Nokia BL-4CT Compatible Rechargeable Li-ion Battery (3.7V 860mAh)

Pros: Works just like the original batter for my phone! Cheaper than buying it from the dealer by like $10.00 USD

Cons: Had to wait 2 weeks for one tiny battery...

Other: Excellent so far! Will update if it stops charging.

Pros: Mighty cheap, if you take 3 or more. Fits fine. Build quality is equal to orignal, except for the hologram, which is about quarter the quality/resolution/effect of original. But, nobody really cares about the hologram, right?

Cons: Very low capacity - I measured only 250-300 mAh when charging to 4.2V.

Other: I needed extra batteries for longer trips without charger. I didn't get exactly what I wished for, but I'm still happy. Even considering the capacity, it's still cheaper than buying original Nokia and if you don't mind swapping the batteries, then it's worth the price.

Pros: Well it looks exactly like my original battery from the manufacturer that ended up failing for some reason and t-mobile won't replace it. I thought that DX would carry it and sure enough they did! So I bought it and about 2 weeks later I received it and was very pleased that it held a charge and worked for the same amount of hours as the original battery. I strongly recommend this battery if you have the nokia

Cons: none other than took so long for shipping. But i can't complain about that really because shipping is free and is in china. I'm in the US

Other: This battery was well worth more than I paid for it. And so far I've had no trouble with it. I've had it over 5 months already.

Pros: Mine came in a "genuine looking" package. Has Nokia designs and logos marked all over the package. The battery itself has all the genuine logos and markings. Looks almost identical to my original battery. Even has the holographic sticker ! ....too bad the battery is NOT genuine though.

Cons: Not too much considering the price even though it's fake.

Other: A good clone for the price, battery life is fairly good compared to a real one. Price is right.

Pros: it's not authentic.
the price is great it costs 6 times less than a replacement, or 10 times less that an original.
it's holds a bit less than the original one. but since i had troubles with my cellphone and didn't know if it the phone or the battery, at this price i could find out.
came in what looked like an original nokia casing - but you could see it's fake. came fully charged.

Cons: i think it's a waste of time to make it look like an original nokia battery, just write it's a replacement and that's it.

Other: good product for this price even great.

Pros: I got one that looked like the original Nokia battery. It even had the Nokia logos.
But that's where the similarities end.

Cons: Battery life is very short. If I take about 5 short calls lasting about 2 minutes each, the charge is gone by the time i get off work at 5pm.

Other: It's cheap, and performs expectedly based on its price.

Pros: Looks identical to the original Nokia battery, even the hologram sticker (altough the picture in the hologram isn't so nice) The capacity is the same as the original battery; my 5110 phone lasts a week before i need to recharge :-)

Cons: None whatsoever.

Other: Buy this one if your old battery is broke! Capacity is OK, fits perfect, and for a unbeatable price !!!

Pros: It extended the life of my old cellphone for 6 months. Enough for me to get some money and buy new one.

Cons: After months of use, it became too hot when charged for long periods of time, and it held little to no charge at all. It seemed kind of dangerous when it got too hot. From what I've seen, I don't think it's an original Nokia battery,

Other: Get it if you cellphone battery is dead and you can't buy a new one for a few months, otherwhise, PASS.

Pros: Looks like an authentic battery, the package and battery has the genuine Nokia logo and works good on my cellphone.

Cons: Battery discharge is really fast, while my old battery lasts for 20 to 24 hours of use, this one holds charge for less than 12h. If you don't have any other battery this is the cheapest replacement ever, but be ready with your charger when you really need you cellphone working.

Other: It's the cheapest option for a nokia battery, but they need to improve the charge capacity
