Registration and coding are different
Registration records a replacement battery where the vehicle requires it. Coding may change the supported battery type or capacity setting. The requirement depends on the vehicle and the replacement battery; it should be checked rather than assumed.
What to send before booking
Send the registration and a clear photo of the replacement battery label showing its type and capacity. Explain whether the battery is already fitted, whether its specification changed and whether warning messages are present.
What the visit covers
Battery registration or coding is part of our coding, resets and reports service, from £89 for a dedicated visit for one agreed function. Add one agreed function to another visit for +£40. Travel included in our service area. We confirm compatibility and the final price first. Battery supply and fitting are separate. We do not offer battery charging.
If the battery still goes flat
Registration is not a substitute for investigating a charging fault or electrical drain. If the new battery is also losing charge, explain that symptom so we can recommend the right diagnostic visit.
