Group GC8 Alternatives and Closest Battery Groups by Dimensions

There are no direct interchangeable alternatives for group GC8 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. If your battery compartment cannot accommodate a larger battery, you can choose a smaller one. In both cases, you must securely fasten your new battery with a battery holder. 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.

Similar Battery Groups With the Same Length, Width and Voltage

These dimensions will fit you in 99% of cases when you want to use a different battery group instead of a GC8 battery since most battery compartments have a height margin and strict limitations on height and width only, which match batteries in the table below. Please check the battery compartment before you buy a battery from this group.

How to Get 16 Volts from 8V of a GC8 Battery Group

If you need 16 Volts, you can connect two group GC8 batteries in series to double the voltage. The voltage of a series connection is equal to the sum of the voltages of all its batteries. If one 8V lead-acid battery is connected to another 8V lead-acid battery, you have 16V total power output. Each battery must be fully charged and completely isolated from the other before connecting them in series, or there will be damage to at least one of them.

Increasing a Capacity of GC8 Batteries with a Parallel Connection

If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group GC8 batteries are in parallel, their voltage is equal to the voltage of one battery, while current capacity equals to the sum of all its battery capacities. If you have two 8V lead-acid batteries with 40 Ah capacity and you connect them in parallel, you'll get 8 Volts with 80 Ah.
