Using it day to day: practical tips
Couriers on scooters start and stop all day long. Charge a new battery fully before the first ride if it has been stored. Bump starting regularly wears the clutch and hides a bad battery.
What lead-acid means for you
Some lead-acid batteries have removable caps, others are sealed for life. Trucks and tractors often rely on robust flooded batteries. Avoid deep discharges to prevent sulphation.
Make sure it fits your vehicle or equipment
- ✓ Capacity is 21.1Ah. Aim for the same figure as your old battery or slightly above, never much lower.
- ✓ Starting power: 260A to the EN standard. Match or beat the figure on your current label.
- ✓ Technology to match: lead-acid. Moving to a different chemistry may need settings changed in your system.
