Fulbat FTX20A-BS in everyday use
A jet ski on a trailer spends months in the garage. Charge a new battery fully before the first ride if it has been stored. Bump-starting the bike every weekend is a clear sign the battery has had its day.
What AGM means for you
Glass-mat batteries are sealed, with small valves that only open if pressure builds up. Low internal resistance lets AGM deliver strong bursts of current on demand. Check the charging voltage limit printed on an AGM label.
Make sure it fits your vehicle or equipment
- ✓ A different chemistry from AGM may need system changes.
- ✓ Check 150 × 87 × 161 mm against the tray, not just the old battery.
- ✓ Before ordering, glance at your current battery: this reference is positive on the left-hand side, and your cables need to reach that corner.
