This type of charger will NOT be able to charge you a deep cycle battery, because its main purpose is to keep your battery “topped off” when it’s not being used. There are basically two types of chargers that are generally used to charge batteries: Which charger is appropriate for a deep cycle battery?

Let it rest (cool off period) after charging.“Using incorrect charger or charging method may shorten the lifespan of your batteries.”ĭo NOT get a charger that is suitable for a car battery, you need the one that will charge the deep cycle battery correctly! Here is a plan to follow in order to ensure that your battery will be charged properly:

The closer the battery charge gets to its full capacity, the fewer amps will be supplied to it by a charger. If you go with low cost, “no-name manufacturer”, you may end up with a problem on your hands like overcharging and overheating.īattery charging from a reputable manufacturer will take place in stages. The slower the deep cycle battery will be charged, the better. The reason behind charging a deep cycle battery in phases and NOT continually at a high amp level is that you do not want to overcharge it and generate heat along the way (which is bad for the battery itself and could be a fire hazard). They are designed to give you a quick energy boost in order to start your engine, in comparison to deep cycle batteries which provide low to moderate current to run your appliances for quite a while. Regular cranking batteries are NOT designed to run anything else on your boat or RV (like a refrigerator or A/C, for example). Cranking or starting batteries have one primary purpose – “to turn on your car or boat’s motor” and they do not discharge to the level of deep cycle batteries! This type of battery is very different from car cranking batteries (AKA “starting battery”) and if not charged correctly, you will not get the maximum performance intended for those batteries and may end up with unexpected problems. They need to be charged in distinct phases in order to last longer and charge faster. The reason for this is that, unlike a standard battery, a deep cycle battery is designed to reach a significant depth of discharge (up to 80%).ĭeep cycle batteries are also known for providing more power for longer periods of time and the ability to withstand many deep discharging/recharging cycles. Selecting the right charger is the basis of charging your deep cycle battery correctly. FOR MORE INFORMATION, PLEASE READ MY EARNINGS DISCLAIMER.

If one 6V lead-acid battery is connected to another 6V lead-acid battery, you have 12V total power output.
MARINE SEALED 4D BATTERIES SERIES
The voltage of a series connection is equal to the sum of the voltages of all its batteries. If you need 12 Volts, you can connect two group GC2 batteries in series to double the voltage.

How to Get 12 Volts from 6V of a GC2 Battery Group Smaller batteries can have less capacity, performance, and power in comparison with GC2 group.

Please pay attention to the post terminal types and their location Closest Groups that Have Slightly Smaller Dimensions Battery Group NumberĬlosest but not Identical Size Battery Groupsīattery groups in this section below are not identical to the group GC2 battery, they can be a little bigger or smaller. Please check the battery compartment before you buy a battery from this group. These dimensions will fit you in 99% of cases when you want to use a different battery group instead of a GC2 battery since most battery compartments have a height margin and strict limitations on height and width only, which match batteries in the table below.

Similar Battery Groups With the Same Length, Width and Voltage If your battery holder can't hold the alternative battery group, you can buy a universal battery holder to fit in different types of batteries. In both cases, you must securely fasten your new battery with a battery holder. If your battery compartment cannot accommodate a larger battery, you can choose a smaller one. There are no direct interchangeable alternatives for group GC2 battery if we speak about dimensions, but if your battery space hasn't strict limits, you can choose a little bigger or smaller battery group.
