Using it day to day: practical tips

Snow ploughs start in the small hours on the coldest nights of the year. Use the battery isolator when a vehicle will be parked for more than a few days. Mud packed around terminals hides corrosion.

The lead-acid technology explained

Serviceable batteries have caps for checking the acid. Starting engines is the classic job for a lead-acid battery. Store lead-acid batteries charged and recharge them every few months.

Five checks for a perfect fit

• ✓ A different chemistry from lead-acid may need system changes.
• ✓ Grab a tape measure: 349 × 175 × 236 mm is what this case needs.
• ✓ Orientation matters: positive on the right-hand side on this model. Stand facing the long side with the terminals nearest you to compare.
