I would love for my Lumix TZ41 an original charger use but for the DMW-BCM13 Battery there is no original commodity buying. According to Panasonic should I charge the battery in the camera. The charger is supplied here with two batteries, the slightly less power than have the original. The charger will charge the batteries of these good warm. I charge the battery which the charger is hot and I make him better on a metal grid so that it is cooled from all sides. Nice that I can load my batteries in the car and so I forgive 5 Stars.
After three months, no failure, so further 5 Stars.
