Most of these record for less than an hour. I charged my new T189s for 3 hours and set them to record overnight, then connected them to the computer the next morning. The files show it only recorded 45 minutes or so before the battery died. I tried to record again, confirming the battery is dead. According to the listing, they should record for 5+ hours. Some of these devices have a smaller 170mAh battery instead of the 850mAh battery needed to record 5+ hours. The only way to know is to open it and look at the battery. Of the 6 or 7 I have ordered, only one had the 850mAh battery, the rest had 170mAh batteries. I ordered $9/each 800mAh replacement batteries so they can record for about 5 hours.
@@gzdl37 That is obvious. Always clean and format new drives. I used 32GB cards and only 7GB were used. After installing the 800mAh batteries they recorded for 6+ hours.
Such a confusing video. How about staying with the basic charging instructions vs leading with charging and recording. Basic instructions then build to more complex ones.
