Costco batteries saved just in time.
I traded in a 5th wheel in early August for a new one. I had two extra batteries kinda illegally mounted in the pass through storage. I removed them for liability reasons and left 2 batteries in the...

BFL13 reports the 15.7v equalization mode on the B&D40 works well, but one might have to do it more than once.
I know lead acid batteries do not have a memory, but it certainly seems like those that have been sitting and then top charged, respond better to a mid level of depletion, followed then by a full charge.
The Screwy 31 taught me not to screw around with 15.xx for equalizing. There was one instance where what couldn't be done in 3 to 4 hours at 15.7v, took 20 minutes when bumped upto 16v.
Later on I only backed off from 16v if it took more than 6.2 amps to get the 130 AH battery up there after a full absorption charge cycle, or amps started rising without a voltage increase.
Nothing quite like spinning that desired end voltage dial and some thick copper between source and battery.
