Does anyone know where I can get a replacement battery for an HP Pavillion Pavillion laptop please?

I tried a  supplier in the UK but they will not post it because it is Lithium Iron and the airlines get a bit nervous carrying that type.  Also any recommendations for anyone who can fix a broken power Jack on the same HP laptop?  It works if I jiggle the connector, but is not secure, and with a dodgy battery the the laptop cuts out without warning. 

Thank you in advance.

Can someone tell me where to get a watch battery replaced. Not at jewellers bur cheaper options.

Any  ideas where I could locate a battery for a camera on the Island -  Is there a 'camera shop' anywhere?

Our car battery seems to have given up the ghost. It had been weak for some time, but as of this morning it was a complete non-starter, literally. Fortunately we were just considering a Sunday spin, but the worry of this happening at the side of the road versus at home with no an appointment pending makes me think I'd like to just get it replaced.

Anyone know anywhere in the Caleta/Mattoral/Antigua area likely to have one in stock over the next few days that we can purchase and install oursel
