First time charging new batteries
I just bought a pair of Costco/Interstate 6 volt batteries. On the first two charges, they don't seem to be accepting charge as fast as I expected. They have not gone above 31 amps either time. I a...

The 1093 is temperature compensated so 15v at 40F is ok. Make sure it is set for "wet" batteries. The batteries may have been on the shelf too long before being recharged, so you need some catch-up.
Give them a shot of Equalize, where you run the charger at the 4 amp setting with the green light flashing--poke a nail into the hole to make it do that.
The charger will get them up to regular voltage (takes however long) and then switch to Equalize at 15.7v (compensated to whatever voltage) It will run at 4.1 amps for a while then taper to FUL. Once it does that, run an E a second time till it says FUL again.
Your hydrometer should now show all cells somewhere near 1.290 and the next time you do a recharge from 50%, you should get some time at constant 40 amps like you expect to see.
