Group 53 Alternatives and Closest Battery Groups by Dimensions

There are no direct interchangeable alternatives for group 53 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 53 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 53 group.

How to Get 24 Volts from 12V of a 53 Battery Group

If you need 24 Volts, you can connect two group 53 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 12V lead-acid battery is connected to another 12V lead-acid battery, you have 24V 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 53 Batteries with a Parallel Connection

If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group 53 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 12V lead-acid batteries with 60 Ah capacity and you connect them in parallel, you'll get 12 Volts with 120 Ah.
