WHY IT MATTERS
- —Modules abort writes when voltage dips — the classic cause of interrupted sessions.
- —Ghost faults multiply below healthy voltage; the car becomes unreliable before it becomes undrivable.
- —Start-stop cars cycle hard, and short journeys never replenish the charge used.
PRACTICAL RULES
- —Connect a maintainer for any session over thirty minutes.
- —Give the car a sustained run or a proper charger weekly, not a five-minute idle.
- —Before long storage: full charge, transport mode, maintainer if available.
DURING SESSIONS
- —We monitor voltage live and pause if it trends low.
- —A session paused for charging resumes cleanly — a bricked module does not.
- —Report slow cranking early; it is cheaper than a recovery truck.
