Technology inside the Deka 8C11

Deka builds the 8C11 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.

The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.

Care and maintenance

On batteries with filler caps, check the electrolyte level and top up only with distilled water. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.
