I have fitted an Auxilary battery under the bonnet, a 105AH Lead Acid Deep Cycle. Do I hook it up with the standard old isolator or a DC/DC charger. I had dual batteries in my Troop Carrier using an isolator, the deep cycle constantly had corrosion on the positive terminal & the battery clamp was slowly disappearing. The alternator puts out 14.2volts in my 105 series. Thanks.

Hi Enormous ,further to my earlier post re DC DC Chargers ,the attached link may be more self explanatory in what a Dc Dc charger does that an alternator does not ,especially in vehicles made after 2007 ,where the alternator is limited in its voltage ,for environmental reasons ,down to 12.7 volts not the 14.2 Volts ,which is there for a short time .
regards
John

I have a landcruiser 4.2 turbo manual with a triple battery set up. Two batteries under bonnet in factory location.a third battery (wet cell deep cycle 100 amp) in the rear of the vehicle,plus cable to tow bar to charge battery on camper.
I use a simple isolator purchased from ABR an advertiser on this site.
At idle, voltage at front batteries 14.3v ,voltage at rear battery and trailer plug 14.2v so no need for dc charger in my opinion.
I have used this setup in all my vehicles over many years without problems.
All the best.
