Voltage drop

Alloy c/t,
I asked a question and thought I was being polite, but by the way you seem to be asking how the ---- do you know that you are losing 6ah a day seems a little inappropriate( don't you think??). I don't appreciate being talked to in this way and if you can't speak to others nicely then don't speak at all!

Hear, hear! ( Applause from the Pezza Peanut Gallery )

Hi Greg,

Can I assume that you have measured a leakage current of a 1/4 amp thus giving you the 6 AH per day?

Cheers

Jerry

Hi Jerry,

The electronic meter we had installed tell us what we are using and what charge if any is coming in, and it says that there is a discharge of around 0.2-0.3 amps at any given time of the day(all day). And after checking it after a day, overall has dropped around 6amps. This happens every day, untill I put it back on charge that is.

Cheers Greg

Steve,
What do you mean by saying 'there are a few out there still..!! want the reader's to help them ...and they are a bit past that stage !!'
please explain???

Thanks Bob,
The batteries are wired up to a 30amp charger that is mounted in the front box, this is hooked up to a 240v plug that I charge via a 15amp ext lead at home. The batteries are 120amp Fullriver AGM. It is when I turn off the charger, the batteries drop around 6ah a day. I don't mind leaving the charger on all the time but I thought that 6ah a day might be a bit much. Anyway thanks for your help.

Greg

It sure is unlikely to be a dead short!

Evening Sandman,

All the electrics are turned off. I have a fused switch panel mounted in the front box, so we can turn off lights etc from outside.(so we don't have to open up the camper just to turn off a light if we forget)
We have an electronic meter to tell us what amps we are using or what is coming in via the charger etc.
The camper was rewired by a company on the sunshine coast(they are not an advertiser on this site), 8b&s wire throughout. 50 amp anderson plug to charge from a vehicle( not currently used, but will be soon), 50 amp anderson plug for a fridge(mounted in the front box, not used at the moment as we don't have a fridge)

Might have to look at a current meter of sorts to find this as it has gone on since they rewired it.

Thanks for your assistance and advice, greatly appreciated

Cheers Greg

Does "all the electrics are turned off" include your electronic meter? If not, there may be your answer, meters do consume power too.
If there is any indicator light on your electronics panel, it does not run on thin air either.
Also, batteries are not perfect either, they do suffer from self discharge to some extend. How much of it depends on various causes, such as age of battery, type of battery, temperature, etc.
Good luck with that one,
Klaus

Morning V8 Troopie,
The electronic meter has no lights on it, and realise that it must consume some power, but didn't think it would consume 6ah a day. Might have to make some calls to find out.
Thanks Klaus for your advice, greatly appreciated.

Hi,

If you meter _Affordable_Storage_Drawers.aspx as little as 250mA then there is your 6Ah in 24 hours!
From you description it sounds like it is a fairly smart device with possibly a microprocessor. That could easily draw 200mA or so.

Cheers

Right on Derek,

I chose to ignore them.

Most Solar Panels have a diode built in to prevent discharging batteries.

Mike

Thanks cipher, might go and get the batteries tested just to make sure.

Cheers Greg

Hi Trevor,
Good idea

Greg
