## What it means that the FFT12-150 is AGM

The FFT12-150 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 FFT12-150

- The FFT12-150 needs 551 × 110 × 288 mm of space: measure it with the hold-down clamp in place.
- Your current battery should say about 157.6 Ah; a little more is also fine.
