Guess I should have been more specific in my question, I realise what the purpose of the card is, just wondered if someone could tell me the make/model.
This is for an A500 though, not an A600.
Unlikely to be for an A500+ too as all 1 MB expansions I've seen carried 8 chips.
EDIT: It's a Datalux model, the SV-7xx names are characteristic of their Amiga product line. I have an SV-702 here and it's an external floppy drive.
EDIT2: Here it is
EDIT3: Well, it's not identical, your card is apparently a later revision using SMT RAM chips and not DIP ones as the one pictured. The Datalux logo is missing as well, might be an unbranded clone, but the SV-701 code is unmistakable. They were based in Germany.

Thanks a lot, now just to see if I can clean it up properly or not

Interesting indeed. I feel I've seen this kind of chips on Amiga stuff before but I'm close to brain-mush now and can't put any usable thought together

Thanks BLTCON0!
I also have this strange little card in my spare part bin and I never found out who definitely built it.
You are right, SV-701 points to DataLux. According to google they obviously sold different versions of a 512k RAM extension under the SV-701 brand, so why not this one.
The "funny" thing is: The leaking battery did almost the same pattern of damage to the pcb of my card
oh:

NP mate. Take a photo of the damage, it should be interesting!
Thanks! Yours was a bit more well-behaved 
I suppose the similarity is due to the way the battery leaks - same batteries, same leaking behaviour?

could be, maybe also the kind of coating of the pcb.
I have another kind of RAM extension with battery damage where the coating is still OK but all components near the battery got serious acid damage. The acid seemed to creep under the coating and oxidized all metal parts it could reach. The battery type was exactly the same.

For both cases spirit vinegar or lemon juice poured over the area will clean the oxide, just use a toothbrush (an used one or from an Atari user) to finish the clean.
Then wash the board with tap water and let it dry for two or more days. After all dry you can apply nail varnish before put the boards in use again.

Hi rkauer,
thanks for the hints!
Lemon juice or spirit vinegar on a pcb, why not! No problem, both I have hanging around in my kitchen, so I'll give it a try.
But I have no clue how to find an Atari user with a toohbrush. I always thought those guys never use such things like toothbrushes or showers

Lemon juiced mine, have a dead resistor on it so going to replace that and have a play to see if I can get it working again.
