I can let my 150 Ah Telecom sit for 3 or 4 months, and when I put the MegaWatt on it at 14.40V, amps will start at around 4 amps, and within 40 -50 min, I will be down to .75 to .60 amps, in 70F temps. Zapping it briefly to 14.8V makes hardly any change at all in the amps it takes, still under 1.00 amps charge rate.
It's an unusual critter, that surplus telecom battery. It does not like high amp rate withdrawal rates either, or high recharge rates. I've never seen it take over 20 to 21 amps at 14.4V. I do need to discharge it to around 50%, just to stir up the chemistry inside. Maybe just run the unit with the fridge on for 2 days and some TV at night to lose 50 or 60 amp hours, then recharge it with the MegaWatt and the Eu1000i. 2 to 3 hours of run time should do it, then bring it home for a top charge in the garage, on the grid.
