If your charger keeps resetting and beeping, it may mean your battery or batteries have a bad cell(s) and are below the normal voltage level. What happens is when these batteries set on a shelf waiting to be sold, chances are they had a charge on them. When a charge higher than the recommended storage charge is left in the battery for any extended period of time, the batteries will begin to degrade and fall below the normal/safe voltage level per cell. When this happens, you may see the battery swell or seem puffy/bloated. Also your charger will recognize the low voltage in battery cell(s) when you try to charge them and alert you. This will be the auditable beep you hear from your charger. Unfortunately there isn't much you can do except return the battery if its still possible to do so and receive a replacement. Normally you can't fix the problem of low voltage in a battery cell(s). Hope this helps.
