A Genuinely Useful Technical Explanation Worth Knowing Before Worrying — Dacia Logan MCV Battery
If you've measured your battery voltage and found it reading around 12.5V while the engine is running, this isn't automatically a fault: the smart, regenerative alternator on later models only provides a full charge when the battery monitoring system genuinely detects it's needed, rather than constantly charging regardless of state. Switching on a load like the headlights and seeing the voltage jump up to around 14.4V confirms the alternator is working correctly and simply wasn't providing unnecessary charge a moment before.
It's also worth knowing that a documented keyless entry system recall has been suspected by some owners as a contributing cause of subsequent battery drain — if your car has had this recall work completed and you're now experiencing a new drain issue, it's worth mentioning this timing directly to whoever is investigating.
Dacia Logan MCV Battery: The Part Everyone Blames First, Not Always Correctly
When a Dacia Logan MCV 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.

Dacia Logan MCV Battery: What It Does
Starting the engine and running electrical systems whenever the engine isn't turning — that's the Dacia Logan MCV'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.
