1 Longest Lasting Battery I've Used!!!
Don't be disappointed because this isn't a lithium ion battery. This battery kicks butt!! It lasted me 3 days of non stop shooting. I started to think that the battery was never going to die! Of course reality set in and had to eventually charge it, but it lasted forever!! The only drawback is that it takes about 2 hours to charge:( Other than that, it will lasts you all day and night.
