## Frequently asked questions about the Ritar FT12-105

### Ritar FT12-105 or FT12-100A?

Compared with the FT12-105, the Ritar FT12-100A has 5 Ah less. With 105 Ah, the FT12-105 runs longer between charges than the FT12-100A (100 Ah). Both measure 508 × 111 × 236 mm, so they fit the same tray.

### How much does the Ritar FT12-105 weigh?

The FT12-105 weighs 32.5 kg. For reference, the Ritar FT12-100A (100 Ah) weighs 29 kg.

### Which battery is equivalent to the Ritar FT12-105?

Only other AGM batteries with its dimensions and polarity: Fulbat FFT12-100 and Ritar FT12-100A. Neither an EFB nor a conventional battery replaces the FT12-105.

### Which charger does the Ritar FT12-105 need?

A charger with an AGM mode that limits voltage to about 14.4-14.7 V. Never an old unregulated charger: overcharging dries out an AGM beyond repair.
