Inquiry (采购产品): battery inquiry Hi I own a GPS 201, sim card operated live tracker. Unfortunately my battery lasts only about 12-13 hours when reporting every minute. I want to know if you have any back up batteries that I can leave my GPS connected to in order for it to last longer. Info: Charging voltage: DC 4.2-5.5V/400mA (Mini USB port) Internal battery: rechargeable and replaceble 1350 mAh battery (3.7V) Please let me know what you could possibly do for me. Thanks in advance **** Hidden Message ***** Niko Goro M6L1B1 Company: Gta discount E-mail: albaniko@hotmail.com **** Hidden Message ***** albaniko@hotmail.com
