What is the difference between VARTA Blue and Black labels?

[Pereira]

The warranty periods differ. The VARTA Blue label comes with an 18-month warranty, while the Black label offers a 12-month warranty. Details are as follows: 1. Blue label features: As an upgraded version of the Black label, the VARTA Blue label naturally outperforms in performance and durability, utilizing PowerFrame grid technology for high vibration resistance and heat tolerance. 2. Authorized channels: Whether choosing the VARTA Blue or Black label, it is advisable to purchase from authorized channels. Given the prevalence of counterfeit products in the market, which not only lack quality assurance (durability) but also lack overvoltage and overcurrent protection, there are potential safety hazards during charging.
