PRODUCT DESCRIPTION
ODYSSEY Extreme Racing 20 Battery
This battery, designed for competition, saves space and weight. In fact, it offers more energy for the same volume. Its robust construction is due to reinforced welds.
The battery can start even with only 20% of its capacity. Its residual capacity is higher and its mass efficiency is superior, at least 30%.
It can be stored unused for up to 2 years.
ATTENTION: Please read the attached operating instructions in PDF format.
To extend the life of your battery, it is essential to keep it almost fully charged, i.e., around 12.8 V. To ensure correct charging, it is imperative to use a specific charger such as C-Tek, which ensures 100% charging (even 108% on some models). A conventional charger will charge your Odyssey battery up to 80%.
Lug tightening torque: 5.9 Nm. Operating temperatures: -40°C to +60°C.
