Five checks for a perfect fit
- ✓ With F1/F2 terminals, some installations need a different clamp or adapter. Check before fitting.
- ✓ Built with AGM technology: if your vehicle or system was set up for another chemistry, check the charging settings first.
- ✓ Measure the space available: the case takes up 195 × 47 × 76 mm, and a few millimetres too many can stop the hold-down from closing.

How do I check compatibility quickly?
Read the part number on your existing battery and look up the original fitment in the manual. If either points to RT1245S, or the figures agree, it will work.
What AGM means for you
Glass-mat batteries are sealed, with small valves that only open if pressure builds up. 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.

Installation and maintenance tips
Gate motors and access systems rely on backup batteries when the mains drops. Check the UPS display after fitting new batteries. Heat is the biggest cause of early standby battery failure.
