Even if the alternator output is good, that doesn't mean that your battery is fully charged.
Think about the way you use your car: short journeys, frequent starts, current consuming accessories in use?
Particularly in the winter, most people's batteries are partially discharged and are not allowed enough time to recharge.

So in the first instance I would recommend that you buy a compact and well engineered mains powered charger from the C-tek range. Overnight your battery will be restored to full health.

I have always used the highest amperage batter available. Take the dimensions of the Battery box, including maximun height and establish location of posts and go for it. This approach has served me well over the last 50 years or so...Always like a few amps in reserve.
I am currently using a Varta 72 amp which more than copes with my requirements - well my Rover.
I remember, that upon tests to establish best battery for our usage, we would take the battery which lasted longer at 100 amp discharge. In those days it was Exide..
cheers

Also, I have aftermarket sound system and when this is on, I notice the lights dimming so I'm looking to upgrade the battery. What do you recommend?

Many thanks.

The dimming, is volts drop - volts drop will always occur to some extent where wiring is shared. The least likely cause of such volts drop, is the battery, most likely cause is connections, earth connection and battery connections.

Forgot to mention, I ended up buying the battery in the above link and fitted this today. And wow, car starts so much better now. And I can still fit the battery lid. Thanks for everyone's input.

None of your issues sound battery related.

ICE shouldn't be using the battery at all.

My car had upgraded wiring from the alt and to the earths, and a massive new Bosch battery and the interior lights still dimmed slightly when using the windows. My new car does exactly the same.

EDIT - Nevermind too late.

ICE wasn't an issue in the first place. The old battery was just generally worn and got weaker over the years. Anyway, new battery seems to be good.

Me too but... Varta (US owned Company) make them for Bosch and are identical + cheaper.

Thanks for reporting back.

With diesels, the battery takes quite a hit prior to cranking as the glow plugs take 50A to 60A for around 10 seconds. When cranking follows, the strength with which the cranking takes pace is quite a good indicator of the state of the battery. This can have an effect on lights etc. dimming especially when the battery is being charged up towards maximum capacity following a start.

As I stated earlier, I would always test or replace the battery with a new or known good one before worrying about the wiring etc. as it is the easiest one to address and is unlikely to prove a wasted action.

With modern cars and diesels in particular, we should think of batteries as consumable items with around a 5-year replacement cycle.
