Lipo and lead acid batteries are charged using the constant voltage method not the constant current method, so as the capacity of the battery comes up, the current must be reduced to keep a constant voltage in the battery. The voltage limit of the Lipo charge rate is 4.2volts/cell. The voltage limit on for my supernova when charging 12v lead acid battery is 2.33volts/cell or 14 volts.
If your I.C.E. charger drops to only .08amps after a few mins then the battery must be very close to full charge and the charger is topping off the battery, this part could take a while to get to 100% capacity. That is why even though the charger is set at 8 amps it will take longer than an hour to charge an 8AH(8000mah) battery.
Hope this helps some.
