At least one was a brush/contact issue where the starter wouldn’t work if the armature was in a particular position. Similarly, an intermittent starter relay could cause the same symptom. Two weeks ago my car was dead, charged battery and car was okay for an hour but then battery died again.

How to troubleshoot Di2 battery drain issues, step by step?
Another symptom of damaged wires is having to ‘wake up’ the system before it’ll shift. While checking the electric wires, use the TL-EW02 cable plug tool to double check all connections. When in doubt, use the tool to unplug and reconnect each component.
What does it mean when your battery drains overnight?
Why the Battery Drains Overnight A slow battery drain when everything is off is called a parasitic power loss. This happens when something – a glovebox light, an amplifier, any electrical component – is pulling power from the battery when it shouldn’t.
What can drain the battery in a car?
Even while your car is off, your battery provides power to things like the clock, the radio, and the alarm system. These things shouldn’t have a major impact on your battery. What may drain a car battery when it’s off, however, are things such as interior lights, door lights, or even bad fuses.
Is it normal to have parasitic drain on battery?
Some parasitic drain is normal – your battery delivers enough energy to keep things, like your clock, radio presets, and security alarm operational at all times. However, if there’s an electrical problem – such as faulty wiring, poor installation, and defective fuses – parasitic drain can exceed what’s normal and deplete the battery.

What causes a battery to go bad after a long time?
But if the battery has been dry for a long time, it can cause a problem. When the plates in the cells are exposed to oxygen, it rapidly causes sulfation to build up. Sulfation is the number 1 cause of early battery failure. Plus, charging a dry battery will burn it up.
Why did my Nissan Micra battery go flat?
I used to own a Nissan Micra, and the battery was wiped out due to a similar accidental leaving of keys in the car with the lights on. The Micra’s battery was never the same after that – already not brilliant at holding charge, leaving it to go flat was the nail in the coffin that killed it.
What to do if your car battery won’t start?
Even if an ammeter (current-measuring device) says the battery is good, it can still be a few volts shy of what your vehicle needs to run efficiently. When you find yourself with a car that won’t crank hard enough to start, you’ll want to use jumper cables or a jump-starter box to get it running again.
