Replacement battery for NB-4L

okay i'm just showing you my uh spare battery i bought for my canon i bought the unbranded button not the official one i bought this quite cheap it only cost me two pound 80. so if i wanted to buy the official one i would have to pay at 15 pounds for it it doesn't give me as much life as the official one but it's pretty good i think it gives me about half the life of the official one takes the same amount time to charge as well a few people were saying you can't charge this battery in your normal charger but you can i've tried it and you can charge it i think it's pretty good for backup this canon battery works in many different canon cameras there's a full list of them if you're just searching google
