Hi again norto, as posted, there are a number of factors that can effect the charging time and the times I posted are based on worst case scenarios.
Flooded wet cell deep cycle batteries take the longest time to recharge but will probably give you a much longer life span than comparably priced batteries.
Also as posted, while on a trip, you don’t need to fully recharge the battery after each use. Simply replacing the bulk of the charge is usually enough to cover your needs and the replacement recharging time is based on just how low the battery is when you start recharging it. The lower the battery, the longer the recharging time is going to be

The battery had dropped to 11.7 v and hadnt recharged enough
to run the fridge after a half hour of drivingPete
The battery is sounding slowish, can you check the specific gravity? Get a sparky to do it if you have no gauge. That will tell if the water acid mix is ok, Also make sure the earth point is strong as that can impede charge speed. The Optima deep cycle is different but mine seems to be charged after 3 to 4 hours from a 2 day stop, It just makes 3 days when fully charged.
After a half hour charge your battery should have had a surface charge that reads over 12v, it would not sustain that for a long time but it should get to a position over 12v smartly even when it has no depth of charge to back it up. Double check posts are ok and earth is as critical as I mentioned above.
On another front the LR Manuals you gave me have a new home. My Brother in law promptly claimed them. He has 2 Range rovers of the right vintage and a 96 Disco diesel.
All the best

Peter, can you give us a rough run down of your dual battery set up, EG auxiliary battery location, cable run and size etc.
See if we can’t get your battery charging quicker.

I have a 46T century deep cycle battery. It is connected via an
isolator that charges from the alternator when the
motor is running ie when the ignition is on the deep cycle batttery is connected
to the main battery and isolated when the ignition is off.
I was running 3 mm cables for both power and earth.
today i have doubled the size of both.
Any ideas
I have to do 120ks tomorrow, ill check to see how much caharge is
in the aux batt when i get backPete
There is a Piranha battery kit for the spot. It has a metal tray that attaches to the body and then the bolts are attached to the sides of the metal undertray.TDV6

Hi ianv and Peter, you don’t need a battery tray for the D3, it comes with an auxiliary battery compartment already set up to take a battery and all you need is the genuine Land Rover D3/RRS right hand side battery bracket and two bolts.
The right hand side battery bracket LR part n# is YJF 500100
The long bolt LR part n# is XYG 000051
The short bolt LR part n# is XYG 500061
The three items will set you back about $20
Peter, you will also have to change the size of your cable. The cable you have is so small, it will cause such a voltage drop that it will take anything up to 15 hours, or more, of continuos driving to be able to recharge your battery if it’s low and is most likely the very reason why your battery only rose a little and then settled back to 11.7v after 30 minutes of driving.

I've been treating my D3 to some extremes, The tray has helped absorb the pounding of an 80% outback travel life and also craftily left me the option of having an easily restored pristine battery compartment, Captive nuts intact, if I resell later, Although at this stage I am lokking at keeping her another 3 or 4 years. What a great vehicle it has turned out to be!

Hi ianv, again, there is no need for a tray.
Your auxiliary battery is sitting in what would be the cranking battery compartment in a left hand drive D3/RRS and your cranking battery is sitting in what would be the auxiliary battery compartment on a left had drive D3/RRS so as you can see, there is no difference in either compartment and your existing cranking battery does not come with or need a battery tray.
Your cranking battery is held in place with the same type of bracket, only its shaped in the opposite direction.
