Q!#!amp!*!A:1. Why is your charge capacity is less than what others has offered for the same price?Dear Customer, just to take note not all batteries offered in the market has the stated mAh in the packaging. There is a limiton how much mAh can be packed in a form-fit factor. It is always best to check the reviews from other customers' feedback.2. Can I use it for cordless phone? Dear Customer, please do note that not all rechargeable batteries are suitable for all types ofcordless phone, so is ours. This is due to the normally higher cut-off voltage of the cordless phone, thus either it will appear low-batt or not working at all. However, that does not mean the batteries does not hold it charge. Just for cordless phone unique circuitry to allow user to have longer talk time or aware earlier that the battery is low, thus we would recommend to replace the same batteries that previously works well with your model of your phone. Do replace the batteries with rechargeable batteries of the same type and rating (see your user guide for the correct type).
