## Q-Battery 12LS-17 vs 12LS-18 and 12LS-12 F1: differences

How the 12LS-17 compares with Q-Battery batteries of similar size and capacity:

| Model | Capacity | Dimensions (mm) | Weight |
|---|---|---|---|
| Q-Battery 12LS-17 (this one) | 17 Ah | 181 × 77 × 167 | 5.7 kg |
| Q-Battery 12LS-18 | 18 Ah | 181 × 77 × 167 | 5.7 kg |
| Q-Battery 12LS-12 F1 | 12 Ah | 151 × 98 × 95 | 3.6 kg |

- Q-Battery 12LS-18: 1 Ah more, the same dimensions.
- Q-Battery 12LS-12 F1: 5 Ah less, a different case (151 × 98 × 95 mm).

## AGM technology in the 12LS-17

The 12LS-17 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.

## Check this before ordering the Q-Battery 12LS-17

- Length, width and height of the 12LS-17: 181 × 77 × 167 mm.
- Capacity of the 12LS-17: 17 Ah; the same as your current battery or slightly more is fine.

## Frequently asked questions about the Q-Battery 12LS-17

### 12LS-17 or 12LS-18: which one suits me?

Compared with the 12LS-17, the Q-Battery 12LS-18 has 1 Ah more. With 18 Ah, the 12LS-18 runs longer between charges than the 12LS-17 (17 Ah). Both measure 181 × 77 × 167 mm, so they fit the same tray.

### How much does the Q-Battery 12LS-17 weigh?

5.7 kg, with 17 Ah of capacity. For reference, the Q-Battery 12LS-18 (18 Ah) weighs 5.7 kg.

### Which battery is equivalent to the Q-Battery 12LS-17?

Only other AGM batteries with its dimensions and polarity: Long WPS17-12, Ritar RT12180 and Long WP18-12NSHR. Neither an EFB nor a conventional battery replaces the 12LS-17.

### Which charger does the Q-Battery 12LS-17 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.
