Using it day to day: practical tips
Data centres replace whole strings of batteries on a schedule. Wear gloves when handling old batteries. Choosing on size alone and ignoring terminal width leads to connectors that will not fit.
AGM: how it works
Gas produced during charging recombines inside an AGM battery, so it loses almost no water. Glass-mat batteries shrug off vibration, which is why bikes and boats use them so often. Never try to open an AGM battery to add water.
Five checks for a perfect fit
- ✓ With F3 (flag) terminals, some installations need a different clamp or adapter. Check before fitting.
- ✓ This reference uses AGM. If your current battery has a different technology printed on it, find out why before switching.
- ✓ Size check: 181 × 77 × 167 mm. A battery even slightly taller than the original can touch the bonnet or the seat base.
