The traders' HandyNow VAT revocation Conditions of Use under Merchant Help "provided me with a battery with the label" BCG103 ". In the item description, however, the term "BCG10E" was shown. Therefore, at first I was irritated. Relief: the battery works very well! My little quick test showed that this battery can certainly compete with the original of Lumix.
Camera: Lumix TZ10 (Firmware 1.0). Test methods: continuous HD video recording in daylight. Test result: original battery 95 minutes, BCG103 93 minutes.
