## Inside the TG1250: lead-acid technology

Inside, the TG1250 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.

## Tudor TG1250 vs TF1250, TG1251 and TF1420: differences

How the TG1250 compares with Tudor batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Tudor TG1250 (this one) | 125 Ah | 760 A | 349 × 175 × 285 | right | 29.5 kg |
| Tudor TF1250 | 125 Ah | 850 A | 349 × 175 × 285 | right | 31 kg |
| Tudor TG1251 | 125 Ah | 760 A | 349 × 175 × 285 | left | 29.5 kg |
| Tudor TF1420 | 142 Ah | 850 A | 349 × 175 × 290 | right | 35.1 kg |

- Tudor TF1250: the same capacity, 90 A more cranking power, the same dimensions.
- If the positive terminal of your battery is on the other side, the one you need is the Tudor TG1251 (positive terminal on the left).
- Tudor TF1420: 17 Ah more, 90 A more cranking power, a different case (349 × 175 × 290 mm).

## Equivalents and alternatives to the Tudor TG1250

- Polarity of the TG1250: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- The TG1250 needs 349 × 175 × 285 mm of space: measure it with the hold-down clamp in place.

## Frequently asked questions about the Tudor TG1250

### Tudor TG1250 or TG1251: what is the difference?

Only the polarity: the TG1250 has the positive terminal on the right and the TG1251 the positive terminal on the left. Capacity (125 Ah), cranking power and dimensions are identical.

### How much does the Tudor TG1250 weigh?

29.5 kg, with 125 Ah of capacity. For reference, the Tudor TF1250 (125 Ah) weighs 31 kg.

### Which battery is equivalent to the Tudor TG1250?
