Choose this format where its dimensions suit your battery compartment. Compare SuperMini for a smaller footprint and Underfloor for a lower-profile installation. Allow additional clearance for terminals, cables and securing hardware.
Replacing a lead-acid battery
A similar case size does not make every installation a direct drop-in replacement. Check the charger, solar controller, alternator or DC-DC charger, load current and protection against this model's requirements. This is a house-power battery, not an engine-starting battery.
What you are buying
Select the battery pack size before adding to the cart. Pack size is the number of batteries, not a pre-wired higher-voltage system. Accessories are sold separately unless the selected offer explicitly lists them. Follow the exact model's approved instructions for mounting, charging and any series or parallel connection.

Frequently asked questions
How is Group 31 different from SuperMini and Underfloor?
Group 31 is the standard-format 100Ah option. Its listed case dimensions are 332 × 172 × 217.5mm and its listed weight is 10.0kg. Compare SuperMini when floor space is limited and Underfloor when a lower case profile is needed.
Is it a direct replacement for any lead-acid battery?
A similar case size does not guarantee compatibility. Check the available space, charger, solar controller, alternator or DC-DC charger, load current and circuit protection before replacing a battery.
Does the Group 31 model heat itself in winter?
No. This Group 31 Bluetooth model does not include self-heating. Follow its charging-temperature requirements and compare the separate heated model if your installation needs heating during charging.
Is this a starter battery?
No. It is intended for compatible auxiliary or house-power applications, such as RV, marine and off-grid installations. It is not intended for engine starting.
Does buying several batteries make a higher-voltage system?
Pack size or purchase quantity describes the number of batteries, not a pre-wired system. Follow the exact model’s approved instructions for any series or parallel connection. Accessories are separate unless the selected offer explicitly includes them.
Where can I find the right manual or get help with compatibility?
Use this product’s specifications and documents section. If you need confirmation, contact support with the product model, your planned equipment and, for an existing unit, the serial number. Do not use another model’s instructions as a substitute.
