I put the battery on my charger this morning and after a few minutes the charger went into desulfation mode. /forums/images/graemlins/confused.gif Here is what my manual says about it.
DESULFATION MODE: If a battery is left discharged for an extended period, it could become sulfated and not accept a normal charge. If the charger detects a sulfated batery, the charger will switch to a special mode of operation designed for such batteries. Activation of the special desulfation mode is indicated my blinking the CHARGING LED. If successful, normal charging will resume after the battery is desulfated. The CHARGING LED will then stop blikning and light continuously. Desulfation could take up to 10 hours. If desulfation fails, charging will be aborted and the CHECK (red) LED will blink.
After reading this I decided to call the place I purchased the battery from and asked if they could test it. They said they could so I took it back. They tested the battery and it came up bad. I exchanged the battery for a new one (same model). I had them test the new battery and it tested out fine. I just got back, hooked it up to my tractor and it started right up. /forums/images/graemlins/smile.gif
Thank you to everyone who replied with suggestions. I am new to the battery stuff so I learned a few thing from the replys.
Just for my information, I have a Schumacher Speed Charge Smart Battery Charger Model 1200A For 12-Volt Batteries. The charger has 3 options for types of batteries - Regular, Deep Cycle and AGM, Gell Cell. Is it OK to use the regular setting for the Optima battery or should I use the Gell Cell option? Here is what the manual says:
REGULAR: This is the type of battery usually used in cars, trucks, and motorcycles. These batteries have vent caps and are often marked "low maintenance" or "maintenance-free".
DEEP CYCLE: Deep cycle batteries are usually marked as "deep cycle" or "marine". Deep cycle batteries are usually larger than the other types.
AGM, GEL CEL: AGM and gel cell batteries have sealed cases without vent caps. Such batteries are often smaller than the other types.
Again - thanks,
Mike
