Bosch S4E40 - Car Battery - 65A/H - 650A - Efb Technology - Adapted for Vehicles with Start/Stop System

good value for money and reliable performance

Needed a new battery when stop start warning came up on my Mazda 3 and recharging the battery would not cure it. This was a perfect replacement at a good price. Correct size to allow the OEM battery ‘blanket’ to be refitted around the battery case, as well as having the correct recesses on the battery top to allow the various current sensors and connections to be refitted to the terminals. Everything worked perfectly after following the I-stop reset procedure and hopefully be a good few years before needing to replace it again.

Changed car battery, it is working well so far. No more warning message in the console wrt istop or car battery. Remember to follow istop initialising instructions for Mazda CX3. You may need contact cleaner and battery terminal contact grease depending your car's situation.

Excellent quality and performance. Good value.

Perfect for my Mazda 3, fitted battery and left it for two hours before starting. Then drove off and stop start worked straight away. Don't believe all you read on Google!

Bought in Feb 25, Battery was manufactured in Nov 24 in Spain. (You can find the mapping of 4,5,6th digits to production dates online). Start stop batteries should be within 1 year of production.Bought for Mazda 3 2016. Item was delivered in 2 work days, way before target date, carefully wrapped, packaged in plastic wrap in case of accidents, styrofoam every wall and boxed nicely. It came with more than half the charge and I have topped it up with the charger.Handles are pretty good for installation also as your brain struggles to grasp that something so small should not be so heavy!

No issues, does what I need it to do
