Heat kills batteries. In the Gulf a Range Rover battery rarely lasts more than two to three years, and when it weakens the vehicle starts throwing electrical faults long before it fails to crank. Many models also carry a second auxiliary battery that owners are unaware of.
We test both batteries and the charging system, fit the correct AGM battery with the right capacity, register it to the body control module, and reset the stored charge history so the intelligent charging system works as designed. Most replacements are done while you wait.
Battery Replacement on the Land Rover Defender
Whether it is a classic 110 or the new L663 Defender, this is the vehicle that defines the brand. We look after both, from TD5 injector looms to the very latest D300 mild hybrid and the P525 V8.
Engines we cover on this model: 2.0 Ingenium, 3.0 Ingenium P400 MHEV, 5.0 V8, 3.0 D300 diesel, classic TD5 & Puma. Production 1983 – present (L663 & classic). Faults we see most often on the Land Rover Defender include air suspension on l663 after off-road use, ingenium oil dilution on short journeys, classic td5 injector harness oil contamination, and each is diagnosed with the model-specific procedure before any parts are recommended.

Frequently asked questions
Can I fit a battery myself?
Physically yes, but without registration the car will not charge it correctly and electrical faults may appear. We recommend professional fitting.
Which battery brand do you use?
Genuine Land Rover, Varta or Bosch AGM batteries depending on availability and your preference.
Why does my Range Rover have two batteries?
The auxiliary battery supports the stop-start system and keeps electronics stable during engine restarts.
