How To Charge A Battery?

Recommended Posts

Most modern caravans have an on-board power supply - if you connect the caravan to your domestic mains power at home, the power supply will charge the battery to about 80% (as it's 13. 8v instead of the 14. 4v needed for a full charge) which most caravanners regard as acceptable.

 

If you want to fully charge your battery and/or extend it's life, you'll need a smart car charger like the Aldi/Lidl special promotion at £13 or the cTEK XS3600 at £50

Sorry to muddy the water a little and this only applies to the last couple of years, but, many of the latest 12v power supplies in caravans are infact true battery chargers, the ones going wrong in Swifts at the moment being a case in point.

 

These are pucker switch mode smart chargers with controlled voltage of 14. 4v for full charge, but, with the possible added advantage of high amperage outputs in the region of 15 to 20amps or more, this giving faster charging than most standalone chargers.

 

Without documents it's difficult to know whats fitted but a cheap multimeter will show what voltage is being delivered to the battery, if it's a newish van and rising well above 13. 8v then it's most probably one of these full blown chargers.

 

If so, then using a standalone or even leaving the van hooked up is not particularly required, simply hooking up 24 hours before use should suffice

Gary,

 

Do you know what type was fitted to a Bailey Senator in 2007?

 

Thanks

No sorry I don't know, the ability has been around for a few years but most had/have the option of being switched to permanent 'maintenance' charge, ie 13. 8v and this was always selected.

 

I note with the 'Nord Electronica' as fitted to Swift among some others I believe, there is not an option to turn it off?

Anyway found this article, I note the prices is wrong so out of date at least on that score but explains a bit more.

To date I've found out, only Swift are using this type charger made by Nord, in general, these are a powerful 18A three stage fan-less charger.

If you should want or need to replace an existing charger, then Nord do a range of suitable units at fairly reasonable prices considering their duel use, see here
