## Exide EP900 vs EQ1000

Torn between the EP900 and another similar Exide? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Exide EP900 (this one) | 100 Ah | 800 A | 330 × 173 × 240 | left | 31.2 kg |
| Exide EQ1000 | 120 Ah | 1,225 A | 286 × 269 × 230 | – | 40 kg |

- Exide EQ1000: 20 Ah more, 425 A more cranking power, a different case (286 × 269 × 230 mm).

## AGM technology in the EP900

The EP900 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. Being sealed, the EP900 can be fitted in the boot or under a seat with no risk of spills.

## Check this before ordering the Exide EP900

- Length, width and height of the EP900: 330 × 173 × 240 mm.
- Polarity of the EP900: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Capacity of the EP900: 100 Ah; the same as your current battery or slightly more is fine.
- Cold cranking: 800 A (EN), equal to or higher than the original.
