Group GC8H Alternatives and Closest Battery Groups by Dimensions

There are no direct interchangeable alternatives for group GC8H 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 GC8H 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.

Battery Group Number	Dimensions	Shape	Volts	Cells	Post Terminal Type
Group GC8H Battery	10.375'' x 7.1875'' x 11.625'' in. 264 x 183 x 295 mm		8	4	"LPT", "UT", "LT"
Group GC8 Battery	10.375'' x 7.1875'' x 10.875'' in. 264 x 183 x 277 mm		8	4	"LPT", "HPT", "UT", "LT"

Closest but not Identical Size Battery Groups

Battery groups in this section below are not identical to the group GC8H battery, they can be a little bigger or smaller. Please pay attention to the post terminal types and their location

Closest Large Dimensions

Bigger batteries can have more capacity and power compared to GC8H batteries.

How to Get 16 Volts from 8V of a GC8H Battery Group

If you need 16 Volts, you can connect two group GC8H 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 GC8H Batteries with a Parallel Connection

If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group GC8H 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.
