Fitting and everyday care
A week of fog in the hills tests every solar battery bank. Add temperature compensation if the batteries live in a room that swings from hot to cold. A bank that runs out earlier each evening has lost capacity.

Answers before you buy
Is AGM the same as the battery I have now?
Most smart chargers have a mode for AGM. Select it before charging; an unsuitable programme can shorten battery life.
Are the terminals of this battery standard?
Terminal type: 5, 6, 15. Compare with the posts or tabs on your current battery.
Are there other sizes in the same series?
Yes, TROJAN AGM RELIANT includes other sizes. The brand page lists them.
Before you order: a quick checklist
- ✓ These are 5, 6, 15 terminals. Photograph the old ones before ordering to compare side by side.
- ✓ A different chemistry from AGM may need system changes.
- ✓ Dimensions to compare: 296 × 176 × 358 mm. Do not forget the base ledge, which the hold-down clamp grips on many vehicles.

What AGM means for you
Many glass-mat designs tolerate sideways mounting, as long as the maker says so. Motorcycles benefit from glass-mat batteries because they tolerate lean angles and vibration. Over winter, a smart unit set to its AGM programme keeps a glass-mat battery healthy with no effort.
