[size=6]Just replaced 10 year old batteries on Sulito, Parker 325

New batteries read 12.70 o Voltameter, all fully charged

But on the panel it now reads 5.7 V
Has anyone experienced this

Now dont know the real volts unless I expose the batteries and used a voltameter

Anyone else have this?

Regards

Barry

Very strange Barry. I noticed the voltmeter in the switch panel deviates some tenth of a volt from my USB ports that have a built-in voltmeter, but the voltage on Solito deviates so much more. I can’t explain that other than a bad contact.

I had the same Barry. Bought nice big new batteries when I refurbed Blue Moon and the moment we connected them the original voltmeter went bonkers and now reads a range of numbers which only rarely relate to the actual voltage. I didn't mind too much as at the same time I put in one of those NASA battery monitors, but now I do as the monitor itself has just given up after just five years.

I am pointedly not buying another NASA one to replace it but if you did decide to add a monitor instead I noticed that they do a Bluetooth version that would save you having to mount a new device on the panel. Or of course there are loads of simple and small voltmeters.
