Where can I get a new (and hopefully longer lasting) rechargeable battery as pictured? 

 

Look on Lazada for an 18650 battery.

 

(Assuming it's 18 mm OD and 65 mm long)

Amorn has various non standard batteries

Most of the 18650's on Lazada and AliExpress are fakes.  The only good thing is that they're cheap enough to buy several of them for backups. 

 

I've tried and tried to get original Panasonic or Sony or any well known brand name because of all of the reports of electronic ciggies exploding (almost certainly down to dodgy batteries rather than the ciggie itself).  I haven't tried Amorn, but would worry that they bought the copies (in good faith I suppose).

It may be worth trying at Thanaporn Electronic Components on Prapokkloa Rd near Chang Puak Gate (search for QXVP+XR in Google Maps). Be a little careful however - some 18650 lithium batteries have circuitry to restrict their current (for safety reasons).
