How much Battery Drain

According to Rule the 500 uses about 0.20 amp hours per day in sensing mode and the 1100 uses 0.25.

I think Rule may have got this wrong from what everyone is saying.

Ok all sorted,
I have purchased a nice Honda generator to run 24/7 and an oil tanker to supply the fuel, as a secondary backup system I have run an extension lead out to the boat (boatyard weren't to happy but I talked them round), might have a small short in the system as a lot of fish are floating upside down round the boat, hay ho.

It seams to be working!!!!!

I feel your frustration however this is probably one of those suck it and see situations.. Before you go spending more money on solar panels why not give it a go? according to the Rule figures your battery shoud last well if there is little rain, and if there is loads of rain then clearly you are going to need to keep an eye on the battery level...

Just a quick update, she is fine on the mooring no visible drain starts first turn etc...
Just need to decide to anti-foul or not decisions decisions but I better post it on one the other notice boards.

Many thanks everyone.

I asked my neigbours why they had there garden solar lights on the roof of the car during the day...they told me

" they were not charging when in the ground so thought moving them closer to sun will help"

What did you do in the end?

I had one of those auto Rule pumps for 4 years running direct of an 85AH battery - always managed to start a 200 opti off it even after a lot of heavy rain and the boat was dry. It did however pck up for the new owner a month ago ( not bad for a rule to last 5+ years) .

No solar panel to top up either.

I stuck an old solar panel on the battery, had to strap it to the auxiliary fuel tank in front of the consol, so managed to break the panel straight away on the first big wave, had it for years so no loss but I think it still works.
Next year I will get a flexi panel to sort that out either a 5 or 7w. The main thing is that I don’t have to lug my battery jump-start pack out with me in the tender (famous last words).
