My Nokia cell phone is 5 years old and still works good, but the battery life has been steadily getting worse, so I decided to go with a new battery instead of a much more expensive new phone. So here is what I know about trying to make sure you get a new battery and not some old used piece of crap.1)If you dont want to spend around $10 for a new battery you dont have to continue to read this review.2)there are 3 listings for this battery on amazon. one has about 30 reviews, the next has about 16 reviews and the third has about 5 reviews. the first listing with 30 reviews has a battery failure rate at about 33 percent. the second listing with 16 reviews has a battery failure rate at about 50 percent, and the third listing has only one 2 star rating out of 5 reveiews.3) now the prices, the listing with 30 reciews has a price range between $5.53 and $9.19, the second listing with 16 reviews has a price range between $6.67 and $9.19 and the third listing with 5 reviews has a price range between $7.98 to $14.08.4) I paid $10.68 for my battery when the retail price in stores ranges from $18 to $30, so its still a better deal on amazon, and my battery was listed as "brand new in retail package"(sold by CCM ACCESSORIES)and when i received the battery, it was UN-OPENED in a "Nokia Original accessories" package. besides the original nokia package, how else do i know this battery is new? If you look at the pictures of the batteries listed, they all say made in japan, my original battery says "made in china" and the brand new battery i received is also made in china, i cant get any original than that...5)so once again the old saying that says, "you only get what you pay for" works out again, you maybe able to order a cheaper battery, and it may work great, but you run the risk of having it fail, like all those bad reviews you can read about...So far my battery is working really good...........
