Group 4EH Alternatives and Closest Battery Groups by Dimensions

There are no direct interchangeable alternatives for group 4EH 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.

Closest but not Identical Size Battery Groups

Battery groups in this section below are not identical to the group 4EH battery, they can be a little bigger or smaller. Please pay attention to the post terminal types and their location

Closest Groups that Have Slightly Smaller Dimensions

Smaller batteries can have less capacity, performance, and power in comparison with 4EH group.

Battery Group Number	Dimensions	Shape	Volts	Cells	Post Terminal Type
Group 4EH Battery	19.3125'' x 5'' x 9.8125'' in. 491 x 127 x 249 mm		6	3	"A"
Group 3EH Battery	19.3125'' x 4.375'' x 9.8125'' in. 491 x 111 x 249 mm		6	3	"A"

How to Get 12 Volts from 6V of a 4EH Battery Group

If you need 12 Volts, you can connect two group 4EH 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 6V lead-acid battery is connected to another 6V lead-acid battery, you have 12V 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 4EH Batteries with a Parallel Connection

If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group 4EH 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 6V lead-acid batteries with 30 Ah capacity and you connect them in parallel, you'll get 6 Volts with 60 Ah.
