Hi Guys,
just a question for the electricity minded member of this forum...
I have an Exide ED5 and for the past 3 days I have driven around 300km+ with no load on the AUX battery. My alternator (with LeighW's diode in it) is pushing out around 14.1-14.3v on start up and probably settling down to 13.8v after 30 odd mins of driving. The voltage went from around 12.1-12.2 to 12.47. For the past 3 days, it has remained at 12.47 and will not go up any higher. I've tested the battery after about 2-3 hours after I've turned the engine off to get a proper reading on it.
Now I would like to know, is 12.47 = to 100% charge on an Exide ED5 which is about 5 months old, or is that not quite full?
I rang the shop who sold it to me and they reckon that new batteries they have on the shelf are reading 12.49/12.50 and that they believe 12.47 is just about full (95%). Then I rang Exide and the bloke I spoke to was absolutely useless and told me that ta full battery reads 12.something! Absolutely useless information! Then I spoke to one of the boys at Piranha and they reckon it should get up to 12.8 after having been on a 3 stage 20amp charger. But I don't have one of those and want the battery to just be recharged off my alternator.
Now, is 12.47 a fully charged battery or not? Is there another way of getting it to sit on 12.8 with the alternator and LeighW's chip?
For those who have an Exide ED5, what are your readings when the battery is fully charged?
I'm thinking that this battery is a bit of a dud as I'm not getting very much life out of it when I have my ARB 47L fridge running and considering getting a:
- Century Marine Pro 720 100AH
or
- Century AGM C12-100DA
Anyone have the above two and can give me pros and cons? Is the C12-100DA going to have trouble being recharged in the car given that it's AGM and they tend to need a higher charging voltage?
I just want to have a fridge in that car that is powered for at least 48h without driving!!!
Also, running this system through a redarc isolator and fairly thick cable. Getting a .2V drop through the isolator and cabling. (Main reads 14.2 while engine is on, AUX reads 14.05 while engine is on.
Cheers,
Lorenzo
