Using it day to day: practical tips
A caravan that spends the winter parked on the drive often comes back in spring with a flat battery. Strap the battery down as firmly as you would the engine. Storing a bank half empty in the cold costs capacity that never comes back.
About the technology: AGM
Glass-fibre separators in an AGM battery act like blotting paper for the acid. Alarm panels and UPS units are classic homes for small AGM blocks. Leaving a glass-mat battery flat for weeks invites sulphation.
Five checks for a perfect fit
- ✓ Tape measure time: 328 × 172 × 222 mm is the footprint and height of this case. Leave a little clearance for the clamp and the cable lugs.
- ✓ Amp-hours: 106Ah. More capacity means more reserve for accessories and slower discharge when parked.
- ✓ Terminals: M8. Match them with your cable ends.
Frequently asked questions
Can I keep the Ritar RA12-100A on a shelf before fitting?
Yes, but all batteries self-discharge slowly. Check the voltage every few months and recharge if needed.
Dimensions and weight of this model?
At 328 × 172 × 222 mm, measure the tray or compartment carefully. Plan the lift too: 27.5 kg is heavier than it looks.
Is the Ritar RA12-100A suitable for a 12V system?
Nominal voltage is 12V and capacity 106Ah. Wiring two in series doubles the voltage, while parallel wiring doubles the capacity.

Being a AGM battery, it needs charging voltages suited to that chemistry. Smart chargers with a selectable mode take care of this automatically.
