Battery Issue

[FiQ150db]

I'm running two atomic 5000.1's with 5 C&D Batteries (93ah maxrate ones) with 0awg all over and a 280a XS Power alternator.

Now I can say straight off my power supply isnt adequate for all day booming but for short bursts (15 odd mins) its fine. Add to that I'm in the UK and our cars are tiny compared to your guys in the states so space is always an issue.

Now my question is my batteries rest at 12.4-6 which seems very low to me ?

I have a Ctek 25000 and was wondering should I give the recondition mode a try ?

Any one got any general advice as hardly anyone runs these batteries in the UK.

The batteries are either in poor condition, or they are not getting fully charged. Those batteries should rest 12.9 to 13.1 volts fully charged. I would try disconnecting them from one-another, and putting a proper 15 amp to 25 amp automated charger on each battery individually overnight. Once you have charged each batt individually, let it sit disconnected for a 24 hour period, and measure the resting voltage. This may give you a clue if one battery in the bank is bad, or if they do not hold voltage.
