Expert Reviews

What reviewers liked

Starts regardless of temperature/weather thanks to exceptional starting burst when engine is cranked.
Like many of their batteries, it offers exceptional power and versatility. It can be mounted in any position and has more than 15 times the vibration resistance of typical automotive batteries.
Alongside durability, you’ll find this battery is ultra-reliable as well. After all, a 100-minute reserve capacity is no joke. Parasitic drain isn’t even an issue at this point.
Optima Battery has produced this model to work in harsh and sever conditions. Therefore it should be resilient to vibration and able to kick start in extreme weather conditions.

The overall weight of this battery is what we love more because compared to others, it sheds almost 12 lbs.

This is an internal design using the structure of the fibrous medium in the battery. This structure makes the battery significantly more efficient and durable–in theory.
The excellent reserve capacity of 100 minutes also provides constant power all the time and Optima claim that this battery will last twice as long as any standard alternatives.
Optima is marketing this battery as a very durable type due to its vibration-resistance feature. According to the brand, it has twice the power of the feature in comparison to other car batteries.
The battery is also leakage and spillage proof which promotes its corrosion resistant capabilities.
