It looks like the battery on my generator is gone. It is about 5 years old. I purchased Schumacher charger but it was not able to revive the battery. I was not impressed with the charger. It claims the battery is good but putting a voltmeter on it during the cranking tells me that either the battery is NOT charged or it is dead. I am not sure if I should go for another charger or just get a new battery and forget about another charger. Is 5 years expected life of a sealed lead acid battery? It is 15AH 12V 3x6x7 inches. It probably had about less than 5 starts on it.
