Before you order: a quick checklist
- ✓ As a lead-acid battery it needs matching charge settings in the alternator, charger or solar regulator.
- ✓ Measure the space available: the case takes up 71 × 71 × 96 mm, and a few millimetres too many can stop the hold-down from closing.
- ✓ Plus post: positive on the right-hand side. Check yours before ordering.

Common questions about the Fulbat 6N4-2A
Which way round are the posts on this battery?
The layout is positive on the right-hand side. Check the original before ordering, because the same case size is often sold in both orientations.
Does my charger suit the technology of this battery?
Being a lead-acid battery, it needs charging voltages suited to that chemistry. Smart chargers with a selectable mode take care of this automatically.
Are there other sizes in the same series?
Yes, FULBAT Motorcycle DRY includes other sizes. The brand page lists them.
How do I check compatibility quickly?
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.
About the technology: lead-acid
Plates made of lead and lead dioxide react with the acid. Lead-acid suits motorcycles and quads where simplicity and value count. Store lead-acid batteries charged and recharge them every few months.
Same case, same terminal side
If you prefer another make, these fit the same space with the same terminal side.

Installation and maintenance tips
A quad on a farm sits in the shed for days, then has to start first time on a cold morning. Fill a dry-charged battery cell by cell with its own acid and let it rest before charging. A battery that needs charging after every week parked is ready for replacement.
