Q 5. What is the battery support mode and when would I use it?

A. The battery support mode provides a 13.5V DC output at up to 40A to maintain the vehicle's electrical system during prolonged diagnostic checks, preventing voltage drop that could interfere with ECU diagnostics or resets.

Q 8. Are there other versions of the SPBC40 with a different output?

A. Yes. A variant is available - the SPBC30 - which is a battery support unit and charger from the same product family at a different output. Check the SPBC30 listing for its specific specification.
