Worked out well.

great product, fit perfect, works for 8 hours w/o charging with video playing

I was a bit leery of an aftermarket battery for my 10-year-old Lenovo Y500, but where else was I going to find a battery for a 10-year-old laptop? So I decided to trust the reviews of this one (to say nothing of the very reasonable price) and give this one a try. And all in all, I have to say I'm quite pleased with it! It hasn't given me any problems, holds a charge well, and provides good battery life for the laptop. It's not quite as good as the battery life provided by the original battery (a bit over two hours on a full charge), but that doesn't bother me at all. Anything more than a few minutes is a boon at this point given how old my machine is. So an excellent product and one that I can recommend at least at first use. If it gives me problems later on, I'll update this review but right now I don't anticipate any such problems.

This battery is perfectly fine for the price. It's not perfect or as good as the OEM but it's cheap and works well and has thus far been exactly what I thought it would be. I recommend it. Read the pro-tip below to understand some of the negative reviews to make your own informed decision. Pro-tip: Many of the bad reviews revolve around the battery reporting back at 71 watt-hours. Coincidentally, this exactly what the 45N1001 battery is rated for.... BUT, there is a caveat. This battery isn't actually a 45N1001 it is just reporting itself as one. Heck, it is an aftermarket part not made by Lenovo obviously. Modern batteries for laptops have firmware or certain characteristics that present itself to the operating system as a certain kind of battery. The group who made this aftermarket battery copied a 45N1001 but gave it more capacity. The operating system says "This battery is a 45N1001 and therefore it's rated capacity is 71 watt-hours". There were many versions of this battery, the 45N1000, the 45N1005 etc. Some were 57 watt-hours, some were 94 watt hours, others were 71, others still were 91 watt-hours etc. The 45N1001 was the very first version of the extended battery that worked with every version of the laptop that accepted this kind of battery. Look just how many models this thing works for. Also note, the battery says 70++. That isn't an accident. That is 70+ Watt-hours, which this battery is. The people who mention it isn't 94 watt-hours are right, and may have a legit complaint with the wording for sure, but anyone who knows how these batteries work realize that 94 watt-hours is pie in the sky even directly from Lenovo when these laptops were new. Basically it's letting you know that this works for any of the versions from 71-94 Watt-hours. BOTTOM LINE: SO WHAT EXACTLY IS THIS BATTERY THEN? I'M SO CONFUSED! -- Good me too, but after doing research and real world testing I can report this battery is mostly equivalent to the 45N1007 (even though it reports to the OS as a 45N1001 which is needed to keep the battery compatible across all firmware and all models). The actual watt-hours after 5 tests, tested out to be just under 84 watt-hours which matches the 45N1007 spec of 84.24, which given temperature variations and discharge rate etc. is right there. You are getting an 84.24 Watt-hour battery, not a 71WH or 94WH. For this price it's worth it. As a final note: There may be some people who did get a bad battery or it tested out to be 71 WH in which case I'd be peeved, but what it reports to the OS is meaningless, what it can actually do is what matters. The best I can ever remember seeing out of these things straight from Lenovo was around 90WH IIRC so I'm fine with 84.

Needed a new battery with the 70+ rating for the Lenovo W530 laptop I have. This was very cheap in comparison to the battery from Lenovo direct, yet works just as well so far. I haven't had the battery for too long, so I cannot comment on battery life in how long the battery will last in terms of total usable life. But the charge for the battery seems to be as good as the Lenovo direct battery. I am running the W530 on Mint Linux and use the machine every day. I haven't run the battery completely down, yet. But am testing this now and will update when I can (the Mint Linux OS battery meter indicates a little over 4 hours, which I believe is accurate). I get no crazy notices saying that this is a 3rd party battery and not charge properly, so that is a major difference I see from other non-official batteries being offered. If I can, I will update this review with a long term update to let everyone know if anything changes.

I've only used this battery 1 time, upon complete discharge(from the 63% battery life it came with, to recharging it completely. Therefore this review will be kind of biased, and I will update after using it several more times. HOWEVER, based on my experience, it seems to have a little more time than OEM! I don't remember my laptop lasting as long as this battery at 63ish %. FYI my laptop is the higher end Y510P with quad core i7-4700mq processor, 16GB ram, 1tb HD with 24gb ssd. Will update with more battery specifics after I use it more often. Am excited bcuz first impressions were really good. Update: Disappointed with performance. 5 stars to 2 stars I kept it at 2 stars because at least the battery still works and last long. However, I realized that the battery was nowhere close to the OEM at performance. I used my OEM battery way more than this spare, so bylaw the OEM should be dying out. I don't find this to be the case. FYI, I purchased my laptop on Nov 2013. I purchased this battery on Oct 23, 2016, and it was $49.99 at that time! I still don't think the current $35.99 is worth it. The performance decline is very noticeable, around 25%. That is ALOT, considering I watch YouTube and edit videos. It is 10.8V compatible, yes, but I don't think it's pulling even 9V out of this thing. All in all, if you don't care about performance, this is the battery for you. It will last, but expect a slower performing laptop due to its inability to provide 10.8V.

Received quickly, great price works as expected

Battery died after 2 months. These are definitely not new batteries being sold and this product needs to be delisted.

Cette batterie est 100% compatible pour les lenovo W530. Autonomie d'environ 4h comme à l'origine

Der Akku wurde zunächst als fehlerhaft vermutet, da mein altes, geklontes Windows‑System Kernel‑ und ACPI‑Fehler erzeugte. Nach einer vollständigen Neuinstallation von Windows 10 zeigt sich, dass der Kyuer‑Akku technisch einwandfrei arbeitet. Die Elektronik kommuniziert korrekt mit dem ThinkPad T430, die Kapazität liegt bei 99 %, der Ladecontroller liefert stabile Werte und es treten keine Kernel‑Power‑ oder ACPI‑Fehler mehr auf. Die zuvor beobachteten Probleme waren systembedingt und nicht auf den Akku zurückzuführen.
