The Power Wheels® 12V Quick Charger will not produce an output until it is plugged into a working Power Wheels® battery.The charger needs to detect a battery before it starts charging, so no voltage will be present when testing it with a volt meter.
Due to the technical nature of Power Wheels® products, some Power Wheels® parts may only be installed by our authorized service centers, therefore we’re unable to provide repair manuals or diagrams. Power Wheels® has independently owned and operated authorized service centers that carry replacement parts, batteries, and chargers in addition to repairing vehicles in or out of warranty. Our Service Center locator will assist you in finding one of our authorized service centers in your area as well as provide you website addresses for service centers that offer on-line shopping.
Battery life will vary depending on how you follow the Charging and Battery Care Instructions. It's also affected by the total number of hours the batteries are used. Average battery life is one to three years.
