A Genuinely Surprising, Real Root Cause Worth Knowing About — Renault Kadjar Battery
If you've had two dealers and an auto-electrician all fail to find a persistent battery drain, this is genuinely worth knowing: one documented case, after three weeks of unsuccessful diagnosis, was eventually traced to a faulty immobiliser control unit itself — replacing it resolved the drain completely, with no reoccurrence six months later. This is a genuinely surprising root cause, and it's worth mentioning specifically as a possibility if you've already exhausted the usual suspects (interior lights, glovebox, boot light) without success.
It's also worth checking the glovebox door itself, not just the bulb: the plastic door can genuinely warp slightly over time, meaning the side that operates the internal switch retreats away from the switch plunger, leaving the light triggered even when the glovebox looks closed. If you've already removed the bulb and the drain persists, checking the door's fit and alignment against the switch is worth doing.
Renault Kadjar Battery: The Part Everyone Blames First, Not Always Correctly
When a Renault Kadjar won't start, the battery is the first suspect more often than anything else, and it's right often enough that checking it first is a reasonable move. It isn't always the actual cause though, which is worth knowing before paying for a replacement that solves nothing.

Renault Kadjar Battery: What It Does
Starting the engine and running electrical systems whenever the engine isn't turning — that's the Renault Kadjar's 12V battery job. If it has stop-start, it works much harder than older designs, since the engine cuts out and restarts constantly, which is exactly why it needs a specific AGM or EFB battery rather than a standard one.
