If you really want to use alkalines, I'd recommend Gp Ultras, cheap and good
Btw, found this for Nikon SB900.
(Battery type/time to recharge/# of flash)
- Alkaline-manganese (1.5V) : 4.0 sec. / 110
- Lithium (1.5V) : 4.5 sec. / 230
- Oxyride (1.5V) : 3.0 sec. / 125
- Ni-MH AA (2600 mAh) (rechargeable): 2.3 sec. / 190
NiMH delivers the best recharge times but last marginally less compared to the much more expensive Lithium batteries which have the worst recharge times. Alkalines do not last long and have poor recharge times.

Canon EOS 5D, 24-70 f/4 L IS, 50 f/1.2 L, 70-300 f/4-5.6 L IS, 600EX-RT. Sigma 12-24 f/4.5-5.6 EX.
Went to check out the price for rechargeable batteries and this is my shortlist
Eneloop with charger and 4 X 2000 mAh battery @ $59.90
Sony with charger and 4 X 2700 mAh batteries @ $27.90
Which is better value for money? Intending for use with my flash unit. Thank you
a 1000W power supply do not supply 1000W constantly but only the amount demand by the device. a 2700mAh battery do not discharge at 2700mA unless the device demand it. 2700mAh is the discharge capacity, eg. it will discharge at 2700mA for one hour or 1350mA for 2 hours or 675mAh for 4 hours, so on and so forth.
the drawing current will also affect the battery capacity, a Alkaline with 1500mAh rating may fall to half of its capacity in a power hungry device that draw at ~1000mA. for a high power drawing device like flash and digital camera, rechargeable NiMH can be several time more lasting than the Alkaline of equal capacity.
don't take my word, read the article from Energizer, probably the only battery brand that still refuse to produce rechargeable battery.

Hi, i went to the battery yesterday.
Sanyo Eneloop charger with 2 X 2000 mAh battery @ $23.90
Sanyo charger with 2 X 2700 mAh battery @ $21.90
i found that Eneloop battery is only 2000 mAh,
but without Eneloop battery is 2700 mAh.
so eventually i got the 2700 mAH.
can someone tell me what is this 2 different?
is the more mAh can result more shoot and last longer?
Eneloop ones keep charge longer. So you can charge them, put them aside and use them say a few week later and they still retain charge.
Non-eneloop ones do not keep charge long, so after one week you could lose say, 10-20% of the battery life. The non-eneloop ones usually come with higher capacity and last longer when fully charged.
You can find more detailed info here:
LSD battery. if you used your equipment frequently and need to charge the batteries weekly, the normal 2700mAh is a better choice than eneloop.
as you can see from this eneloop review, the 2500mAh retain higher capacity unless they are placed idle over 3 weeks.
most photog use 2700mAh cause they give more juice and reserved the eneloop for backup.
AA/AAA NiMH battery can be charge by any AA/AAA NiMH charger.
The battery charger manual didn't tell me what is the correct way to charge my battery.
should i only charge my battery when it is fully discharged?
or it can be charged after every event shooting?
which is the behavior which photographer will normally do?
Energizer Rechargeable Batteries AA 2450MAH OR AAA 900MAH .
Because my customer use.and the buy for me .
$15.00 per pack (4pcs/pack)
Maha and PowerEx 2700 mAh. You won't regret it.
