Rickajho, they will be going in a new Provari not a mech, which will hopefully be arriving simultaneously. I understand the Provari has an in-built ability to test the voltage of the battery it's holding so I guess once I've worked out how to do that I can see if the new AW's are reaching low charge and require charging.
I admit to having zero experience with these types of batteries, so just wondered if there was any do's and don'ts with regard to first use hence the initial question.
