Panasonic DMW-BLC12 Lithium Ion Battery

Finally, a battery that charges fast and holds the charge for weeks. I've been using it in my camera for daily shots and haven't noticed any power drop-off at all. The lack of memory effect is a real plus for someone like me who tops off at random intervals.

Was a bit worried about third-party compatibility, but this one fires up my camera just like the original. It's held its charge for weeks while sitting in my bag too.

Charged it fully before a long shoot and it powered my camera all day without a hiccup—the lack of memory effect is a real plus since I top it off randomly. Tiny and light, barely adds any weight to the bag.
