This history of this relates to my previous thread, but basically I've got an 100Ah AGM that is 16months old and appears to drop a cell after it has been partially discharged (will run 8amps for an hour dropping voltage slowly through 12.55,12.5,12.45,12.4 then in a sudden crash drop to below 10v while under load, ie 5 minutes to go from 12.4 to 10v, but an hour to go from 12.55 to 12.4). I've done several tests now with help and advice from a few ExplorOz users and I'm pretty certain that the battery has failed, and I don't think it's my fault.

The battery is an Abosorbed Power brand and I purchased it through Bias Boating who had purchased through Powerdive who have now apparently gone bust/sold the battery business, I'm not sure which (bust/sold) but not selling batteries any more anyway.

I've spoken the the Absorbed Power (Orbis) guy and he told me that since he bought/took over the business from Powerdive that he can't warrant the battery and that I should speak to Bias to see what their arrangements are. I've spoken to Bias and they say that since Powerdive is no longer in business they can't handle the warranty and I need to speak straight to the manufacturer, Absorbed Power.

I don't know if there is anything that I can do, obviously I can't buy another Absorbed Power battery (although they're happy to sell me a new battery plus a new charger, yeh right, Bias seem happy to sell me a new battery too). I do have a new AGM that I had just purchased before I found out this one failed, I'm glad it's a different brand.

Anyway I figured I'd ask if anyone has any ideas on how I should proceed, currently just contemplating giving up, but maybe someone out there has a better idea for me.

As an aside, the Aborbed Power guy told me that "... the batteries need to be charged at 14.8 volts to gain 100% charge and if not 100% charged will quickly sulphate and die in around 16 months..." obviously the 16 months was tongue-in-cheek but the 14.8 (ie a high charge voltage) seems to contradict a lot of other info I've read/seen, has anyone got any ideas on this?

Thanks in advance for any ideas.
