Just picked up 2 210Ah interstates at Costco for a neighbor's rig.
Says Made in usa on the sticker. 1 year free replacement.
6.34v each. 1.255 to 1.260 on all cells
84$ each before tax in Carlsbad California.
I need to borrow a bathroom scale, but I am guessing they are under 60Lbs each.
They do not look like a Deka or USbattery casing style. No obvious date coding. The caps are 'turn a lever, remove all three caps at once' style
Took 40 amps for about 25 seconds until they hit 14.8v.
Got em at 14.1v for the last few hours. Still taking 4.2 amps. Have taken 24Ah so far.
They are replacing 2 marine/rv wally world 27s that made it 2 years. New Ancor tinned copper lugs will be replacing the horror connectors it left the factory with.
edit/add.
Batteries took 40.24AH before amps at 14.7v tapered to below 1.5 amps. I kept goosing voltage briefly to 14.7 to see how many amps it took and then lowered it back to 14.1 or so.
Specific gravity never rose more than 0.005 and still reads under 1.265 on all cells and voltage goosing to 14.8v, amps now taper below 1 within 45 seconds.
So batteries are full, but the SG readings never rising depsite the batteries accepting 40AH over 24+ hours, is confusing and I will attribute it to new battery weirdness.
