If what you want from your hi-fi is a crystal-clear, powerful sound, then OPTIMA® YellowTop is the battery for you. Giving you up to twice the service life of conventional batteries, it won’t let you down and, in addition, can be drained and recharged more often.

The higher voltage provides increased volume, and does so even if the battery is low. Even if your vehicle spends all winter in the garage, the low rate of self-discharge guarantees that it will reliably start up again in the spring. And should things get really loud: the OPTIMA® YellowTop is fifteen times more resistant to vibration than other batteries, capable of withstanding even the strongest vibrations.

Furthermore, it’s spill-proof and can be mounted in the vehicle in almost any position – making the fitting of unconventional car audio systems an easy task
