    These batteries like to be charged slow and low voltage. Do your chargers have an AGM/Gel setting?

    Larger chargers can easily put 30+ amps to it. Sometimes a push like that for a few minutes can take it over the hump (while carefully monitoring for excessive heat). Drop over later in the week, by the time we dumped coffees down you'd know if its a go or not.

    ^ Assuming you've already tried slow / battery tender is a good choice as well.

    Yea, had it hooked up at 2amps for 24 hours came up about half,(not enough to start car) with the other chargers hooked up I'm a little over half , but it really doesn't seem to want to charge anymore ?? , like i mentioned it does get nice and warm after charging for 4-5 hours, (not hot )

    From their site.

    BLUETOP Type: D34M / D31M/ D27M

    These batteries are dual-purpose. They are designed for engine starting and deep cycling applications, as well as for use in boats with large accessory loads.

    Recommended charging information:

    Alternator:

    13.65 to 15.0 volts, no amperage limit.

    Battery Charger:

    13.8 to 15.0 volts, 10 amps maximum, approximately for six to twelve hours.

    Cyclic Applications:

    14.7 volts, no current limit as long as battery temperature remains below 125°F (51.7°C). When current falls below one amp, finish with two-amp constant current for one hour for D34M and three-amp constant current for one hour for D27M and D31M.

    Rapid Recharge:

    Maximum voltage 15.6 volts (regulated), no current limit as long as battery temperature remains below 125°F (51.7°C). Charge until current drops below one amp.

    Float Charge:

    13.2 to 13.8 volts, one amp maximum current, time indefinite (at lower voltage).

    Strictly adhere to all limits.


    Built not bought! Follow this link to my 08 GT/CS Air Lift Performance Suspension Install Thread or this link to my Garage Thread

    My biggest fear is when I die my wife will sell my car and parts for what I told her they cost!
