Good Batteries – So we've got 8 vehicles all using century. They've all lasted 5 years minimum. My latest is going 7 years. Family never had any problems. Used for 25 years. Thought I'd give my 2 cents. Bit confused by the negative reviews. I know people are more likely to post negative reviews if they feel they've been screwed over. My only idea for people who have problems with batteries in general is there could be something wrong with your vehicle. Faulty alternator or something else.
