I have a battery that was depleted to a point where the light would not turn on when I push the button. When I put it on either the standard charger or the quick charger the light on the charger just flashes red on and off is there anyway to get this battery to charge?
Ben, how did the battery get discharged that low? How do you know it's discharged too low and there's not something else wrong with it? If this happened while using it on an Ego tool it should be covered under warranty.
Other than manually charging the battery back up to a reasonable voltage with a power supply, I'm not sure if there's anything else you can do. Manually charging the battery may bring with it some risk and a voided warranty.
