Product details
Optima Redtop batteries are always ready for use and at your service. In the initial starting phase, Redtop batteries deliver immense power thanks to their patented Spiracell technology. Therefore, they are ideal for applications where starting power is of the utmost priority. Commercial agricultural and construction machinery are two applications where Optima Redtop batteries have proven themselves many times over. Of course, these batteries are also perfectly suited for emergency and rescue vehicles, as well as generators and trams. Thanks to the extremely low self-discharge of the Redtop battery, you can store it for a very long time without losing its starting capability. This, in turn, can increase your productivity by extending maintenance intervals and reducing engine repair costs.
But the Optima Redtop offers more than just power to start an engine. It lasts up to three times longer and has up to 15 times better vibration resistance than other batteries. And it is spill-proof. Thanks to the Spiracell technology, this battery has the lowest internal resistance of all lead-acid batteries on the market. Additionally, it is characterized by its fast charging capability, so full power is available again after short driving cycles. Essentially, this battery is tough as nails. Its performance and longevity are qualities you can fully trust.
