Rated 5 out of 5 by from The Worse Battery Life for any Laptop EverSame experience as everyone else. The battery holds a charge for about 30-45 minutes before dying. This began just a little over 12 months. I'm not a heavy user either. Very disappointed. Wish there was another option as I don't want to purchase another one only to have it die too.

Rated 5 out of 5 by from Still at 40% capacity after 5 yearsAfter 5 years of daily use (6-10h) with partially-on-ac and partially-on-battery, the battery reports ("upower -d" in Linux): energy-full: 33.6 Wh energy-full-design: 84.3 Wh which means it has about 40% left of original capacity when fully charged. At 4 years it was 53% of original. I can still use it for an hour or so at moderate usage on battery. Many others have reported they can no longer use it without charger (at about same age), but they have used it almost completely on ac so the battery clearly detoriates faster when at 100% charge most of the time.

Rated 5 out of 5 by from 1 year Battery LifeI had my brand new Thinkpad and after 1 year the battery doesn't hold a charge anymore. They still have this for sale after all the bad reviews? I wonder why they don't fix this problem.

Rated 5 out of 5 by from ExcellentReceived the battery and dropped it directly into my laptop. Even though I had never changed a battery before in a laptop, found it was super simple following the directions. Worked with no problem and has kept on working now for several months with no problem.

Rated 5 out of 5 by from Long lifetime here (but hardly use battery)I have a lenovo thinkpad T520 with a 9 cell 55++ battery since 2010 - so for 7 years now with nearly daily use. But 97% i am plugged in but battery is always in. I had around 50 full load cycles due to BMS and battery capacity is still at around 97%, due to batterie-monitor (batmon.exe). So the lifespan is really amazing to me, when you dont push the battery too hard. Never let it go down to 5% capacity or lower (but i guess i even did this a few times in the beginning).Notebook runs on battery for around 3 hours still with midium load.

Rated 5 out of 5 by from Excellent Value!Don't be fooled by knock off batteries that are cheaper, you get what you pay for with a Lenovo replacement battery. Our original battery lasted almost three years with daily use. The new one appears to be faster charging as well which is a big plus since we run on battery exclusively. Don't set yourself up for disappointment in a few months with a inexpensive battery that won't hold it charge! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from It’s WELL worth it.This battery revived my favorite laptop ever...the T430. Prior to this battery, I bought a no-name version that lasted about 3 months and never achieved more than 4 hours max life on a good day. Now, with the OEM battery, I’m confident I got what I paid for as evidence of the 9-10 hours of battery life now. Now, I can leave the charger in the bag while I’m at work...money well spent.

Rated 5 out of 5 by from Good batteryIt's a good battery. My old battery was the smaller one, purchased 12/2013, and for the first time I was in a position to need battery power. The old battery was on its last legs and I wanted the larger capacity anyway. Happy with the results.

Rated 5 out of 5 by from Love the 9cell battery!!!In our company we use laptops all day everyday. Having a battery you can trust is a must . I have been getting these Batteries for the Past two years and the 70 ++ has been the one I turn to the 9Cell extended life keeps my guys working not plugged in charging there batteries. that extra life is the difference in getting the job done or having to come back after a recharge.

Rated 5 out of 5 by from A little to early to tellIt's hard to review a battery before I know how long it will last. My Thinkpad 430 has been getting very hot at the battery site. I'm not sure if it's the battery or the laptop.

Rated 5 out of 5 by from Weakpoint of LaptopI'm on my second 70++ battery. First one lost it's charge capacity over a couple of I years. I bought a replacement and after 1 year and 3 months the battery suddenly died and is outputting 0V. They are very expensive and it seems like it's a bit of a gamble if you get one which is decent or not. Overall it's quite a design flaw in the Thinkpads having such unreliable batteries and is making me other laptops when we buy replacements.

Rated 5 out of 5 by from (used to be?) greatI had mine for 5 years and it was awesome. I could work about 8 hour every day. But lately it went wrong and now I can work for about 1 hour. The change was VERY rapid. I thought I would buy another one but after reading recent comments I'm not sure it's worth the money.

Rated 5 out of 5 by from A 1 year affairLike others have said, battery is strong and good for about a year. It degrades pretty quickly after about 13 months of normal use.For the price, this product is not worth it for just a year of optimal usage.

Rated 5 out of 5 by from Value for $$? Not there at all.I'm on my third battery - second replacement. At 12 months, battery performance drops to less than 25 percent. At 15 months, the battery is useless. T530 laptop and I do all I can to conserve power all the time. At $160 plus shipping, that's over $12 a month for this battery. I will be talking hard to the IT team about upgrading my team's needs to something more adequate as these T530s are costing my budget roughly $3500 a year. A laptop shouldn't have to be upgraded after two years but when you add 20 % of the laptop price to two batteries in two years, the machine is no longer the bargain Lenovo sold it for. Even if you follow all the battery-power conservation advice, the bottom line is the battery is the weakpoint in all Lenovo products. Add 20% of your deployment costs in additional yearly maintenance if you consider Lenovo ThinkPads

Rated 5 out of 5 by from Great, but then no so goodWhen brand new, this could power a W520 Thinkpad (a beast of a machine) for 8 hours of solid activity (max brightness, WiFi/Bluetooth on, some optical drive usage, near constant HD thrashing, 32GB RAM, average 50% CPU) throughout the workday.Fast forward 2 years, and daily cycling the battery power from 100 to 0 and back, and this same battery barely lasts 2hrs with less than half the load (~30% brightness, WiFi on, bluetooth off, no optical usage, sparing HD, 16GB RAM, avg 25% cpu), which is disappointing.

Rated 5 out of 5 by from works jes finewell packaged, fit easily although extends beyond the case, charged normally, and provides at least 4 hours of battery life. The old bettery had perhaps 20 minutes of charge. So, i am pleased.
