Start with group size, CCA, and terminal layout so you do not buy the wrong battery first.
- • Verify group size, CCA, and terminal orientation.
- • Check whether your vehicle needs battery registration or a memory saver.
- • Keep the install order handy: negative off first, positive back on first.
Next step
If the symptom looks bigger than the battery
Charging and starter issues often show up next when a battery test is not the full story.
- • Use the vehicle hub to keep the exact year, make, and model context in view.

What the Pros Prefer: 2022 Land Rover Discovery Battery Replacement Workflow
Terminal safety sequence, corrosion mitigation, and bracket security.
Negative Terminal Disconnection
Shop Tip:Tuck the detached negative cable aside so it cannot spring back and accidentally touch the battery negative post while you work.
Positive Cable & Hold-Down Bracket
Shop Tip:Hold-down j-bolts and brackets corrode rapidly from acid vapors. Spray threads with penetrating oil 5 minutes prior to turning to prevent snapped studs.
Terminal & Cable End Decontamination
Shop Tip:Scrape internal cable clamp surfaces until bright shiny metal shows. Even a microscopic layer of oxidation creates high electrical resistance and false starting failure.
Terminal Installation & Anti-Corrosion Seal
Shop Tip:Install the POSITIVE terminal first, then the NEGATIVE terminal last. Snug terminals until they cannot be twisted by hand, then coat exposed lead in protector spray.
