I have recently purchased Nokia C5 handset which has BL-5CT battery. I also have a spare BL-4CT battery from an older Nokia phone. Both the batteries are 3.7 V and physically similar in size.
Only difference seems to be, BL-5CT provides 1050 mAh of power and BL-4CT provides 860 mAh.
So can I use the older BL-4CT in my Nokia C5 in an emergency situation, when the main battery BL-5CT is drained and there is no way to recharge it?
Thanks in advance!
