Charging Gel Cell Deep Cycle Batteries

Battery chargers with gel profile will have information either on the unit or in the manual about gel compatibility.
Charging gel cell deep cycle batteries. It s different from the car battery and marine battery. To ensure that the battery life of the battery is maintained make sure that you charge the battery when the battery s charge level is not lower than 50. At 25 c 77 f keep charging current in the range of 2 38 volts to 2 42 volts per cell for gel cell batteries. At 25 c 77 f keep charging voltage in the range of 2 4 volts to 2 465 volts per cell for agm batteries.
For a 12v system they do not like 15 5 v. Compensation for battery temperature above or below 25 c 77 f can be made by subtracting 0 005 volts per cell for each 1 c. The best way to charge a deep cycle marine battery is to get a charger designed for the task. Whenever you are using your deep cycle battery you have to ensure that you keep an eye on the battery s charge.
Best way to charge a deep cycle marine battery. The best deep cycle battery charger should charge the battery slowly. And how long to charge a deep cycle battery. Just connect the clamps according to the directions and it s auto sensing circuitry monitors the environment and the deep cycle marine battery to provide a fast charge without damaging your battery.
This is to avoid a situation where there s an unprecedented loss of power. You really do not want a rapid charge on a deep cycle battery because during a slow charge the plates are penetrated by the battery acid but when you have a rapid charge there is not a sufficient amount of time for the battery acid to do this penetration. It s important to set it to deep cycle in order to mimic the charging characteristics of a cvc constant voltage charger the type of charger designed to charge deep cycle gel batteries. Gel batteries are best used in very deep cycle application and may last a bit longer in hot weather applications.
Notice the differences in bulk absorb and float charging agm flooded and gel deep cycle batteries. Please set your charger to the type of chemistry your battery is. A deep cycle battery is in particular a hybrid battery. Gel cell batteries are deep cycle batteries that contain an electrolyte which is suspended in a gel solution between lead plates.
As a rule do not equalize agm or gel batteries. So it is pretty much crucial to know how to charge a deep cycle battery properly. Since gel batteries never spill they are sometimes referred to as non spillable batteries dry cell batteries or maintenance free gel batteries. A typical deep cycle battery regardless of its design is designed to reach a significant depth of discharge the fraction of the battery s original capacity that is consumed through use and then be recharged to full capacity for many cycles over its lifetime.
