Disco 2 Battery replace

So I put a new battery, fuel pressure regulator and new fuel pump on a week ago, won’t start again and it’s telling me to replace battery again when I tested it! Can’t be right can it? Brand new battery and it’s telling me to replace after a week, it’s got to be something else that’s screwing them up right?

What is telling you to replace it?

Cheers

Battery tester, come to start it this morning and wouldn’t start so tested battery and it says replace

Have you tried charging the battery?

Did it ever start after you replaced the FPR and fuel pump?

Cheers

Yea battery is on charge now, it’s been all right till today, replaced those last Sunday been good for a week, started every time and everything till this morning

What size battery you fitted?

Cheers

That one

Does it even turn over?


Cheers

Yea just won’t start, was fine from last Sunday till today

Is the alternator doing it's job? did you at least measure the charging after the new battery was fitted?

No I didn’t check it was meant but never got round to it, checking that now
