FAQ

How long does it take to charge a 12v deep cycle battery?
15 to 20 hours for a 5 amp charging. 5 to 6 hours for a 10 amp charging. 3 to 5 hours for a 15 amp charging.

How many years should a BMW AGM battery last?
A BMW battery will typically last three to five years.

Which batteries are better for solar applications, Gel or AGM?
AGM batteries often permit greater discharge rates than Gel batteries. On battery spec sheets, AGM battery manufacturers typically list Cold Cranking Amps (CCA) ratings. The majority of solar or UPS applications are not compatible with the CCA rating; it is only applicable to high-current motors used to start engines.

Can AGM batteries explode?
The basic truth is that an AGM battery can and will initiate a self-sustaining internal heating process (thermal runaway) under the correct circumstances, which can result in catastrophic failure with the danger of fire and explosion.

How long does it take to charge a deep cycle battery at 2 amps?
A fully discharged deep cycle battery will require 24 hours to obtain 48 amps of charge while charging at 2 amp. A 48 amp deep cycle battery can be fully charged in roughly 4.8 hours at 10 amps.

Do AGM batteries require a special charger?
A specific charger is NOT necessary for AGM batteries. But LIKE ANY OTHER BATTERY, IT WILL GET BETTER CARE FROM A QUALITY “SMART” CHARGER. A typical constant voltage charger, like the one you could get at your neighborhood auto parts store, outputs power at about 12.7 volts (some are 12.6v, and some are 12.8v).

What causes AGM batteries to fail?
AGM batteries, especially OPTIMA batteries, may eventually stop working. When a starting battery is employed in a deep cycling application, failures frequently occur. AGM batteries that appear to be damaged are frequently fine. Simply put, they are deeply discharged.

Can I charge an AGM battery with a lithium charger?
You can, indeed. However, because the resting voltage for AGM is lower than that of lithium, the lithium battery will leak into the AGM. That would take a few weeks, but the two types of batteries can be used in parallel if they are charged and utilized once a week.

How do I resuscitate a deeply discharged AGM battery?
According to Optima, there are three ways to recharge an AGM battery that is deeply drained (sub 10 volts):
