## Inside the LA170: AGM technology

The LA170 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.

## What to look at before buying the LA170

- Measure the space: the LA170 takes up 513 × 223 × 223 mm.
- With 170 Ah, the LA170 replaces an original battery of that capacity or slightly less.
- Cold cranking: 1,000 A (EN), equal to or higher than the original.
