Keep your compatible Samsung cell phone charged with this Ultralast CEL-I9500NF rechargeable battery, which delivers up to 3.8V of power. The lithium-ion battery offers overload protection to help ensure the safety of your device.
I bought this battery to replace the original battery. After charging the battery over night, it does not last a day without some recharge during the day. This new battery is no different than the one that was in the phone.
