Intro: This battery works much better than the original Lenovo battery ever did; the OEM battery has a well-known design flaw which Lenovo never publicly owned up to, which triggers a protection circuit on the motherboard which in turn requires an odd reset procedure. Once this protection feature is triggered the notebook will shut down randomly, even on AC with the battery removed. I was about to order a new motherboard for my notebook until I came across that anecdote about resetting this fault. I tried the reset procedure and confirmed the issue was the battery monitor PCB, so I left the battery out and searched for a non-Lenovo replacement battery. I was skeptical at first about this battery when I saw the price (it's a nine-cell extended capacity battery) but I decided to give a shot: it couldn't be any worse than the original lenovo battery. BrainyDeal took a couple of days to ship it out (I was shooting for getting it before the weekend) but when it finally arrived I was pleased to see the battery fit well; it's not a perfect fit, and is obviously a reproduction made from making molds from an OEM battery (the seams are a lot more visible), but it fits a heck of a lot better than other third-party batteries I've used in the past - and the OEM Lenovo batteries are so problematic that style is not even a concern. I just want the notebook to run without shutting down randomly, There was a slight charge on the battery when I received it but I did not run it until it charged fully. I then ran it for over two hours once charged (to verify life was decent) and it worked perfectly with kpowersaved (one of Linux's APM/ACPI monitoring/configuration apps) and the battery seems to offer decent battery life. About Lithium-Ion Batteries One is not supposed to deep cycle li-ion batteries often; they have the longest service life when not cycled below 30% charge but I tend to deep cycle them once in a while ; never run down to critically low but a little lower than 30%. The first time I used it as a portable I ran it down to approximately 50% and the life to that point was fairly decent, and I was running a 3D desktop so the discrete video card was working fairly hard at that point. Obviously the extended capacity in this battery lives up to BrainyDeal's promise. Just make sure you at least partially drain the batteries every few days; if even just a few minutes. Continually charging the battery to 100% without ever discharging it will kill the battery just as quickly as deep-cycling it. Also, do not believe the hype about "battery memory" as Lithium-Ion batteries do not exhibit this phenomenon to any noticeable extent. There is no need to drain the battery completely; in fact partial discharges and slow recharges will greatly extend the usable lifetime and capacity of the battery. Fit and finish I mentioned that the shell for this battery appears to be a reproduction unit. What I mean by this is that the shells are not molded from the orginal tooling, but the third-party's mold was probably made from a disassembled production battery. On the mating side of the battery (the connector side which meets the notebook) the fit is tight with no slack, so in that respect it is every bit as good as the Lenovo batteries made from their own tooling. The outside is another matter: the shell is slightly out of alignmnent from the chassis, and the battery seams are more visible than they are on the genuine Lenovo battery. Why choose BrainyDeal over Lenovo? The original Lenovo batteries have unacknowledged design defects. They are faulty from the factory. If you are choosing between more expensive original Lenovo batteries or these cost-effective replacements, take it from me: these generic batteries work better than Lenovo's own batteries. They are well worth the money, and let's face it: your notebook is a tool, not a fashion statement. No one is going to notice the minor flaws in fit-and-finish on the battery, and you will appreciate every moment of extended runtime when you're putting those last-minute touches on your presentation before your plane lands! My Experience to date: * I have cycled it down to 50% or so one time. It takes at least two hours to reach that state, running the compiz-fusion + KDE desktop on OpenSuSE Linux * I have cycled it down to 80% several times * I suspend to RAM very often * Boot-up is the killer: booting up or rebooting will take 2% right off the charge because it is so heavily I/O and CPU intensive. If you are going to be working on the go and dual-book, select your OS and boot up before you unplug, and suspend to RAM. My configuration: Lenovo 3000 N100, type 0768-E7U Core 2 duo, T7200 (2.00Ghz) 120GB HDD (older one, more power hungry than newer drives) 2GB RAM Discrete Nvidia display card So, my notebook is a little bit of a power hog. Swapping out the drive for a newer one would gain additional runtime, as would the 3000 models with integrated Intel video. I have had the battery for several days now and wanted to cycle it the way I normally would prior to writing the review. I am extremely satisfied with this battery.
Customer Review: Cheap Plastic casing but hoping battery will last long...
I just recd battery by UPS ground which was right on time as mentioned on the order. Opened the box and found no certificates as mentioned on the amazon product page. Plastic casing of the battery is little loose and clicking. I am afraid the outer casing might not last long (keeping my fingers crossed). It looks like cheap quality of plastic casing has been used. Hopefully the cells of the battery will last long. I am overall not too happy with the delivered quality as of now. Will update my review after I use this battery for some more days... I am hoping for the best
