How lead-acid batteries work and how to look after them

Some lead-acid batteries have removable caps, others are sealed for life. Trucks and tractors often rely on robust flooded batteries. Pour in only distilled water, and only once the charge has finished.

Common questions about the Fulbat FB4L-B

Is lead-acid the same as the battery I have now?

Look at the sticker on the battery you have now. If it also says lead-acid, this is a like-for-like choice. If not, check your vehicle or system can handle the change.

Is the Fulbat FB4L-B part of a wider range?

It belongs to FULBAT Motorcycle DRY. If you need a different size with the same construction, look within that range.

Can I use the Fulbat FB4L-B instead of my old battery?

The safest test is a direct comparison: same voltage, same or slightly higher capacity, same case size and the same terminal orientation. Your owner's manual usually lists the original values.

Buying the Fulbat FB4L-B online

If the code moulded into your old battery says Fulbat FB4L-B, you have found its twin. A snug fit stops the battery rattling on rough roads. Once the code and size match, the order at baterias.online takes a couple of minutes.

4.2Ah makes it a smaller battery, good for light electrical loads.

Check before ordering

✓ With 4.2Ah of capacity, hold it up to the figure on the outgoing unit or in your equipment manual.
✓ EN cranking amps of 56A. If you are unsure of your requirement, the vehicle handbook usually states it.
✓ Set your charger to lead-acid before the first charge.
