How long does it take to charge the Northwind Commuter 5 battery, including a quick top-up?

With the charger that comes with the bike (2 amp), a full charge from empty takes about:

• 14 Ah battery (standard): 6 to 7 hours

• 20 Ah battery: 8 to 9 hours

Quick top-ups: Charging is fastest at the start. The battery reaches about 80% in roughly two thirds of the full charge time. If you haven't run the battery down to empty, a top-up will be quicker still.

Most people charge overnight. You don't need to charge to full every time.
