GPS Tracking Tracker has a new extended battery pack that can be purchased by contacting us directly at (561) 279-3939. The battery pack lasts up to 4-6 weeks on a single charge and comes inside a pelican case. The new extended battery pack is smaller than the extended battery case, but a little bigger than the weatherproof pelican case. This is a middle option for the customer that thinks the extended battery case is too large, but who also wants to improve the battery life of the Micro Tracker. Contact us today to place an order. The new battery pack retails for $99.00.
