Using it day to day: practical tips

A yacht on a mooring all winter needs its batteries checked before launch. Write the fitting date on each battery in the bank. Storing a bank half empty in the cold costs capacity that never comes back.

Care tips for AGM batteries

AGM stands for absorbent glass mat, a fancy name for a very tidy way of storing acid. Glass-mat batteries shrug off vibration, which is why bikes and boats use them so often. Charge an AGM battery on a programme made for AGM, not a generic setting.

Check before ordering

• ✓ Terminal type: M5. Make sure your cable clamps or connectors suit it before fitting.
• ✓ Technology to match: AGM. Moving to a different chemistry may need settings changed in your system.
• ✓ Check 181 × 77 × 167 mm against the tray, not just the old battery.
