I have a problem with my battery draining when keft over night, also when i am driving the ABS and handbrake light appear around 2000rpm

New battery

Not the alternator

Those lights have been on in my TH for too long now but mine stays on permanently, I have to take it to a dealer to get the problem resolved as the local brake place could tell me via their computer that it's a problem with the ABS but that was as far as the TH computer would let them in.

As for the battery maybe an interior/boot light is draining the battery, I changed all my interior lights to led as they apparently use less power and definitely do give a much better light.

Do you have a multimeter or can borrow one?

Your battery should sit around 12 volts and when car is running around 14 volts from alternator charging.

With the multi meter set to run in sequence take the clamp off the negative terminal and connect a wire to the battery and to the clamp. If it is showing a drain pull fuses till the drain disappears to identify where the drain is coming from. If there is no drain your battery needs replacing.

ABS light: try cleaning the sensors on the wheels. They are magnetic and pick up any bits of metal. Worked on my TS with ABS anyway.

a bad drain is anything over 50mA or 0.05A

I forgot to mention that bit. Thx
