Well, Antony hates using AA/AAA rechargeable batteries but he uses NiMH rechargeable batteries. (All Energizer branded if you want to know.)
Related to Sony AC-VQ900AM (dual battery charger and AC adapor) entry, here's another battery topic. This is a brilliant product I saw when I was window shopping, and I can't resist myself not getting it - Energizer Rechargeable Dock & Go Charger. (to Don: Antony is poor.)
About a year back, I decided to try out using rechargeable AA batteries (NiMH). This is the charger I got back then, Energizer Ultra Compact Charger.
There's a problem with NiMH rechargeable batteries. Not all devices can be used with rechargeable batteries, simply that standard AA or AAA batteries provide voltage of 1.5 V (volts), while NiMH provides only 1.2 V. Also, although the name "rechargeable" sounds great, but a NiMH battery can only last only 100s of charges over its lifetime. Most non-brand NiMH batteries lose their charge at about 1.5% per day. In plain words, rechargeable batteries won't perform well after some time and some uses.
Why did I buy Energizer Rechargeable Dock & Go Charger since I already have an Energizer Ultra Compact Charger? Charging time is obviously the number one decision reason. Spending 8.5 hours on charging batteries while on holiday is obviously a super stupid idea. Timing 8.5 hours is obviously a big hassle.
Other benefits of Energizer Rechargeable Dock & Go Charger include the charger pods that can be used for storage and travel (as well as charging). The Energizer Rechargeable Dock & Go Charger is also a smart charger, if the batteries have some power left, it will adjust the charging time. It also powers off automatically, hence you don't need to set a timer just to remove the batteries after charging.
Before you guess, I am not converting from alkaline batteries to NiMD rechargeables. But then why do I buy so many rechargeable batteries? Well, it would be wiser to use NiMD rechargeable batteries in certain situations, for example the GPS tracking device for photos (Sony GPS-CS1KASP) requires an AA battery. And the manual states:
Also the flash for camera requires 4 AA batteries and works with NiMH battery.

And the important news on the rechargeable battery breakthrough:
