Rechargeable Batteries Warranty

 Shenzhen 3YBS Battery Co.,Ltd. offers a  limited warranty against abnormal breakdown on rechargeable batteries for a  period from the delivery date. At Shenzhen 3YBS Battery Co.,Ltd.'s discretion,  we will repair or replace the battery if our technician tests it and determines  that the battery is in fact, defective. Please be advised that since  rechargeable batteries are consumable products, warranty coverage on  rechargeable batteries is limited to not being able to hold charges (will not  charge).


Rechargeable batteries normally have a  limited charging and discharging cycles between 400 ~ 1000 cycles depending on  the application and individual's usage pattern. The capacity (available usage  time) of rechargeable batteries reduces each time they go through the charging  and discharging cycle. Due to these reasons, when rechargeable batteries are  not able to reach their full (original) capacity, they are considered as normal  wear and tear and, therefore, are not covered under this warranty.
