    So i ordered this on July 3rd and after a few delays i finally got it on July 15th.. Id like to state that this in no way or means is the fault of the seller. Anyway the battery came neatly and securely packaged and was a breeze to install on my Dell Inspiron 15 3537 computer. The battery was flawless and powered up my laptop after months without a battery. I would like to also state the seller had contacted me by email (before the battery arrived, to see how it worked out and to offer any assistance if needed, which is a pleasant surprise and was much appreciated). I would recommend this Seller TCORE for battery replacement if anyone needs it. They are in my opinion one of the best out there.UPDATED REVIEW-After a few months of solid use this battery is no longer working, the funny thing is my computer is telling me that the battery is healthy and has a full charge but when I unplug it from my computer it shuts down. I've tried everything possible to remedy the situation but I get the same result, I've was going to contact the seller but it's already past the return window. So my suggestion is to go buy a genuine Dell battery from the manufacturer and skip this product
    My old battery had been dead so long that if my Dell laptop came unplugged for more than 1 minute, the computer shut down and I lost whatever I was working on. I lived with that risk for years. One day I just decided to see how much it would cost to replace it. I looked first at the Dell website (hugely expensive), then surfed around on Amazon until I arrived at this one.I followed all the directions that came with the battery to "prime" it to get maximum life out of it. That is basically charge it and drain it three times with subtle nuances. The laptop now will operate about four and a half hours on a charge. Now I have rediscovered the joy of being able to move around my apartment and even go outside with the computer, which I haven't done in a LONG time.I am happy with this purchase. I think it was worth the money I spent and I would do it again.
    Arrived in great quality and super fast.So far no complaints. As stated by others, it charges super fast and holds charge.Used the calibration methods on Dell for Lithium Ion Batteries;1. Remove the AC adapter from the laptop.2. Turn on the laptop. Allow it to run on battery power until the battery is drained to 40 percent of capacity. Hover your mouse over the battery icon in the lower right corner of your toolbar. This will display how much life the battery still possesses.3. Remove the battery from the laptop. The battery is located on the underside of your computer. Slide the locking mechanism to the side to unlock or release the battery. Once released, the battery will either slide out or can be lifted out of the bay. Store the battery until you are ready to use it.4. Place the battery back into the battery bay when you are ready to use it.5. Plug the AC adapter into the side of the laptop. Allow the adapter to fully charge the battery prior to use.
