Nikon Battery EN-EL10 is an ultra-compact rechargeable lithium-Ion battery which can be recharged with a specific battery charger The EN-EL10 delivers high performance in a compact package
This battery is precisely the same as the one my Nikon Coolpix camera came with. However when I used this battery straight out of the package, I was able to take 1/3 of the photos I took with my previous battery (before either battery needed charging).
The batteries were as described and were purchased to replace like for like. As with all Kikon branded products they are durable and will last a long time ie multiple charges.
