### ES900 or ES650: which one suits me?

Compared with the ES900, the Exide ES650 has 24 Ah less and 130 A less cranking power. The ES900 cranks harder; the ES650 is only a good option if your original battery says 410 A or less. Mind the space: the ES650 measures 278 × 175 × 190 mm.

### How much does the Exide ES900 weigh?

25.5 kg, with 80 Ah of capacity. For reference, the Exide ES650 (56 Ah) weighs 20.8 kg.

### What case size is the Exide ES900?

### Which side is the positive terminal on the Exide ES900?

On the ES900, the positive terminal is on the right with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.

### Which charger does the Exide ES900 need?

A charger with a GEL mode not exceeding 14.1-14.4 V. Charging it with a conventional lead-acid profile damages it through overcharging.
