Received as described. Powered up and drained the battery to test life "out of the box" and provided slightly over 2.5 hours of use.  Have recharged and drain tested again twice and the power holds steady for the same amount of time. There are cheaper batteries listed by other companies, but the inconsistent reviews turned me off.  My last battery was purchased from Dell for over $80 and gave me crappy performance.  So, far, so good with this provider.

I bought 2 of them.  One battery would not charge, and after running a hardware diagnostic I got error: Battery not installed.  When I ran the service tag, Dell claimed it was out of the warranty period.  I called them, and they told me the device had been purchased in April of 2017.  Upon further inspection, there were old shipping labels on the boxes which were indeed from April of 2017.  This is rather unprofessional of the seller.  I am taking no chances and returning both units.

I have had this battery for few months, it works fine.  Shipping is fast, price is good compare to Dell.  I love it.

Avoid this over priced buggy garbage tablet before you learn a 2K lesson like I did.  I should have taken it back a month in when it had flickering screen issues.  Now 6 months into owning it the computer won't charge.  I bought a verified legit Dell power supply from Amazon in a $50 trouble shooting exercise that proved it was the computer not the adapter.  Not sure where I'm going from here, but from a bit of online research I find out I am not unique with this problem for an overpriced buggy pile of crap.  I've owned a lot of computers, but none engineering this poorly by a company that should have the experience to head off such disasters or at least own up and try to repair.

I have had this battery now for about two months.  It snapped right in place into my Dell computer just like the original battery.

This battery is working very well so far.  I love it.  I am glad I could get a replacement for a reasonable price instead of the stupid expensive high prices Dell charges for replacements.

About three weeks ago I purchased one of these batteries for my Dell Inspiron E1705.  I was satisfied with the original computer battery but had always wanted a little more endurance.  I put the New Trent battery through the roughest use I could think of.  I used the Dell "default" power settings, charged the battery fully and used it to watch videos, play games, run diagnostics, surf the web, and download a few things.  Exactly three hours later (OK so it was three hours and three minutes) the seven percent warning on my computer began to flash.  By comparison, the original battery (now about four years old) lasted about one and one-half hours under somewhat lighter use.

I am assuming that this battery is similar to the Dell high capacity battery.  Dell's battery is 80 watt hours, and New Trent's is 7200 milliamp hours (for those of you who don't like comparing apples and oranges, they are roughly equivalent).  Both use nine lithium-ion batteries.  But here's the hitch.  The New Trent is available for $32, but the equivalent Dell retails for $155.

The only problem I found with the New Trent battery is that the fit is a little snug.  It goes in fine, but needs a strong fingernail to remove it.  Fortunately, I don't need to remove the battery very often.

Needless to say I am extremely pleased with this battery.  The Amazon customers seem to agree, with a 5/5 rating.  Compare this to the Dell website's customer satisfaction of 2/5 on their equivalent battery.

I purchased two of these and neither of them were labeled as genuine dell batteries. I'm in the process of testing to see if they function properly.

I bought a battery from a discount battery store and it did not last very long.  I've learned my lesson.

I have a Dell Inspiron 2200 thats probably around 6 years old now.
The original battery died, so I couldn't use the laptop unless it was plugged in. If I unplugged it the laptop would instantly shut down.

I then bought this battery because it was cheap. I popped it in and now I have a real battery in it. It says its got 4 hours remaining on it.

im SO happy to have a batter back in this laptop. I was allmost going to go buy a tablet but I don't need to now.

Received undamaged, but the battery doesn't work at all.  Looks almost identical to the original Dell battery, though this one is lacking a special sticker with a dell part number and a barcode.  Unlike my other two batteries, the laptop indicates that the battery is defective and will not charge.

Reviews are overall fairly good, but after experiencing this problem I read some of the negative reviews and found that others have had this same experience.  Is this really being sold by Dell, or is Amazon mis-reporting the seller?  I looked on the Dell website and they no longer carry this part ... so I think this product is falsely advertised and is not really being sold by Dell, but I'm not sure.

I received this battery to replace the battery of my Toshiba Satellite S850 and my computer immediately told me that the battery I was using was poor. I thought this might be a mistake so I powered off my computer and turn it back on with the battery attach and again I was told the battery was poor. I decided to test the battery myself and even with  power savings on this battery barely last more than an hour and I JUST GOT IT.

This battery came to me in poor quality and I am upset

UPDATED: a couple of months AFTER THIS REVIEW - ZTHY contacted me and provided a free replacement even though it was out of warranty! The new battery seems to have MUCH MORE staying power, I have adjusted the stars to 4. will update in a few months as to longevity. PRIOR I purchased a replacement from another seller, that failed within 14 days - and cost more!

Installed and charged OK January 2017, screen flicker and reboot started August 2017 at 60% drained. Pulled battery and reseated, lasted 5 days before symptoms returned. Now random reboot under CPU intensive browsing (video is impossible) at 25%drained. Using stock charger and cables. Pros. Added life, exceeded 6month description warranty,. Cons-  however honestly rather pathetic performance. Will stretch a few bucks for the next replacement.

I received my battery a few days ago from Power Direct.  Got here in 2 days.  It came 80% charged.  I clicked it into my aging Dell Inspirion 1501.  The fit was a bit snug, but clicked right in.  This battery was a little heavier and larger than the original that died last year.  However, it fit, and the size does not seem to affect anything.  I am holding my full review until the break in (condition) period is over.  The instructions on the back of the battery box state to discharge the battery (use it) then fully charge it.  I am on the third initial cycle.  I have not fully discharged it as it is a Lithium Ion battery and they (I am told), do not required full discharge and recharge to break them in (condition).  My laptop states about 2:30 life while I am using it for picture viewing and editing (pretty good).  Hoping it may go up to 3 hours if all I am doing is web surfing.  So far, so good.

UPDATE: 3 years later the battery is dead.  I used the laptop heavily for a year and then bought another one.  My daughter used it for 6 months and then it sat in a closet until now.  Wiped the computer and fired it up again, Dell inspiron 1501 and the light flashed indicating a bad battery.  Lesson: keep using it or it will malfunction.  Now I will order another, for half the price I paid 3 years ago!  Hope this helps you!

I purchase one of the refurbished DELL Latitude Laptops, D620 and the battery seemed low. It would charge, but I was only able to use it for approximately 40 minutes, then it would die. I emailed the distributor and told him that I thought refurbished meant a new battery, but then I read so many other reviews, of which most of them said the same to me, so I ordred a new battery from Amazon. BUT, the distributor had sent me a new battery also! I thought that was such wonderful customer service! I expected them to ignore me! Now I have 2 new batteries and my refurbished DELL is in great shape and I'd like to thank the distributor!

Battery arrived in good shape.  But the e5440 does not recognize it.  Tested it among 6 units. 1 with bad battery 5 with good ones, all report that same in the BIOS.  I would recommend not using this one for a dell replacement.

When I first plugged in my Vostro 1500 after installing this battery, I noticed the battery light on the right side of the computer was flashing alternatively red and green.  When I pushed the power button to start the computer, the BIOS flashed a message that the battery could not be identified and would not be charged in the system.  I pressed F1 to continue and the computer booted up in Windows XP.  I checked the Power Options in the Control Panel and noted the battery power indicated 52%.  I turned OFF the computer and let it charge for three hours.  After re-starting, I received the same message about the battery not being identified.  I pressed F1 to continue and proceeded to the Power Option to read the battery power; it was still at 52%.  This battery is not compatible with the Dell Vostro 1500.
