How do I charge my old motorola fliphone without a charger
The best way to charge the battery of your phone without a charger would be to get another phone that has the same battery size compartment like your phone. You can also use a universal charger that charges the battery alone.
You can always get one of the battery operated chargers that Duracell makes... but if you can afford that and the cost of battery replacement.... then I would just buy a charger.
take out the batter, find another phone that the battery can fit in,charge it and then from there you take the battery out put it in the flip phone and it will be charger
