Gibbo,
I have a BMV monitor, great, I have had quite a bit of enjoyment out of it but got pissed off with percentage readings so I bought a Smartgauge to supplement it. Not quite as much fun as you can't fiddle about with it as much but that's ok as I only want it for percentage readings.
Now the thing is you may or may not recall my AGM batts are down to somewhere in the region of 45% capacity left, might have improved a bit since I adopted regular 8hr raised absorption charges, but as I don't know what level of inaccuracy my Smartgauge is reading I can't trust the reading.
Is it possible for you to give me a rough ballpark figure? If it is within, say, 5% then I could get by until our batts give up the fight for survival and we get nice new ones.
Also at what level of batt capacity would the inaccuracy be impractical.
Thanks.
