Technical specifications

Compatibility and selection

Before ordering, check the equipment voltage, available space, terminal position and that the required capacity matches the battery being replaced.

Installation, charging and maintenance

This sealed battery does not need water top-ups. Use secure connections, suitable ventilation and a regulated AGM charger to prevent overcharging.

Frequently asked questions

What applications is it suitable for?

It is suitable for boats, motorhomes, floor-cleaning machines, auxiliary power and solar-energy systems, provided that the equipment uses 12V and accepts its dimensions and capacity.

Can it be connected in series?

Yes. Connecting identical batteries in series adds their voltage while the Ah capacity remains unchanged. All batteries should be the same model, age and state of charge.

Which charger does it need?

Use a regulated charger with an AGM profile and for the total voltage of the battery bank. Do not use lithium charging profiles.
