Trojan 31-AGM: what it is and who it suits
Spotted Trojan 31-AGM on your installer's plan? That is the code to search. Deep-cycle construction lets it be drained and refilled daily. Plenty of off-grid owners compare batteries online before renewing a bank.
100Ah suits engines with modest electrical demands.
Before you order: a quick checklist
- ✓ Chemistry: AGM. Some vehicles and chargers are programmed for a specific type, so check before swapping.
- ✓ Check 341 × 173 × 233 mm against the tray, not just the old battery.
- ✓ Capacity 100Ah: equal to or a little above your old label is ideal.

Care tips for AGM batteries
Glass-mat batteries are sealed, with small valves that only open if pressure builds up. Backup systems rely on AGM because it can wait, fully charged, for years without fuss. Keep AGM batteries away from sustained heat, which shortens their life.

Fitting and everyday care
Holiday homes off the grid often sit unused for months between visits. Read the resting voltage of each battery once a month and note it down. Sitting partly charged for weeks lets sulphation take hold in lead batteries.
