Practical advice for UPS and standby systems
A small business loses its card machine if the UPS battery fails. Note the fitting date on the case. Exit lights that fail their duration test often need new batteries.
Care tips for AGM batteries
Glass-mat batteries are sealed, with small valves that only open if pressure builds up. Leisure vehicles choose AGM when the battery lives under a seat. Over winter, a smart unit set to its AGM programme keeps a glass-mat battery healthy with no effort.
Will the Ritar FT12-90 fit?
- ✓ The technology is AGM. Keep the same type as the original, and confirm your charger offers a matching profile.
- ✓ Dimensions to compare: 563 × 114 × 188 mm. Do not forget the base ledge, which the hold-down clamp grips on many vehicles.
- ✓ Capacity is 90Ah. Aim for the same figure as your old battery or slightly above, never much lower.
