Before you order: a quick checklist
- ✓ Capacity is 4.5Ah. Aim for the same figure as your old battery or slightly above, never much lower.
- ✓ Terminal type: F1/F2. Make sure your cable clamps or connectors suit it before fitting.
- ✓ As a AGM battery it needs matching charge settings in the alternator, charger or solar regulator.

Your questions answered
What if I do not know my battery reference?
Look for the printed code on the battery label, then search on baterias.online for the brand followed by that code, for example Ritar RT1245.
Can one person lift this battery?
It weighs 1.3 kg. Lift with your legs and keep it upright.
Can I keep the Ritar RT1245 on a shelf before fitting?
It is a good idea. All batteries lose some charge on the shelf, so a top-up before fitting helps.
What AGM means for you
Open up an AGM battery in your imagination and you would find the acid soaked into thin glass-fibre sheets squeezed against each plate. Premium cars with lots of electronics usually come with AGM from new. If the original was AGM, the replacement should be AGM too.

Using it day to day: practical tips
A remote pumping station depends on backup power during outages. Photograph the terminal type and connector positions before removing the old blocks. A UPS that reports a failed battery test needs new batteries soon.
