I bought a used Valence 40AH battery mainly because the manufacturer's website said that "Built-in automatic protection for over-charge, over-discharge and over-temperature conditions". I hooked it up through a volt/amp meter to a small compressor refrigerator to see how long it would run. It ran overnight and in the next morning the volt/amp meter was blank. An analog voltmeter showed 0 volts. I connected it to a 2 stage 3 amp 12 v Battery Tender charger and have run it for about 36 hours. In the first hour the voltage climbed to 3 volts and now shows 4v with the charger disconnected. The green light on the top of the battery is still blinking. Is it safe to assume that the battery is toast? Where did I go wrong?
