Optima

Optima Redtop batteries are ready to use immediately and are available at any time. During the initial starting phase, Redtop batteries deliver immense power thanks to patented Spiralcell technology, making them ideal for applications where starting performance is the top priority. Commercial agricultural and construction machinery are two applications where Optima Redtop batteries have proven themselves many times over. These batteries are also excellent for emergency and rescue vehicles as well as for generators and streetcars. Thanks to the extremely low self-discharge of the Redtop battery, you can store it for a long time without losing starting capability. This can enhance your productivity by extending maintenance intervals and reducing engine repair costs.

The Optima Redtop offers more than just the power to start an engine; it lasts up to three times longer and has up to 15 times better vibration resistance than other batteries. It is also spill-proof. With Spiralcell technology, this battery provides the lowest internal resistance of any lead-acid battery on the market. Additionally, it has a fast charging capability, so full power is available again after just a few short driving cycles. This battery is robust and reliable, with performance and durability you can trust.

Benefits:
- Lasts up to three times longer than other batteries.
- More power in the first 10 seconds of starting than comparable conventional lead-acid batteries.
- Consistent performance quality ensures your battery's energy during the discharge process.
- Ideal for seasonal use; can still start a vehicle after 12 months of storage at room temperature (or below) while fully charged.
- 15 times higher vibration resistance than other batteries.
- Spill-proof, flexible, and can be installed in almost any position.
