It fit my computer perfectly and was really easy to replace. I have it les then a week but for now is working better than expected. No issues at all, keeps the charge for a long time. I have not drained even half way yet and I use it a lot yes I do charge it every night after I use it during the day but I have not yet seen it yet less than half way charge. It is working awesome for me thst I work outside and need a battery that last.Shipping was super fast, Overnight and I was able to use it that same day.I have not have it long enough to say that it will last thst way for Ling time but judging by the packaging and presentation of the battery, I'm really sure it will last, seems like a great quality and almost identical to the factory one but higher capacity. Meet and surpass my expectations. Great product for what I can tell.

Took a chance, as we all do, and this one is a winner so far. About a month in and my Dell Latitude went from around 4 hours to a solid 9+. A total win! We'll see how long it lasts and update when it starts to degrade.

Battery does not charged. Ordered five of these and 2/5 do not charge. :-(

After initially working for about 3 months, but...It was working fine for about 3 weeks. After that time I noticed my laptop did not want to start once on battery only. I was thinking it was my old laptop. It was not. I just bought a new one and all is working ok, but it's the first day. The progressive failure of that battery looked like this:First about 3+ weeks it stopped starting from battery. Once started on AC power it was keeping the load to about 30%. After the next couple of week, it started to die on 40/50/75 and now on 99%. Every time it was worse and every time one "fully charged" system was showing 100% load. I believe something smart is on the battery power board, but I do not have a prove.Solution.1) Be sure when you buy this battery from Amazon it is returnable for 30 days, according to Amazon policy. If the seller is not affiliated with Amazon, you will have to deal with the seller and will be left at his mercy.2) If the battery starts behaving like the above and you still have time to return it to Amazon do it immediately. Do not wait.3) Buy a new battery on Amazon again.I believe if all of us will start doing it the quality of replacement batteries will improve drastically!I'm not expecting miracles, however, I would expect the replacement battery to last at least one Year, for my money!

Love everything about ZTHY TECH INC. The shipping is fast, usually arrives for us in 2-3 days. Most OEM parts take us 5-8 weeks sometimes so this is always reliable. The laptop batter I purchased works for the Dell Latitude 5590 perfectly. The battery does not come with a cable but most don't, not an issue at all as the previous one works perfect. The battery comes in a nicely designed box and packaging is always perfect. Love the addition of the 2 screw drivers and screw that come with it. OEM parts usually are just the part itself. Keep up the good work. I will always order laptop batteries from you guys! Thanks again!

No install problems. Just unscrew a few screws. Unplug old, plug in new

I've had this battery for over a month and it's been great! I followed the instructions on letting it drain, then charging to 95%, then letting the battery cycle 3 times, and although it was a bit of pain at first, the battery is fantastic now. I used to have to charge my abytery after 4 hours of use during my college courses, but now I can get a few days of regular use before it needs charged!The installation is easy enough. The hardest part was getting the power cable off the old battery and onto this one. If they included a cable attached to the battery, it'd be 5 stars.

This is my 2nd battery replacement and these batteries fit and work perfectly.
