## AGM technology in the WP5S-3BP

The WP5S-3BP 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.

## Check this before ordering the Long WP5S-3BP

- The WP5S-3BP needs 120 × 60 × 130 mm of space: measure it with the hold-down clamp in place.
- With 6 Ah, the WP5S-3BP replaces an original battery of that capacity or slightly less.
