Nokia BL-5CT Compatible Rechargeable Li-ion Battery (3.7V 1050mAh)

Pros: It works just like a battery should work. It charges fast, and lasts long. I have a Nokia, with a older 'BL4CT' battery, but this one works too (is something thicker, but it fits anyway), and even lasts longer!
Never had a problem, and works as long as today. It even has that holographic sticker, which is just like the real battery! Looks just the same, same text, same cover, and even the same package!

Cons: The black ink on top, and on the bottom is disappearing a little. I think this is caused by the usage of my phone.
Also, it can sometimes have a bad contact with the phone when charging. This is caused by the pins inside the contacts: they are smaller than normal.

Other: If you need a battery, which last very long and costs as much as a coffee: you must buy this one.

Pros: This is a real good option for your Nokia handset. For this price it is really an unbeatable option compared to other options. It feals,it looks and it works like the real thing!!!! I really recommend it!!!

Cons: No Cons!!! No Cons!!! No Cons!!! For this price this battery is really worth the money.

Other: If you own a Nokia handset where the battery is at its end, this good replacement battery will give it a new life. If you buy it you wont regret it!!!

Pros: It's cheap and it works fine - I'm using it with Nokia C6-01 and it looks almost as original. It fits well and charging time is the same. I think this is the best deal comparing price.

Cons: It's 4-5 less durable comparing to my 1 year old original battery. It drains really fast when get to 10% of its capacity.

Other: Good as backup battery, when u need urgently need to replace battery, so it's OK purchase overall.
