 Snippy

Max recommended battery capacity 200 Amphrs!!!

 not max to be fitted!!!

ALL battery chargers are rated in AMPS  OUTPUT

If that is a 200 AMP charger, it would be far far bigger than installed in virtually ALL vans & motor homes!!

No matter what size it is, it should still charge your batteries

.But IF your current draw  "AMPS'on the batteries is higher than the charging current" AMPS" you will just be pulling the batteries down

IF you read the manual you will also see it has :

[a] adjustable voltage settings to suit battery type

self current limiting to protect itself from excess current

In other words unless you are running your batteries down to a very low state of charge with limited recharging time,IF set correctly it will not harm your batterries BUT may not get them to fully charged in the time available  before the next discharge takes place.

IF that is occurring it is quite possible the batteries are  ruined !!

Suggest you do a little reading on batteries & chargers so you understand the correct terminolgy.If you do that it WILL help your

self & other to understand what your problem may be

You say you are running your fridge from the van batteries but you have not told us the type of fridge 

IF it is a 3 way fridge  it could be drawing ALL the available output from the charger with nothing or very little left for battery charging

When not driving ,3ways should be run on 240v or GAS NOT 12V[ unless you have LOTS & LOTS of solar & amphr battery capacity !!!]

Perhaps an instruction book for your model might help??

Apart from that have a good read of T1 post biggrin

Only fridge I mentioned was 12v

I have read the bloody manual and it clearly states that the charge in question does NOT support charging batteries large than 200 ah which I stated above.  I DID NOT SAY ANYTHING ABOUT 200AMP OUTPUT CHARGERS.

YOU SUGGEST I DO A LITTLE BIT OF READING?

I WOULD SUGGEST THAT IF YOU CAN'T READ PREVIOUS POSTS BEFORE PUTTING UP A STUPID DIATRIBE THAT YOU JUST DID THEN DON'T REPLY TO THE POST.

AND YES, TYPING IN BOLD CAPS IS = TO SHOUTING AT THE RECIPIENT, WHICH IS EXACTLY WHAT I AM DOING HERE.

 What page of the manual are those statements on, Snippy.   I have not been able to find them.

Snippy,

1) AGM is a Sealed Lead Acid battery.

2) The 200 Ah battery bank mentioned in the manual is a recommendation only, not a prescribed maximum for the charger. That is noted in both the specifications, and on page 6 under "Suggested Battery Capacity"

3) Page 6 of the manual, under "Suggested Battery Capacity" heading notes that : "It will not have any problem if the capacity of batteries larger than the suggested value. It just takes more time to make the batteries fully charged!"

Your charger may indeed have been faulty, and not able to charge your battery bank, but the information put forward by others is correct, and did not need or deserve the response you gave it. People are just trying to help.

Hi all,
Thanks for your input on this.  Just a quick reminder to please keep posts friendly and respectful. While we welcome differing points of view, we do not allow personal attacks.  
It may also be worth mentioning that although we do have many knowledgeable members who can offer great advice on general technical issues, if you have specific electrical problems it would be safest to consult a qualified expert who can examine your particular case in person.
