Hi All,
Question:
Will a sulfated 12V Lead-Acid battery charge up to 16.2V?
Observations:
I have a 7 circuit SG hooked-up to a cap dump circuit. The output of which pulses about 1.5 Amps every 500ms to the charge battery.
I have a few 12v B.B. Battery VRLA Rechargeable 7.2 Ah batteries kicking around (not new by any means). The first one started at 13.04V (took it right out of a conventional charger) and charged to 16.13V in about 2.5 hrs.
I tried a second battery of same type. I had charged it up using the same conventional charger but it had been sitting for a day or so (it was sitting around 12.81V). I connected it to the cap dump circuit, verified everything was working correctly and left it over night. I expected it would be at least 16V the next morning but it was only around 13.04V.
Is this because this particular battery is sulfated preventing the chemistry from completing?
