## Frequently asked questions about the Odyssey ODP-AGM78

### Can the Odyssey ODP-AGM78 be used in a car with Start-Stop?

Yes. As an AGM battery, the ODP-AGM78 handles automatic engine stop and brake energy recovery, and it can replace an EFB of the same size.

### How much does the Odyssey ODP-AGM78 weigh?

21.4 kg, with 61 Ah of capacity.

### Which side is the positive terminal on the Odyssey ODP-AGM78?

On the ODP-AGM78, the positive terminal is on the left with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.

In cars with energy management (common since 2010) it is worth registering the battery in the control unit so it adjusts charging. In older cars you just connect it.
