| | Re: Charging JM1 battery in M-S1 charger
If it makes contact, it will be fine...the charger charges by sensing load and capacity on the battery, and adjusts for any battery that it charges. Charge voltage is the same for both batteries, but the MS-1 battery is higher capacity (ma). You should have no issue, if the charger fits and the battery contacts stay tightly contacted to the charger.
At least 17+ different BB's since 1999 -- too many to list...
