Only thing is it’s an AGM to which I believe I cant because of the high output rate of the D3s alternator
How ever am looking through the range of the odyssey batteries to see what wet plates they have
Always grateful

The optima yellow top second battery (also AGM/not wet plate’s) in my D3 with split charge is from 2013, fitted for a australia trip and then shipped back to Germany (the D3 incl the battery that is) is still 100% healthy.. that is 7 years now.....
Has no issue with mentioned “high alternator output” or otherwise...
Other series in the odyssee range are not by default the deep cycle resistant battery’sBest regards

Many thks
Indeed think that would be the way to go with the aux battery , would at least be nice to have a back up for the main battery via the split charge system
Think my aux battery is an enduroline
At least this time I’m not having to buy a battery straight away and can spend time researching it properly and get the correct set up
Plus can start looking again to fit a solar on the roof
Thks again and always appreciate the help

For your type of motoring fit an AGM and your troubles will be over, although the D3 does charge at a higher rate than recommended for an AGM it only does this for the first few minutes on a cold start and therefore does not have time to overheat the glass mat that divides the cells.
An AGM charges much faster than a wet cell and at lower volts And holds the charge longer which makes them ideal for short journey motoring. Also leaving your present battery until 12.4v before charging is to low for a long life, get a tow plug adapter and top charge more often.It can when others can't,
It will when others won't,
It goes where others don't.

Many thks
Will do, have got a lead to charge via the 12s socket
Daft question is there an output limit for the AGMS please , mine will normally run around 14 - 14.5 Vdc
With the T max split charge system would it be better to also fit an AGM aux battery plse , currently is a leisure battery
Just trying to establish things so I get it spot on this time with battery set up
Extremely grateful as always and appreciate the advice , thk u

Forget these voltages please...
These discussions are for school teachers and maybe IT guys....
Look at the practical side..
Your main is in the risk of deep charging you “told” us in a way, so you need one who can handle that better than a ordinary (or cheaper) one...(“standard” Bosch, yuasa, varta, and most of the other brands)
Follow M3PO about AGM. And buy the best deep cycle AGM you can afford (my advise) and charge it as often as you can..
Do you really use the second battery a lot as a auxiliary battery? Or not really?
If yes, it is best to have it also very deep cycle resistant... if not, leave it alone until attention needed, the split charge system copes very well with totally different battery’s.Best regards

Hi motolab
Perfect and that clears a lot of it up, do apologise asking the daft questions
So will indeed sort out the main battery now I know what I’m looking for
I originally installed the T max split charge system for camping and a back up for the main battery , however when the main battery has gone flat I linked it via the T max controller and done nothing , did think it would give just enough to the main battery to allow the disco to start , but alas wasn’t the case
The T max will allow solar, via a MPPT controller to wire in a solar panel into the leisure battery which I believe when the landy is off will put charge across from the solar panel through to the main battery
So at the end of the day would like the solar to keep most importantly the main battery topped up, when the weather is bad can easily plug my ctek in via the 12 s socket
To which the MPPT should see the voltage and turn off the solar
Also having the solar would be a protection if I’m away and not use the landy for a month , that way without having the CTEK plugged in the solar will take over
Hopefully doing this set up I’ll have different options or keeping the main battery topped up whilst away and at home
Hope I’ve got this right and hopefully ur not banging ur head against the wall
Thks a million and indeed once again apologise for the daft questions

A leisure battery is not designed for cranking, they just don’t have sufficient CCA to turn the tdv6 over. Relying on solar during bad weather is a no-no, they need sunshine and plenty of it. If you think you have a rogue battery drain when the vehicle is asleep check all none original components first including the T-Max solenoid and system they have been known to drain batteries when the car is asleep. If you are determined to use solar simply buy a unit that can be plugged into the tow-bar socket or the power socket (cigar lighter, needs making permanent live).
On my old D3 dual charge system I used a calcium battery for a Peugeot 307 diesel, this was a manual system with the solenoid operated by a switch in the cabin, when switched off it was totally isolated, it got me out of trouble numerous times after the main battery failed to start the engine.It can when others can't,
It will when others won't,
It goes where others don't.

Hiya
Bless u as always for the advice
Indeed found out the hard way ref the battery and my mistake as I assumed the leisure battery would have provided enough power to the crank battery , live and learn
Double checked everything and no drain anywhere
Am going to spend the next few weeks checking the main battery voltage to see each day what it drops by
After 4 x days it’s currently on 12.56 Vdc
But at the end of the day will at least buy a decent AGM battery to replace the exide
As thinking today if I do that I can at least mess around later with solar if so req and understand where ur coming from ref weather etc
Know I over think things , so will start with a new main agm battery
Just so very grateful for the sound advice, thank u

Found this and looks like it might be a good replacement for the current main battery

That is Not a Odyssee..... or even an Alternative Deep cycle battery
Do / Choose what you want...can be a Good battery but i do Not understand why People are not going For the high lead quality Deep cycle in These cases..
Start/stop cars do also Regeneration of Breaking Power into current, so also on Short Runs.more reloading. ..the D3 does not.... That is your problem isn‘t it?Best regards

Hi
Looked at the Odyssey PC1350 but was nearly £300 which is a bit dear for me at the moment
Good job I put the link up and thks for the heads up as I assume that not the correct type of AGM
Appreciate u letting me know and will have another search
