Maplin deep cycle solar batteries

[River Song]

OK - I am going put to buy a deep cycle battery thingy.

Now can anyone give me a (blonde) answer

The one Im looking at £89 is a 125 AH battery
I guess this refers to Amp Hour. I know what an hour is
and I can get a definition of an 'amp' but it makes it no clearer.

Is 125AH good? If so why? How long would it last before it needs recharging if it was connected to a 1KW or 2KW inverter.

If I connected two together would that double the time?

Can it keep my Harveys Bristol Cream chilled or my Hair Straighteners hot :-) :-)
