Olympus Third Party Battery - BLS-1

Purchased this additional battery from Ebay and as it is very cheap, only USD 5.18 including shipping. However, maybe because it is cheap, i actually waited 1 and the half month before i received this item in my mailbox.

Overall the battery is usable. It can be charged using original charger but it seems like the indicator cannot tell when the battery is fully charge as it always shows fully charge after less than 1 hour. As such, i always let it charge much longer. As whether can take more photos, i never take the exact count but i feel like is comparable to the original battery.

Another problem of this third party battery is the size. It is a bit bigger compare to original battery. As such, the first time i try on my camera, the battery actually stuck in the battery compartment, the spring is just not strong enough to eject the battery out. Because of this, i use pen knife to make the battery smaller a bit. It is really ugly but it works. Now the battery can b ejected out without any problem.
