Why choose Bosch car batteries?

Modern cars with a lot of features and technology built in, like start/stop systems and modern braking systems for example, need powerful batteries that deliver superior performance. Bosch batteries can provide you with the performance and power capacity your vehicle requires.

Special Bosch battery models like the Bosch car battery S5 A and S4 E can deliver more power than regular batteries, in addition to being able to survive many more charging cycles than the standard issue. Below, we’ll tell you how to spot a genuine quality Bosch battery from a counterfeit product, which is essential if you want the best buy for your budget.

Check whether your Bosch battery is genuine

To make sure you’re getting what you pay for, you need to know that the Bosch battery you’re thinking of buying is genuine. You can confirm this by checking for the Bosch Secure Code Label that’s found on all genuine Bosch products. A unique 18-digit code is listed on every Bosch battery, and the last 6 digits of that code are replicated on an accompanying hologram. Aside from the hologram check, you can also verify the entirety of the 18-digit code on Bosch’s website, which can be accessed at The code should be typed in all capital letters, without any spaces.

Take note that there are counterfeit products that can replicate the hologram, as well as the Bosch Secure Code Label. You can check the legitimacy of your battery’s hologram by holding it up to light. Genuine Bosch products will have a colourful hologram when exposed to light, while a counterfeit product will only react with a black or silver colour.
