You can expect the H7 battery to provide a Cold Cranking Amps (CCA) rating of 600-800 A, which is essential for starting engines in cold temperatures.

The Reserve Capacity of an H7 battery is typically 120-140 minutes, indicating how long it can sustain a load before needing a recharge.

Here are the key electrical specifications of an H7 battery at a glance:

If your battery compartment can accept a slightly longer H7 battery, you can choose an H7 battery instead of an H6 battery.

The H7 battery can be replaced by a group 94R battery, but not the other way around. Always check actual size, terminal type and orientation, battery type and chemistry, and its capacity and starting performances.

H7 batteries may be replaced by H6 batteries in terms of size, but the H6 battery is "weaker" and will work harder, making it last shorter than the H7 battery.

H6 batteries have a length of 278 mm, which is 37 mm shorter than H7 batteries.

The width of H6 batteries is 175 mm, the same as H7 batteries. The height of H6 batteries is 190 mm, also matching the height of H7 batteries.

H6 batteries have equivalent sizes according to the BCI standard, including BCI Group 48 and BCI Group 98R.
