[quote=rcwebb;578210]Just replaced the original battery in my Tundra after it died without any warning. Started just fine when I left to go to lunch but when I came out of the restaurant, it wouldn't even turn over. Couldn't even get it to turn over with a jump. Luckily this was a certified used truck. I had to buy a battery, but not pay for the tow to the dealership. The service manager said if one cell goes dead, you can't jump the battery.

I don't understand how a dead cell in your battery would have any effect with a jump start. The battery used for the jump start completely bypasses your in-car battery. You could completely remove your battery and a jump start would work.
