I got a 5" chinese PND with li-polymer 3.7v 1250 mAh battery, which dimension is 6cm x 3,8cm x 0,4 mm
I'm planning to replace it with a higher capacity battery, what is the max capacity for the replacement ?
Can I just soldering a 3.7v 4000 mAh battery with the same dimension to replace the old one or there are some restrictions on the capacity ?
I'm not a technician, nor I know anything about soldering electronic equipment, I plan to pay a tech repair guy to do that for me xD
Thanks
