Battery Not Charging

Recommended Posts

We bought our caravan in March and bought a new heavy duty leisure battery suitable for motor movers as we are rarely on a hook up for weekends away. The battery has been great until our last two trips out. Have hooked up to the mains at home to charge as normal only to find when we get to the site after a few lights on the battery just dies. We have a generator so have used this to keep us going and only a small amount of usage of this has actually charged they battery to some degree.

Does anyone out there have any ideas what could be wrong ?

It sounds like there is something wrong with your charging regime and i would check this first.

 

Have you made any electrical changes to the van since the battery has started playing up (added any new equipment - modified wiring ??)

 

I would need to know more about your charger and how you are using the generator (are you using the 12V output from it ??)

The battery needs returning to the supplier for testing along with the paperwork (receipt) and replacement sought if you consider it has failed. .

 

The voltage from the caravan charger needs to be checked at the battery terminals when on the hookup. This needs to be at least 13. 8 volts.

 

If voltage is only 12 or less the fuse needs checking in the charger circuit.

Use of a generator with the caravans charger in use is not a good idea as they can damage the caravan charger if a surge occurs.

 

A generator is OK for a battery charge if it is used to supply 12volt+ to the battery direct only.

Measure battery voltage with the mains unplugged.

Then measure with the mains plugged in.

A normal battery shows about 12. 8volts unplugged and 13. 8volts when plugged into the mains.

If the battery isn't showing these voltages then the charger needs looking at.

Presume battery charger is switched on, if it is this type.

Are the connections to the battery tight?

Is there a fuse for the battery charger?

make sure you get a battery test meter dont take the read out on caravan pannel as true more so if its led read out what van and age is it.
