Battery Question
I just bought a brand new Exide deep cycle battery and it will not charge above 75% on my battery/trickle charger. I did leave the battery hooked up for a couple of days after I returned which did dr...

Consider this Progressive Dynamics Brochure report on how long it takes to charge up a deep cycle battery.
"Progressive Dynamics ran this test on the amount of time it took a PD9155 (55-amp) converter/charger set to three different output voltages to recharge a 125 AH (Amp Hour) battery after it was fully discharged to 10.5-volts.
14.4-VOLTS (Boost Mode) – Returned the battery to 90% of full charge in approximately 3-hours. The battery reached full charge in approximately 11 hours.
13.6-VOLTS (Normal Mode) – Required 40-hours to return the battery to 90% of full charge and 78-hours to reach full charge.
13.2-VOLTS (Storage Mode) – Required 60-hours to return the battery to 90% of full charge and 100-hours to reach full charge."
Note Progressive Dynamics is using a 55-AMP DC source for power. I regularly charge my three GP24 deep cycle batteries using a 60-AMP power source when camping off the power grid with my on-board PD9260C Converter/charger being run by a 2KW Honda Generator and get similar results.
I use this DC VOLTS VERSES STATE OF CHARGE chart when I am camping off the power grid to get me somewhat close to state of charge I want to be at..
The rule of thumb passed among alot of battery types here on the forum is around 20AMP of available DC power is needed for each battery being charged.
Just food for thought here...
