Optima RedtopHighest starting performance
Whenever starting power is a top priority, e.g. in heavy commercial agricultural and construction machinery. Does not lose its starting ability even during long periods of downtime. Perfect for emergency vehicles or generators.
Our recommendation for American vehicles if you want a sealed battery.
Features
Easy to install
Your advantage: With the right dimensions, it fits exactly in your US vehicle.
Connect quickly
Your advantage: Can be easily connected to the cables of common US models with US front pole with internal thread or A-cone poleHighest
Highest starting currents.
Because this AGM battery has a particularly large reaction surface due to the tightly wound grids, it charges well and has a high cold start capability.
Your advantage: Even if you have a lot of consumers installed, which eat up the battery, it brings enough power to start.
Characteristics
- Very high starting performance. Wound pure-lead plates for larger plate surface and less plate spacing.
- Very cycle resistant. Tolerates deep discharging by power-hungry consumers when the engine is switched off.
- Good vibration resistance and durability. Pressed, wound plates protect the active material.
- For extreme conditions.
- Sealed pure-lead spiral-cell battery with electrolyte fixed in glass fibre mats (AGM).
- Compact dimensions.
- 6-volt and 12-volt versions.
- Sealed maintenance-free and leak-proof.

What is a starter battery?
A battery that is charged by the alternator and starts the vehicle. For this purpose, the starter motor requires a lot of current for a short time. In addition to the cold start capacity (CCA), which indicates how much current the battery can ideally supply, the properties of a battery influence how reliably it can provide this starting power. A battery with very good charging properties recharges more quickly, for example, which benefits vehicles in city traffic in particular. It also supplies the consumers in vehicles without an additional back-up battery or supply battery. The more electrical consumers are installed at the factory or retrofitted, the more capacity is required to supply them when the vehicle is idling or at an engine stop and still reliably restart the vehicle.
Commissioning
A battery that is not fully charged when installed will not reach its full capacity in the future and will have a significantly shortened service life.
Even factory-filled and charged batteries can lose charge during storage. We recommend that you also fully charge them before installation.
You can find out how to do this in our step-by-step guide to charging your battery.
Maintenance and Care
Absolutely maintenance-free batteries are valve-regulated lead-acid batteries or VRLA batteries (VRLA = Valve Regulated Lead-Acid) that are sealed at the factory. Here, significantly less gas is produced than in wet batteries. The gas produced remains in the circuit of the battery due to gas recombination. As a result, these batteries lose significantly less liquid. They do not need to be topped up, and it is not even possible to do so, as they cannot be opened again without damage.
