It's just so heavenly when things run smoothly, but when you start off on your day, and on the first job and things ain't right, it just sets the tone for a sh*t day doesn't it?? My previous battery was failing me from mid last week onwards. It was an old one anyway, so bought a new one on Friday. I didn't have enough time to charge the thing, so just bought if off the shelf, fitted it, and went and done just 3 5bed houses. By the end of the 3rd and final house it was just dribbling water, but okay to just finish off 2 windows thankfully. Anyway, I charged it up as soon as I got home, and was fully charged up, even thou I wasn't to use it again till the Tues as was bank hol. Anyway, Monday eve I charhed it again for a few hours before going to bed, then took off charge while sleeping. Tues I only had a few jobs will 11am, but batt was TDS meter was reading 11.3 by then, and water dribbling. Last night, I stuck on charge all night with my usual c-tek charger, but I noticed the battery was only almost fully charged,and not fully after an 8 hour charge...BUT...got to my first job after a 10mile drive, set up, and on first window was just trickling!!! TDS: 11.2 HELP!!! What's happening???
