Thank you for your inquiry.
If the lights are flashing, with or without any controllers or batteries placed on the charger, this is an indication that the charger has ceased operation.
Depending on how long you've been using the same batteries and/or how long it's been since you've used the controller/charger batteries, it may be necessary to update the batteries.
Our batteries are sealed (Ni-MH) Nickel-Metal Hydride rechargeable batteries. To maintain their life expectancy stored batteries should be charged periodically (every couple of months).
The expected life of the batteries will vary depending on use, and designed for 300 – 500 charge cycles. If the batteries are less than 2 years old and have been used less than 500 cycles, please contact Performance Designed Products for replacements. All we need is your name and address.
