The replacement battery for the Kyocera cellular phone is much better than the original battery supplied by the manufacturer. I am not sure how many times longer the charge holds, but that is just the point. On the old battery, I would have to recharge it after one day of use. Now I forget about charging until I see the battery low indicator...sometimes this lasts me for weeks. I keep the old battery charged and handy for a spare in case I let the charge get too low and need the phone, but it also charges on a mobile charging cord through the car cigarette lighter in a short period of time...so no real sweat there anyhow.

This was for my wife's cell phone, which kept dying rapidly after looking like it was charged. This new battery has been working great for quite a while now - it holds the charge well, and she is able to use her phone again. The price was great too. It was a good purchase.
