Waterlily: Anal about batteries

Saturday 24 January 2009

Sorry for this, but I want to refer back to it to help my understanding of the battery systems on Waterlily.

Brian and Diana on NB Harnser said...: Interesting, but how did you manage to get two sets of batteries to the same percentage charge at exactly the same time.; 25 January 2009 at 18:29
Nev Wells said...: My error, the smartgauge shows the % charge for the leisure batteries only.

Halfie said...: Nev, how is it that at 80% charge it reads 12.8V and yet at 63% charge it reads 0.1V more?; 27 January 2009 at 21:43
Nev Wells said...: Halfie,

The blurb says it takes a few charge and discharge cycles before the wizardry knows the true state - so it is still most probably learning. Hopefully a few more cycles will see it settle??

I try to do this with a simple voltmeter, which can be a bit tedious but I usually try and take the measurement with a similar load and after a few hours have past since I recharged the batteries.
This is why I am interested in how you get on with this instrument, it should make it so much simpler.

Although if I measure anything greater than 12.6 I think that my batteries are fully charged. I will start measuring just after a recharge, instead of after a days discharge.
