Yesterday I also bought new batteries and charger for my Canon Speedlite. I chose Sanyo Eneloop AA batteries. It has been proved in quality & durability. My friend has compared Eneloop with other brand, you can read his review here. I’ve also used this brand on my pocket. Since 2008 until now, Eneloop batteries on my Nikon Coolpix L14 still perform excellent power.
My Canon Speedlite uses 4 AA batteries. So I bought 4 plus the big charger. Despite I’ve Eneloop charger, my old charger only has 2 compartment. So to charge 4 AA batteries, I must do it twice in a row 🙁 To avoid that, I choose the charger with 4 compartment like you see at the picture. The charger is fast when perform its jobs. Highly recommend gadget.
