Sanyo eneloop is some awesome tech. They come factory pre-charged and have very low current drain when not used. (They claim 75% of full capacity after 3 years at 20°C. It will be faster in our climate, but still very good compared to conventional NiMH batteries.) They have very low internal resistance too.(good for high current demand devices, like cameras) The charger included is not a fast charger. It charges AA 2000 mah batteries in 12 hours. Slower charging gives batteries a better life. However, if you need to keep charging faster, get a quick charger from somewhere and buy the batteries separately(available on flipkart). I use these batteries on a camera flash (Nissin Di 466 for Canon) and it charges it much faster than duracell alkaline batteries. Btw, you get a charger 4 batteries. This is not mentioned properly here(though shown correctly in the image). The batteries are made in japan while the charger is made in china. Flipkart service was awesome as usual. Quick delivery and great packing.

Sanyo eneloops are LSDs (Low self discharge batteries). It means once you charge them and keep them unused, they hold charge for a long long time in case you dont use them. Also dont be fooled by their low 2000 capacity. A 2500 mah normal non-lsd battery looses charge fast within few days of charge and reach 2000. Note that 2500 mah batteries better if you charge and use the batteries within few days of charging. Else LSDs are a way to go. Hope this helps I got these from amazon a few years back and they rock. I rarely charge them for my use but they are always available with full charge when I need them. Also these batteries have no memory effect which is good.

Comes highly recommended in reviews and doesn't disappoint. Slow charges eneloops for longer life. Charger comes with four batteries. A NiMH or alkaline battery should perform at its Ah rating, with high-drain loads, like flashes, while discharging for the entire discharge duration, though they don't. Eneloops are designed to perform more consistently in such situations.
