Check the specs carefully, I had a customer looking at the GBs, and the
amp hr rating was suspicious, seems like they were claiming a much a
higher AH per lb than other lead acid batteries. Also they had verbally
told the customer a higher cycle life than what was listed in the actual
warranty.
I really feel the battery industry is not doing a good job of policing
itself these days, companies are doing their own testing, without
independent confirmation.

Does anyone have any experience with the GB Industrial batteries - I have
no knowledge of them. I have a client who wants to purchase their 2-volt,
2144 amphour batteries, and their pricing is much better than anything
that I can get elsewhere. They are looking to replace an existing bank (2
strings, 48v) of equivalent batteries made by Reaco(?) (now owned by
Crown). I'm trying to decide if we should resell these to our client
(taking on the potential headache and margin, or let the client deal
directly with GB. The client is willing to go either way.
Thanks,
Howie
