Car, Motorcycle, Marine, and Light Industrial Batteries Groups Sizes Charts

Battery Group Sizes describe the maximum battery size that one battery should have in order to fit into a battery compartment intended for a battery of that size.

Although battery group charts in detail describe the batteries regarding their size, terminal orientation, nominal voltage, and similar, there is always a certain possibility that a battery is labeled as belonging to one battery group, but in reality, it belongs to some other group - for short, always check the battery size and terminal type/orientation when looking for a new battery.

List of Battery Groups

The following cross-reference chart lists, if not all, then most of the battery groups and their sizes.

Note that the actual battery group chart also lists other information, like battery orientation and similar.

Also note that these sizes are not mandatory sizes for battery manufacturers - for short, always check the actual battery size:

Motorcycle and Powersports Batteries

Motorcycle and Powersports batteries are relatively small and compact lead-acid and lithium batteries that are designed as starting/cranking batteries and are able to crank surprisingly large internal combustion gas and diesel engines.

When looking for a new battery for your motorcycle, ATV, boat, or similar, be sure to check:

  • battery size: battery sizes are standardized, but it is highly recommended to check the actual size of your old battery and the size of the battery compartment.
  • terminal type and orientation: proper battery terminal type ensures that the new battery can be connected without the use of any terminal adapters. Also, if the battery terminals are not oriented properly, there is a good chance that the cable will not be long enough to ensure a proper connection with the new battery.
  • battery voltage and CCA: this is obvious, but just in case... The new battery must have the same voltage and the same or better Cold Cranking Amps (CCA) ratings than the old battery. Capacity itself is not that important to cranking batteries, but if the new battery capacity is better, that can be only a plus for a new battery.
  • battery chemistry: the most popular Powersports batteries are sealed lead-acid AGM and Gel-Cell batteries, although lithium batteries are becoming more and more popular due to their ultra-lightweight design. It is not recommended to change the battery chemistry (lead-acid → lithium and vice versa), but if lithium drop-in battery replacements are used, they can replace lead-acid batteries in the Powersports applications, allowing new chemistry in the new battery to be used.

Of course, there are other things to verify when getting new battery, but these are the most important ones.

The following cross-reference chart lists motorcycle and Powersports batteries labels, their sizes, voltage, and terminal orientation:

Manufacturers of the lithium starting batteries often label their products as batteries that may be used to replace several lead-acid battery sizes, and they often include foam/sponge/rubber battery spacers, allowing the user to fit smaller batteries in the larger battery compartments and to prevent the battery from moving around.

How to Charge the motorcycle and Powersports Batteries?

When the battery is used within the vehicle that features a charging system, let the vehicle keep the battery charged.

If the battery is taken out of the vehicle for whatever reason (maintenance, wintering, etc.), then:

  • lead-acid Powersports batteries should be stored in a cold and well-ventilated area and connected to the advanced lead-acid battery chargers that feature temperature compensation and separate charging modes for flooded, AGM, and Gel-Cell batteries due to their small voltage differences. Also, such battery chargers, after fully recharging the batteries, automatically switch into maintenance mode, keeping the batteries fully charged for a longer period of time.
  • lithium Powersports batteries are designed as drop-in replacements for lead-acid batteries and can be recharged by the vehicle's charging system, as long as the charging voltage is kept below 15 volts (for most models). When the lithium batteries are disconnected from the vehicle, these batteries should be kept in a cool area and charged using dedicated lithium battery chargers or with smart AGM battery chargers that feature dedicated lithium battery charging mode.

Charging currents and voltages for both lead-acid and lithium batteries should be as recommended by their manufacturers.

As mentioned several times on our site, before buying a new car/marine/industrial battery, always check the size of your battery compartment, your old battery, battery terminals, wiring, and similar, and only then consider buying a new battery.

And whatever You do, stay safe - most of these batteries are able to provide huge currents that can cause injuries or worse ...


Best Group 24 Batteries

group 24 battery mGroup 24 batteries are medium-size lead-acid and lithium batteries commonly used in deep cycle applications, including automotive, marine, light-industrial, off-the-grid, medical, security, and other similar applications.

Group 24 batteries are rarely built as starting/cranking batteries, but dual-purpose group 24 batteries can crank surprisingly large gas and diesel engines.

Group 31 Dual Purpose and Deep Cycle Batteries

odyssey 31m pc2150 w200pxGroup 31 batteries are very popular marine, automotive and industrial batteries - they are mid-size batteries offering good capacity and high starting currents at an acceptable weight.

Group 31 are mostly lead-acid batteries optimized for deep cycle or dual-purpose applications, but lithium-ion batteries are also present, especially as LiFePO4 deep-cycle batteries.
