I already have original Nikon batteries for my Nikon Coolpix L2. But I need to buy another pair because you never know when batteries can go down. Can I use Uniross NiMH AA batteries in my Nikon Coolpix L2? Can I charge these batteries with Nikon charger? If not what rechargeable batteries can I use for my Nikon Coolpix L2? Or do I have to only use Nikon batteries for Nikon Coolpix L2? I would really appreciate early response from you guys. Thanks.
