Hi All,
After a small battery issue yesterday I've been staring at the VRM for like 4 hours now watching it like a hawk. I've noticed this before this bubbling battery issue, but why does the AC Grid voltage fluctuate between -5, -4, -3, -2, 1, 2, 3, 4, 5 watt? is it just interference or something should I be worried about it.
* If you are wondering battery issue, I purchased 8 brand new Hybrid Gel SLA batteries yesterday and stupid enough I forgot to multi-meter the voltage turns out four of those "brand new" batteries from the shop had 11v rest had 13.1v and they were making funny popping, sizzling noises inside. I did have a massive whinge at the shop owner. saying are you trying to blow me up. He said they won't blow, just wack them on a charger overnight if they don't come back up bring them back and I'll swap them over and test each battery out of the box.
Note they were fresh out of the box, cut the sticky tape and everything.
