Car battery health using a MFT?

[shocksl]

Can I check the voltage of the battery using my megger mft1722?

If so what are the steps and settings I'll need to put it on ?

Thank you.

Do they make a megger 1722 ??

The megger 1700 series should be able to measure AC/DC voltage from 10V to 600V.

Set the Main rotary range knob to volts
(The position of the right-hand rotary range knob does not matter)

Using two test leads, connect test leads to the L1 (+ve) and L2 (-ve) terminals.

Taking a voltage measurement of a car battery isn't a definitive way of telling if the battery is any good.

Oh thank you so much.

Would I need the car started to do this ?

With the engine off you should get a reading around 12v. With the engine running that should increase to around 13.8v

With the engine running I would expect the voltage to be between 14.2v - 15.7v depending on the alternator and battery technology fitted to the vehicle. EFB and AGM batteries generally charge at a higher voltage and depending on the state of charge of the battery the alternator will adapt the charging voltage to suit the level of charge in the battery

You can test the voltage, but not how “healthy” it is in respect of whether it can turn a starter or not.

No, the engine shouldn't be running and preferably with the battery disconnected from the car.
