Care tips for AGM batteries
Each AGM cell is packed so tightly that the plates barely move, even on a bumpy road. Low internal resistance lets AGM deliver strong bursts of current on demand. Too much voltage makes the valves vent gas that can never be replaced.

- ✓ This reference uses AGM. If your current battery has a different technology printed on it, find out why before switching.
- ✓ Measure the space available: the case takes up 530.1 × 278.6 × 244.3 mm, and a few millimetres too many can stop the hold-down from closing.
