Ritar EV12-90: what it is and who it suits
If the label inside the battery box reads Ritar EV12-90, you have found the replacement. Outer dimensions are 306.5 × 168.5 × 215 mm, which should match the room inside the tray. Searching by exact code is the surest route to a matched pair.
With 90Ah, it outlasts most batteries for mobility scooters and wheelchairs on a single charge.

Installation and maintenance tips
A scooter used only once a week can lose charge between trips. Check the battery box for loose connectors every few months. A battery that looks swollen should be replaced at once.
What AGM means for you
Many glass-mat designs tolerate sideways mounting, as long as the maker says so. Low internal resistance lets AGM deliver strong bursts of current on demand. A battery tester gives a clearer picture of AGM health than a voltmeter.
Will the Ritar EV12-90 fit?
- ✓ The technology is AGM. Keep the same type as the original, and confirm your charger offers a matching profile.
- ✓ Check 306.5 × 168.5 × 215 mm against the tray, not just the old battery.
- ✓ The capacity rating, 90Ah, should suit the consumers you run. Lots of electrical equipment calls for the higher end.
