As luck would have it, I finally was able to get a spare lithium battery for my reliable VG-110 camera at SM ANNEX in SM City, Q.C. today! The price was a stunning P610, way below the official battery sold at P1,960 pesos in other camera shops!
You may be able to get one, I wanted to buy two at Battery channel, 5th floor. I will visit it again to see if there is another one available. The Battery Channel even gives a three months warranty for the sold battery.
I am satisfied with the quality so far.
