Woohooo! My battery order from Servaas arrived today via Express Post 
I ordered 4 X 4 2700mAh AA batteries along with the 8 cell charger as seen below. If you’re on Whirlpool, look up Jeff and he will set you up with a discount.
From all accounts, these batteries are used by many photographers and most seem to swear by it. I just tested them in my 580EX II and 430EX out of the box and they charged up both flashes almost instantly! On the 430EX I also heard the distinct ‘zing’ while charging up – something I haven’t heard for awhile with my now old Energizer rechargeables. When I’m done charging these new Powerex ones I’ll condition the Energizers and hopefully they’ll come back to life. More batteries is definitely better than less 
I thought why not take a picture of the batteries that feed my camera too
These should last for tomorrow’s wedding and an engagement party later in the night. Catch you guys later!

Retail you can get them at J-One at Amcorp mall but I would suggest buying PowerEx from Shashinki.com. Its cheaper there.

Luckily Mark has saved the day as I’m not sure where you can find them in Malaysia. Thanks mate!
For some reason your message went to spam though

Hi there, I’m not so sure but I would think your best bet is shashinki.com. Yes, the Imedions are indeed Powerex but I would recommend the Powerex 2700mAh ones.
Might be worth a look or ask around the clubsnap forums too?

Hey Justin,
Since you’ve used these for a while now…… how do you find them now? Still as good as what you’ve said in your post?
Interested in getting some….. keeping 5 flashes with fresh batteries is costing heaps!!…. LOL

Hey Kev!
Indeed they are, it holds charge very very well too. Even after several weeks after a full charge they remain almost full – I always check before a shoot to be safe. A couple of minutes later and they are ready
Definitely highly recommended! You will find that most photographers swear by these batteries too! In your case I’d highly recommend the 8 cell charger
