Repair of main battery
It currently costs (October 2025) NOK 95,000 (incl. VAT) to repair an 85kWh battery. A warranty of 3 years/50,000 km is given on the job. The customer chooses whether it is the car's own battery that is repaired, or if a ready repaired battery is put in. For repair of own battery, the price can be adjusted after completed diagnosis. Typical price is then between 50,000 and 95,000. The work includes replacing any bad battery modules, umbrella valves, high voltage contacts, upgrading seals and performing a tightness test. Please note that the price applies for standard repair and does not cover abnormal cases, such as major short circuits in the battery, mechanical damage etc.
Preventive maintenance of the main battery
The main battery is exposed to a lot of mud and sand. This settles in the side channels, where the umbrella valves sit. The accumulation can lead to clogged valves and condensation not escaping from the battery pack. In addition, the fuse cover on the battery is checked – and replaced if necessary. The fuse cover is a weak point on the main battery, and should be replaced at 8 years of age. This is a job we can perform in 1 day. First main inspection of the main battery on Tesla S (should be performed after approx. 8 years, when Tesla's battery warranty expires): – Remove battery pack from car and remove lists where the umbrella valves sit. Replacement of all umbrella valves on the battery pack. Replacement of metal cover over battery fuse. We offer this for NOK 14,600 (incl. VAT).
