Perentie batteries

generically...

24.4v is what you should see for fully charged batteries with no load on them.

22v is about as low as you want to go for normal discharge 19v for fully discharged with about 18v as your emergency discharge level

28.8 is your nominal maximum charging voltage.

ideally there should never be more than about .3v difference between any 2 adjacent batteries.

fluid level checks in the batteries should be monthly, every 100 engine hours, or 100 hours of use depending on how you are using the batteries.

battery voltage checks should be done with the red switch isolated and with the paralleling cable disconnected (if you do it from the drivers side you can ball park the health of both banks as 24v by simply moving the earth connection from the battery -ve to the -ve cable)

emergency jumper cable or 24v clip on charging can be done from either side of the vehicle directly to the terminals (just don't grab the bridging strap that gets "interesting")

if you put them on the passangers side and leave off the paralleling cable you are in business as is if the alternator is charging. some routine maintenance and charging works will probably see the other batteries come up ok as well and they should be ready to repair and simply bolt in on the drivers side.

your next step is setting up a 12v-24v battery charger if you want to use your existing panel and regulator.

many thanks for the detailed info.

I'll see if i can track down a 12-24 charger easily and it might get me out of trouble for a trip in January where we'll be camped in one spot for a week.

this bloke with the 6x6 sounds like a good guy

..i could be interested in doing the 12v switch-over. The 24v alternator seems like a cool piece of kit - but for the weight of it all, probably far exceeding my needs. I set up a traxide USI-160 in another vehicle which really worked faultlessly.

That same bloke just happens to have a pair of the 12-24v battery chargers lands in melbourne on the afternoon of the 4th after a perth holiday and could easily.be conned into lending you one and setting it up for you as well as arranging a jump pack to.get you out of trouble while.showing you the emergancy start procedure for the perentie.

Not.going to lie. In over 90% of automotive multi battery related situations if the answers not a traxide youre either asking the wrong question or wasting both time and money
