QHow long does it take to charge?

A: To fully charge the battery it takes 80 minutes, or to charge it up to 80%, it takes 55 minutes.

QAre the batteries interchangeable?

A: Yes, all of the tools in the COMPACT Cordless System use the same style of battery. There are three different batteries in the range, which all have different capacities. For the FSA 56, we recommend the smaller capacity AK 10 battery as it is lighter and means the tool is perfectly balanced, but you can use the AK 20 and AK 30 battery in this tool.
