Summary: Batteries of this type tend to be expensive and so it is tempting to try the generic ones as alternatives. However, there is NO comparison. The Pentax battery does everything it should, charges well, and holds it's charge, giving complete confidence in the field. All of the generics I have tried are very inferior and simply do not hold a charge for very long. The old adage 'buy cheap, buy twice' sums it all up.
Pros: Easy to Install, Fast Recharge, Long-Lasting, Reliable, Solid Construction
Summary: Bought this one as a spare for a two week holiday. Took hundreds of photos and record a few short vids but never needed to use it.Hold their charge well but take a long time to charge from flat.Was thinking of getting a battery grip but cannot justify one now.
Pros: Easy to Install, Long-Lasting, Solid Construction
Summary: Impossible d'avoir un tel appareil sans une deuxième batterie ! Je vis dans un pays tropical et la chaleur décharge très vite batterie et toute sorte d'accu. Mais là... rien à redire !! Super. Question livraison, rapide et fiable comme d'hab !
