Hello, ive been searching for a battery replacement compatibility thread because i bought a used Drivesmart 7 lmt-s that needs a new battery but i cannot find the exact model number when i search for replacements online, mostly nuvi models and other drivesmart. I obviously dont want to put the wrong battery or buy one that wont fit. From what i gather i need a plug with 3 wires and 3.7v, get a little confused when it comes to MAH and WH. Will i be safe replacing the 820mah and 3.03wh with say a 1250mah and 4.4wh or higher? Thanks for any input!
