Buying the Ritar RT1245 online

4.5Ah makes it a smaller battery, good for light electrical loads.

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.
