These can replace the original lead acid batteries supplied however you cannot mix Lithium batteries with Lead acid so always replace both batteries at the same time.  These are easily changed by the user and do not need to be returned to Edwards for changing.

** These batteries may also work in the Challenger 1000, but those DO have to be changed by a service centre as they have to be disassembled to make the change.
