I'm keeping the battery from the new boat in the garage so I can put a charger on it every so often during the winter. The battery is a Nautilus Gold Marine Deep Cycle, NG-27. Yesterday I attempted to charge the battery with an automatic charger set at 2 amps, 12 volt, deep cycle setting. The little green light began blinking as though all was going well. About 24 hours later, I noticed the little red light had come on, indicating I should check the battery. I disconnected everything. I'm thinking that 2 amps is not enough to charge the battery, and that I should try it at 10 amps. But, I don't want to damage a brand new, never used battery! Ideas anyone? An inexpensive "trickle" charger can do more damage than good. You really want to charge the battery with a smart charger, that will turn itself on and off as needed. |

No, mine's an older version of this one: http://tinyurl.com/24e7r7 It's a 125/15/2 fully automatic. I said 10 amps earlier, but the actual is 15. |

I'm thinking of something like this: http://tinyurl.com/2nbjqy But, I don't see anything there about '3 stage smart charger'. A true 3 stage smart charger automatically follows an ideal charge profile for a battery. The first stage is a "Bulk" charge mode and the voltage is in excess of 14.5 volts. Once the battery starts building it's capacity, the charger switches to an "Absorption" mode were the voltage is dropped to below a lead acid boil over rate (14.4 volts). After an extended cycle in this mode the charger switches to a "Float mode whereby it will automatically maintain the full charge. Some smart chargers also have an automatic "De sulfate" mode whereby if it senses that the battery is not taking a charge due to the plates being sulfated, it cranks the voltage up to 15 or 16 volts for a period of time, attempting to "burn off" the sulfate from the plates. It then retries the bulk charge mode and if the battery now responds, it continues with the stages. The little smart "Maintainers" also operate in different ways. Some simply maintain a voltage below the boil over threshold. Others cycle off every once in a while, allowing the battery to naturally discharge, then kick back on to charge it back up. Eisboch |

As I said, Walmart has this one for about $75 or maybe a bit less. http://store.schumachermart.com/ssc-1000a.html I'll have one before the day is out. Thanks! (And thanks to the Fed for printing money.) |
