357F9 71JF4 Laptop Battery Compatible with Dell Inspiron 15 7000 Gaming 7559 7557 7567 7566 7759 INS15PD Series 15-7559 0GFJ6 P57F 071JF4 0357F9 11.1V 74Wh 6333mAh

Swapping the old battery with a new one took 5 minutes and the results were immediate and awesome. It seems to be a genuine Dell battery too. Perfect fit, and the laptop immediately realized the battery was new and ran a self-calibration on it. On a different note, the vendor supplies four little screwdrivers to help you make the swap. That was certainly a nice touch, but none of them fit the tiny screws holding my battery down. No matter. I had the right one so it wasn't a problem. Just be aware you may need to bring your own tools. Overall I'm very pleased! 5 stars.

Have had this almost a month now and still working well. Not as long of a charge as the brand new Dell battery but can last >3 hrs with low energy usage. The only negative is that it definitely heats up more than the original battery (as a few other reviewers have noted), potentially due to the slightly different voltage. On the whole, if you've got an older laptop and are looking to get another 1-2 yrs of useful life out of it, this is a reasonable choice and much cheaper than the OEM replacement battery.

It was easy to install. Good battery life. Good value. Definitely a good replacement battery for my dell inspirion 7559.

This battery fit perfectly. I followed the instructions to activate the lithium battery the first few charges and working like a charm. Thank you! I can now work on my laptop just using the battery.

Fit perfect, and My old 7559 has a new life. update: The bad, it start swallow after about a year, still hold a charge, but I have to take it out. Knock 1 star off.

The battery I received was a brand new condition battery at 99.9% health (measured capacity÷design capacity). Not an official DELL battery (no branding, just generic sticker). Tool kit was useless, it had a Philips, hex, tri-wing, and apple 5 point. None of them fit the screws I had. That being said, definitely a good buy. UPDATE: After 1 month, the capacity had dropped to 85.7% health, or 63.47/73.993 Wh. Despite maintaining good charging habits. Next time, I think I might just fork up the money to get an official DELL battery and not some cheap knock-off.

I have a Dell 7566, which has been used for two years. When I think he can't use it, I am going to replace it with an original battery. The new battery allows me to work all the way to the end. This is a good experience. So far, no other bad problems have been found.

Installed this battery at the end of november and my laptop was running great again. As of today, my computer tells me it has a 58% charge, but my battery analytic app tells me that the battery itself isn't taking a charge anymore. The moment I unplug my wall charger too, the computer dies instantly. Plug it back in, and my computer boots in BIOS mode saying that the battery has completely failed and needs replacement. Sooooo, I'm off to find another battery from somewhere else.

Installed and now can get as good as any other laptop I've owned charge out of it. No issues.

Easy install. Battery required full discharge and full charge before it worked properly. Time will tell if the battery lasts.

With normal everyday use (taking measures SPECIFICALLY to prolong long-term battery life), one of the cells began swelling less than a year after purchase. Battery health still showed up as 90% (using BatteryInfoView), but obviously if left alone, the swelling would continue to get worse and worse, eventually destroying the battery and creating a fire hazard. Since the battery showed swelling less than a year after purchase, I emailed the supplier regarding a replacement (they state very clearly warranty is one year). They did not reply to my email (even though they state that they reply within 24 hours on the warranty card/book). I sent a follow up a week later, and they didn't reply to that one either. Overall, while using the battery for the first few months, it worked as expected: Comparable battery life to OEM, battery monitoring software (including the dell power manager) had no problems with it, etc. But considering this swelling, it is clear that there are quality control issues and the company clearly does NOT uphold their warranty policy. Be prepared for quality concern issues to arise if you purchase this battery.

Replaced the old battery with the new one supplied and computer fired right up. No problems with new battery life after a month

I have bought 5 different batteries, but only this one is working properly.
