So far this battery has worked surprisingly well… I have left it unused in the car for weeks and it still seems to be full strength

Battery lasted barely a year and ghosted
I purchased this Bosch battery for my Land Rover because the previous Bosch battery had lasted over 8 years . Well this new Bosch barely lasted 1 year and would not take a charge. The sellers are impossible to get ahold of so will try to go through Amazon. Poor service and product but in honesty have had very few Bosch products but this exception

Well Made
You can't beat these batteries. Another company make them but who cares. My last one lasted six years while the same model car had a different battery and last two. Pay the extra money and get some dependability.
