Riva SE blinking on charge

[Tom950]

Just tried to recharge my SE battery but when I screw it on the charger it blinks a couple times like normal but then suddenly starts flashing really fast like 5 times. Anyone ideas? Just passed my warranty period 10 days ago

My Riva blinks really fast when the charge is depleted. Sometimes it keeps blinking.....I just press the button and it stops. It blinks about 3 times when I screw it on the charger. I don't think it's an issue.
