    My charger has stopped working - I'm currently in India which has no dealers - any tips for substitutes etc?

    I googled this:
    charge lithium ion battery without charger

    I know of universal chargers or methods, but I know you have to get the plus/minus terminals correct in order to prevent a fire or explosion, so anyway check it out...

    You can look at your charger to see which pins are marked + and Negative. Assuming Pin 1 is on the Left of the charger, + is pin 2 and - is on the farthest right- pin 3. The batter has slots for 6 pins. Pins 1 and 2 line up with the left most slots as you place the battery in the charger, pin 3 lines up with slots 6 of the battery.

    I've "hot-wired" a charger for a Lithium Pack before- you must be very careful to not let it overheat. That left-most pin, pin 1, tells the Leica charger when to quit. The pack is 3.7v, meaning you should use slightly higher Voltage to charge- like 4.5v or so. I would buy two of those cell-phone back-up battery chargers that themselves charge off a USB port. Get two, cut up the cord on one to bring the power out to the Leica battery. The back-up battery pack will run out before damage can occur to the Leica battery.

    Is there any chance that an Internet dealer can over-night a new charger to you?
