Bosch S5A13 - car battery - 95A/h - 850A - AGM technology - adapted for vehicles with Start/Stop system

Just installed the Bosch S5 A13 AGM (start/stop) car battery in my BMW 430d F36 and couldn’t be happier. It’s a high-quality, top-tier battery, one of the best you can buy for this model. Starts the engine effortlessly, handles all electrical systems with ease, and delivers reliable, long-lasting performance. Plus, it came at an unbeatable price and was delivered quickly by Amazon. Highly recommended for anyone needing a serious battery upgrade.

Bosch is my ‘go to’ brand when I’m buying blind - no real knowledge of what brand is good/bad/ugly. And I don’t think I’ve ever been disappointed… This battery is huge! and heavy!! Measure, measure, and measure again - as the items descriptions (for car batteries anyways) don’t always seem to match the physical size.. just saying 👍

Very Good Price (compared to local dealers). Delivered in good condition earlier than specified date range. Battery fitted same day and car is happy again! Has been in use for approx one month in midwinter with no problems.

Don't buy. Will not replace after five months of use, response from company after sending back for testing, it could have been faulty when sent out as it was 5 months old then. I am just emailing regarding the outcome of your warranty claim. The warranty on your battery covers all faults caused by manufacturing workmanship or material. The warranty however does not cover the following Non-Manufacturing Defects like sulphation, Wear and Tear, Deep or Over Cycling, Overcharging, or undercharging, Case damage, Terminal damage, Incorrect Application, Fault Diagnosis / Installation. As the voltage is below 10.4V, a process of sulphation occurs. Sulphation is a build-up of lead sulphate crystals and this can cause loss of cranking power, longer charging times and premature battery life. Crystals can build naturally in a battery, but with regular use and charging of the battery the crystals are small enough to be broken down. However, at the point of sulphation these crystals are so big that they cannot be broken down by the battery’s natural process. This reduces the conductive area on the metal plates inside of the battery, which means there is less usable capacity. As your battery’s voltage is reading 2.94V, the battery is fully discharged, however as the battery has not been recharged sufficiently it has led the voltage to drop further to the point of sulphation. This then prevents the battery from working to its full capacity again. Unfortunately, based on these details which are stated in our terms, we are unable to replace this battery under the warranty and it is now void. However, if you require further assistance buying a replacement battery, please let us know and we would be happy to assist.

Perfect fit for my E90 M3 and loads cheaper than my local BMW dealer. Highly recommend if you need a new battery and don't want to pay dealer prices. Installation is straight forward but you will need a code reader to tell the car the battery has been replaced.

Came perfectly fine, fitted and so far working without issues!! Preciously have a 75ah varta which was down to 50% battery life but car really didn't like it. My only issue with the battery was the missing Bosch code sticker that is usually used to code in the battery to the car, managed to figure out what to put from looking at the other parts of the battery

Great value, cheapest I could find. Arrived well packaged and working perfectly. Perfect fit for my 2018 Volvo V90.

Did the measurement — everything matches the specifications, good battery.
