Questions and answers
Any tips for keeping a spare battery?
Yes, but all batteries self-discharge slowly. Check the voltage every few months and recharge if needed.
How big and heavy is this Fulbat battery?
At 70 × 47 × 106 mm, measure the tray or compartment carefully. Plan the lift too: 0.65 kg is heavier than it looks.
Is the Fulbat FP6-4 suitable for a 6V system?
Yes, if they are identical. Two 6V units of 4Ah in series give double the voltage; in parallel they give double the capacity at 6V.
Does my charger suit the technology of this battery?
Being a AGM battery, it needs charging voltages suited to that chemistry. Smart chargers with a selectable mode take care of this automatically.
Will the Fulbat FP6-4 fit?
- ✓ Photograph your old terminals and compare with T1.
- ✓ As a AGM battery it needs matching charge settings in the alternator, charger or solar regulator.
- ✓ Size check: 70 × 47 × 106 mm. A battery even slightly taller than the original can touch the bonnet or the seat base.

About the technology: AGM
Glass-fibre separators in an AGM battery act like blotting paper for the acid. Premium cars with lots of electronics usually come with AGM from new. Do not mix AGM and flooded batteries in one bank.
