I was just informed by multiple suppliers that East Penn and Interstate have discontinued both of the 8v batteries that I have used in locomotives and boats. The East Penn numbers were 825 and 8v195. The boats I can work around and convert to 24v. The locomotives, not so much. What are other people using in their GE critters to get the 32v?

Rolls manufactures several sizes of locomotive batteries:

We have their batteries under our BLH RS4-TC locomotives and have not experienced any problems. Our last order included shipping, which is a pretty good concession given their weight.

GNB also manufactures locomotive batteries, but is just coming out of bankruptcy. We use their signal batteries and get awesome performance - the last set we replaced was in service for 21 years, and was still holding a charge, albeit at a reduced ampacity.

This one is less than 12 inches high:

US Battery lists 11-4-1 and 13-4-1 as “product equivalent” to EAST PENN: 8V195.

For our 44 tonner and SW-8 (900hp PM), We've had good results with 8V195 size batteries (980 CCA, 1170 Reserve, 20.75 x 7.25 x 10.63.

They are a little smaller than the 8V marine batteries, and doesn't have the extra space below the plates for the sulfide mud/precipitate (they are designed like an automotive battery). As we were chasing down a fuel feed issue on the SW-8, we did over 2 dozen starts without any noticeable speed change or charging needed over a summer. From what we've seen I would say they are good up to a 1200 HP motor (@64Vdc).

you can use three 12v batteries to start things like a GE 25 ton just fine. I've also used 6 12v batteries in series to start a larger locomotive. Cranking amps isn't that big a deal-for instance the loco I started has a 400 amp cranking fuse, which practically any good 12 volt car battery can easily supply. 2 downsides, one is you will loose reserve capacity...in other words, the batteries will run down sooner, but you should have plenty to start all but the most cold natured engines. The second is, the charging system voltage and the batteries nominal voltage is very similar, which means the charging system will may not charge the batteries at all, so you need to separately charge them.

I don't know if I would suggest this as a long term solution but if you are a cash strapped group with an engine that may or may not run, this should get you to the point where you can justify the purchase of a real set of locomotive batteries.
