Sick Lifeline Battery - Equalization Cure?

I have 2 lifelind 8d that make up my battery bank I have had a charger problem but that is now resolved. One battery is good with a full charge voltage of 12.8 voltage The other battery holds only 12.5v My question is will equalization help? Can a battery shop do this? The biggest load I have to test with is the bow truster and this battery still holds 12.4-12.4 volts. Has anybody had success with this?

I assume you are talking about an AGM battery. Go to the manual at the Lifeline website ( http://www.lifelinebatteries.com/manual.pdf ) where they give a discussion and instructions on equalization for their batt's. Good luck.

Equalization can't HURT them. Whether it will help, will depend on the condition of the batteries and what (if any) damage or wear is on them. If the two were installed in parallel and used in parallel...properly...there's no reason they would have different voltages unless there was some damage. If the wiring wasn't quite equal and one had cycled deeper or more often than the other...it could just be worn down more, forever.

Follow Lifeline's instructions (which are specific to their product) and see if it helps. I'm not sure I'd want a battery shop messing with my batteries, too many of the guys at them really aren't rocket scientists. Since Lifeline recommends routine equalizing, you might want to invest in the right equipment to maintain those expensive batteries in any case.

For Lifeline AGM's ... EQ instructions are to bring the batteries to a full charge normally and then go into EQ mode of 15.6V for 8 hours. Make sure battery temp does not exceed 120 degrees while EQ'ing.
