Should there be a problem with such battery?

Is the capacity too much?

Would be the alternator able to fully charge it when I take short trips around the town?

What battery is currently fitted to the car?

Could be handy to know and give better advice.

As varooom has put plus don't get too tied into big numbers, do you have a photo of current and/or proposed batteries or make and model number of proposed battery?

Current battery is 65Ah 570A (242x175x190). It's smaller than battery tray box which can hold up to 278x175x190. Battery was almost dead when I bought the car but it's my first car so I didn't notice back then. I didn't even notice that the battery is smaller than the tray box.

So I guess they guy just dropped some cheap old battery there so he could sell the car. But by the size of the tray box I think maybe I should buy bigger battery but don't know which one.
All batteries with form factor 278x175x190 fill fit but they are with different specs like 70-72-74-77Ah and I know that not always bigger is better.
Later I learned that with the car I should receive manual but he gave me nothing. I tried to contact him but with no success so far.

Standard Lead Acid / EFB / AGM?

Standard Lead Acid.

I think there will be no advantage from having larger battery.

https://www.autodoc.co.uk/car-parts/oem/000915105dg

This is the OEM number for the battery that most likely was fitted from new 000 915 105 DG

I suspect someone dropped in a battery just to flog it, but would need a VIN lookup check to assume I was correct.

 

https://www.tayna.co.uk/car-batteries/types/096/

You want to choose "Wet" as you say you don't have EFB/AGM (stop/start batteries)

 

I would stick to around 70-72Ah area if you do upgrade, as no sense fitting a 77Ah monster that might not be any use overall.

Just looking up Tayna batteries and I see varooom already has, I wish I could read faster.

 

I note the list shows E44 VARTA SILVER DYNAMIC CAR BATTERY 77AH (577400078) (096) which is 278x175x190, 77Ah, 780 CCA EN [A].

 

When required and before you get warning lights and messages or battery difficulties you could if required use an appropriate battery charger and maintainer to charge the battery which depending on your car and electrical use you might need or want to use at some stage(s) regardless of how big the battery is.

For the car's 'Owner's Manual' (if that's what you meant) you can download a free Skoda pdf from this link. - https://manual.skoda-auto.com/004/en-com/Models

 

If you read the 'Owner's Manual' and refer to it even for what might seem very simple and obvious things then despite this being your first car you will know more about it than many long term owners and some at Dealerships and garages.

 

First car or had many cars it usually pays not to assume and to ask questions to confirm what you might think you already know (or have forgot more than once if you're old).

 

Good luck.

Neighbour told me about charging the battery after seeing me struggle to start the car every morning. I bought this one:

https://www.hbm-machines.com/nl/p/hbm-druppellader-6-12-volt-3a-van-26-tot-90ah

I left the charger for 48 hours but it never finished the cycle (froze at 75%) and the negative clamp melted a bit.
Nothing changed, still can't start the car as normal and there is backfiring from exhaust when finally does for maybe 3-5 seconds.

Thank you so much for this link, I downloaded the manual and will read it tomorrow.

Do I take it you do not live in the UK as the link is not in English.  Looks very much like you might need a new battery.

That is not good about the current battery or charger but the clamps in the photos look reasonable quality so as long as the negative clamp and wire connection is still sound you can carry on with it and it will be a good reminder to you about batteries and chargers.

 

From the little I can make out the charger is 3 amps which means it will take more time to fully recharge a battery but to me that is a good thing.  The link show 26Ah to 90Ah so it should have done your current 65Ah if the battery was fully functioning.  Note the "Ambient temperature: 0-40 Celsius" if you are somewhere at -20C.

 

This charger will be fine should you need or want to use it on your new battery, I think you may find lots on the car seems better when the new battery is fitted.

Wait and see how things are when you fit the new battery, as you have already found the car battery and its condition and health is  very important to the car, always has been but even more so now there are so much electrics and computer stuff on cars.

 

I take it by your battery choice your car is not a start/stop.

 This is a 1.9 SDI Mk1 - so that will be a no.

Yes, it will put back in what was taken out when starting in a matter of seconds regardless of battery size.

It depends, if you live in a cold climate having a larger battery is a wise precaution, otherwise it's not necessary.

As for charging, it depends, if you're running all the cars electrics flat out on a pitch black freezing morning then it might take up to half an hour to completely replace the cold starting current you used. On a bright summer morning it would be more like thirty seconds.

There'll be absolutely no problem running a bigger battery in your car.

From what I found with mine is that it needs every amp it can get on cold starts. 

I think smaller battery capacity is less work perhaps for the alternator if it is old and tired but if the car and engine are not generally easier starters then bigger and more reserve might be useful especially if in cooler environments and/or greater electric consumption by the driver and perhaps passengers.

 

Depending on cold starting I might go for a smaller battery and perhaps when required (well before it gets too low) top the battery up with the battery charger and maintainer and this battery could possibly (well) outlast the car.
