My Penta has a Hercules 10 power supply and charger fitted. This question often crops up:
When parked at home should the 220v supply be switched off or not, if left on would the battery be overcharged.?
If the battery is disconnected could one still operate the fridge off the main supply?
Thanks,
Graham

If the Hercules is a smart cherger then it should not over charge the battrey.
If not, you should fully charge the battery, after which you could disconnect the charger from the battery or the charger from the 220v supply.
The fridge should not object to running off the 220v supply alone, if you choose to leave it on, when at home.

Ouch, I have seen "smart" chargers malfunction and definitely overcharging batteries. Had a client of the weekend with a very "smart" charger supplying a rekatively high voltage for too long that you can actually hear the battery boiling inside.. dont believe hercules is a "smart" charger, its basically the cheapest power system jurgens could find

If the Hercules works fine then you can leave it on.  It will not over charge the battery unless something goes wrong.

Just check the battery at regular intervals like once a week. You will clearly smell the acid when it is over charging.

The only thing that can damage the Hercules is a power surge like maybe a spike in the electricity or lightning close by.

As an example I had two Pentas over a period of 14 years and never had charging problems.  As a own rule I alway leave the power on to keep the absorbsion fridge running. Had the Classique for about two years when I got into it one time and smelled the acid. This was just after a thunder storm.

So best would probably be to attach one of those red Ellies power surge plugs to the input side of the Hercules as another precaution.

I would never leave the charger on permanently in any caravan, with any charger.. in the last 1 years I have seen and dealt with many many caravans and trailers whose chargers either fail and batteries drain completely, or opposite and charger malfunctions and overcgarge.. why take a chance?

Hi

I am confused now. If you leave the charger off the battery would be of no use after a month or two.

I have a permanent display Voltmeter attached to the battery in my caravan to check the condition thereof. I also disconnect the battery when not in use to prevent any charge drainage, by way of a cut-out switch. Have had the charger on for long periods but with no problems, although in the 7 year life span of the 'Van, I have replaced the battery once. My caravan came equipped with the Hercules 20, so am not too au fait with the difference between this and the "10"

I also don't think a Hercules is a smart charger. I put a switch in mine to cut the power on the charge supply side. I still needed the 220V plugs en breakers to work.

I added a smart charger to keep my batteries charged (x3). Can still use the Hercules side if I need a faster charge. You can hear the smart charger switching on and off and keep the charge as 13.5V as per digital reading and color lights.

Using this system now for 3 years

Please tell me where the switch is to disconnect the charger only on the Hercules 10.

@ Ben

I took mine's cover of and installed a switch (toggle) on the line going to the positive off the battery. I drilled a hole on the side of Hercules. I can still use it to charge battery, but the my smart charger must be of. I do have a change over switch (with a off position) from Solar or smart charger. That need to be in off position if I want to use Hercules 12V charger.

But you must "hou kop" not to mess up. I drive with change over on "off", when altenator is charging batteries

I still needed the 220V breakers
