leisure battery

got my van last year and i have mostly run off the 240v however going on a trip next week and tested the leisure by having the tv combi with a dvd on for some time to see what i would get out of it. After about 30mins the power went completely, surely this should last longer? Any advise pse?

Half an hour is a pretty short time. 1) Perhaps the battery has outlived it's use. 2) Not fully charged. I am sure some folks on here will have a more precise reason of your problem.
If you have only one battery, have atleast 110 Ah, better still a couple, with Solar panels for recharging, if you are not one to go into sites when on the road.
 
Hi depends how you where using the telly if you have a 12v type they will shut off before the battery is discharged (usualy just under 12v's if you had it on an inverter and it was a big un then that alone will drain power to run itself let alone the telly .if its only a small battery and not in good nick then half hour is about its limit at high drain anyway ,all things are relevent in this case and if you dont use the capasity regularly you wont know how much you have till its gon (as they say ) battry's dont like being stored discharged for long times and overwinter in a fragile state will kill an old battery
give us more details and we can tell you whats wrong MOS
 
Leisure batteries have a fairly short lifespan. Check its age if you can, it's almost certainly in need to replacement. Get a 110 and see the difference it will make.
 
power

Thanks for the reply's. This is what I have got:

The tv is 12v, running direct into the 12v socket

Can anyone explain what these display mean (Not got a book)?

I think one is for my leasure bty showing voltage , one is for the vehicle bty and the last is showing the amount of power Im getting from my solar panel?

Lastly I have got plugin on the dash that has max 180w what can this be used for? Is this from Veh bty or leasure bty?

The bty does look a few years old

Think a new bty is the answer

After looking at all your pictures, I would say your battery has had it. I see you have a solar panel. That alone would recharge your battery. Make sure it is wired up properly and working. Lastly the cigarette looking socket with Max 180w on the cover, is for all you other items for plugging in. Your 12v TV can also work from there. I use mine to run my Sat Nav.
 
Need to take a bit of care interpreting those voltage readings and there is nothing I can see that indicates a crook battery

Picture 1 shows leisure battery at 14.3V which might be expected if the sun was shining or the mains was plugged in and the battery was part way through the charge cycle
Picture 2 shows the engine battery at 12.8V - resting voltage or a while since the engine was running probably and indicating a reasonably charged battery. More info needed to comment accurately.

Picture 3 shows Amps ?????? so perhaps charging amps if you have the charger running. Need info on conditions when that image was taken.


Unless I'm missing something critical, no conclusion can be drawn from those pictures.

Cigar lighter socket could well be getting power from the engine battery.

Switch your battery monitor to show only the leisure battery, charge it up fully with a decent mains charger, switch the charger and the solar regulator off and let the battery sit for at least six hours and read the battery voltage. Should be 12.7V or higher.

Switch on a couple of interior lights having a known wattage rating - not fluoros or LEDs - and take a voltage reading every half an hour until the voltage drops to 11.5 volts.

Report back.

Or charge the battery fully and take the vehicle to a specialist battery shop or decent workshop and get them to do a load test for you. Not 100% reliable but will give an idea if one or two cells have had it.


BTW, the panel will put out a maximum of around 3 or 4 Amps on a good day, so I don't know what the 49 Amp reading is unless the engine is running or mains power is hooked up.
