ODYSSEY Extreme Racing 30 battery This battery intended for a use in competition allows a saving of place and weight. Indeed, it contains more energy for the same volume. Solid construction thanks to the reinforced welds. The battery allows a start even with only 20% of the capacity. Its residual capacity is greater and the mass efficiency is higher, at least 30%. Storage without use for up to 2 years.   In order for your battery to last a long time, it is imperative to keep it close to full charge, i.e. around 12.8 V. In order to ensure a correct charge, it is imperative to use a specific charger such as C-Tek which ensures a 100% charge (even 108% on certain models). A conventional charger will charge your Odyssey battery up to 80%.
