If you believe you have a defective product we are happy to exchange it within the first 7 days but it is not refundable.

A question we get asked often is: How long should a ZPower rechargeable battery last? You can expect to get about a year of good rechargeability out of a battery. Most people tend to replace them about once a year. The best answer is when you start to see a decline in how long they stay charged in the day, that may be your sign that it is time to replace them. This technology is no longer being abundantly produced and carried by manufacturers. There is no warranty on these products even though the batteries are brand new and have never been used. What we have in stock is all we will be able to dispense moving forward. When they are gone they are gone. This also means no exchanges and no refunds as the Z Power batteries will be out of stock.
