Flat Battery

[browndmb]

Have been having battery problems. A new battery and every morning have the most awful job at starting the car. Have been round to check nothing untoward All switched off and still no joy. There must be something using all the charge but cannot think where it goes.
Please help

Do you mean the battery is flat every morning.. or do you mean you just have trouble getting the car to start.
Make one model will help.. Petrol or Diesel?

Make and model.. Predictive text!

Have you got a dashcam permanently connected to the battery?

when we were in lockdown the first time, as I wasn't using my car as much, I had a little trouble starting it each day that I needed it. I did a long blast journey and it seemed to sort it out

Does the engine turn slowly or fail to turn at all? Is the car kept outside or in a garage? Is the engine oil the correct grade? Are you sure the battery connections are clean, including the ends connected to the starter motor and the one connected to the car body? How long a journey do you make once you start the car?

Is the car engine turning over in a lively manner?
If it is, the problem lies with the engine (diesel or petrol?)
Does the engine struggle to turn over?
Do you have the means of checking the battery voltage? On a cold morning, prior to starting, it should be above 12 Volts and ideally around 13 Volts.
If a cell has shorted the indicated voltage will likely be around 10 Volts and the battery will be kaput.

If its a brand new battery, go back to were you had it from, and ask them to check it out, they will tell you if the battery is faulty, or your car is not charging it, but just draining it. If all checks out ok on that front, you should be looking at coil pack / injectors/ heat plugs/ spark plugs, the latter's depends on what car you have as been asked for above.

Why in this day and age do we have to rely on outdated technology? I want to get in a car and go, not have to take a degree in engineering to start it.

[teacake44]

You don't really need a degree to know or find out if the battery is working as it should, just a meter.

lankeela - I assume the outdated technology you are talking about is the battery; you know, the thing they want us to use for powering our cars not just starting them.

When you get the vehicle started, take it for a short run.
Then disconnect the battery leads,say overnight,next day connect leads and if the engine turns over fast the fault will be on the electrical system.If you have a battery hydrometer and its got screw caps on the battery, check the electrolyte readings,the green float in the glass should rise to the top,if it shows red or yellow its the battery,
