I got a problem on AIPTEK IS-DV2.4 with battery power. I loaded new battery, the indicator show full charge on battery. I noted if I take video, the battery lost its power very fast to may be half power within a matter of few minutes. I usually end up changing new battery within half an hour. I believe there is some leakage somewhere but I do not know how to fix. I want to use alternative power source but there is no such feature. Where could find free software for DVTS.
