A scooter parked outside a flat all winter rarely starts first time in March. Lay a rag over the frame to avoid scratches while lifting the battery out. Topping up a sealed battery is a mistake: the caps are fitted for good.

What AGM means for you

Glass-fibre separators in an AGM battery act like blotting paper for the acid. Cold starts are easier with AGM thanks to strong current delivery. Leaving a glass-mat battery flat for weeks invites sulphation.

Before you order: a quick checklist

• ✓ This reference uses AGM. If your current battery has a different technology printed on it, find out why before switching.
• ✓ Tape measure time: 175 × 90 × 155 mm is the footprint and height of this case. Leave a little clearance for the clamp and the cable lugs.
• ✓ Note which corner the plus post occupies on your old unit. Here it is positive on the right-hand side, and crossed cables rarely reach.
