Charging Gel Cell Deep Cycle Batteries

Whenever you are using your deep cycle battery you have to ensure that you keep an eye on the battery s charge.

Charging gel cell deep cycle batteries.

Gel cell batteries are deep cycle batteries that contain an electrolyte which is suspended in a gel solution between lead plates. It s different from the car battery and marine battery. So it is pretty much crucial to know how to charge a deep cycle battery properly. If the incorrect battery charger is used on a gel cell battery poor performance and premature failure is certain.

At 25 c 77 f keep charging voltage in the range of 2 4 volts to 2 465 volts per cell for agm batteries. Best way to charge a deep cycle marine battery. 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. A deep cycle battery is in particular a hybrid battery.

Notice the differences in bulk absorb and float charging agm flooded and gel deep cycle 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. 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. Since gel batteries never spill they are sometimes referred to as non spillable batteries dry cell batteries or maintenance free gel batteries.

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. This is to avoid a situation where there s an unprecedented loss of power. As a rule do not equalize agm or gel batteries.

For a 12v system they do not like 15 5 v. And how long to charge a deep cycle battery. Gel batteries are best used in very deep cycle application and may last a bit longer in hot weather applications. Please set your charger to the type of chemistry your battery is.

Battery chargers with gel profile will have information either on the unit or in the manual about gel compatibility. 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. Obviously it is the advance characteristics that separate it from other even its manufacturing materials are standard and ahead of others in quality. 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.
