has anyone else seen more problems with Trojan Batteries, or heard that the company is cutting corners?

Thanks,

Drake
