Battery gauge low

My depender was off the road recently and when i'd got it sorted the battery was flat, so I charged it for 12 hrs and it worked fine.

However something odd has happened. The battery gauge used to sit on the half way mark when running (just below when running lights/heater) but since I've but the bat back in, it now only reaches just above the red mark.

I've driven it some distances since to charge it up that way.

The landy itself drives and runs fine, but i'm worried about driving any distance with lights on!!!

Do you think this might just be a loose connection on the battery? maybe I should grease it up a bit?

ooo its back then?

it means yo battery is buggered. Wizz it down to Halfrauds tomoz PM and I will check it for yu.

Oh yeah, meant to say Daft.. its back!

Bollocks, I was hoping no one would say that!! Took me long enough to get that one! I was hoping for more along the lines of "you need to tighten the bolts ya dickhead

do yu know what type it is? duz it have 062 or 075 or summat similar on it?

It has this:

59017
12V 90Ah 680A

Its a Banner - Starting Bull battery. Only just over a year old!
