I have a Huwawei Ascend G700-U10. It's 5 years old. It stopped working when the battery went kaput, and was abandoned for some time (I guess a year or two). I have just bought a new battery. When I connect it to a charging cable that works on other phones, the red charging light comes on, but after a second or two goes off again, and even if I leave it connected for a long time it doesn't seem to have any charge.
