I bought this Replacement Laptop Battery for my Lenovo ThinkPad, and overall, it has been a solid purchase. The battery fit perfectly and was easy to install. Right out of the box, it held a decent charge, and after a few cycles, it reached its full capacity.The battery life is good—not quite as long-lasting as the original, but it gets the job done for everyday use. I can get around 3-4 hours on a full charge, depending on what I’m doing. For the price, I think it’s a great alternative to an expensive OEM battery.My only minor complaint is that it took a little longer to fully charge compared to my previous battery. Other than that, I’m happy with the purchase and would recommend it to anyone needing a budget-friendly replacement.

My good old comp (hand me down from my son's college years) was not doing too well lately - no wonder for a 13 years old poor thing. I did't do anything serious on it, just some record keeping, recipes, gardening, Pinterest, odds and ends, although I did some R programming and data mining, and it rose to the occasion. When it finally refused to power up one day I was upset - it was like a loyal pet: great companion, never gave me any troubles. On one hand I knew it was approaching its end, on the other hand I was willing to try a final resuscitation before letting it go. So, I bought a new computer and ordered a new battery (and a new power cord) for my dying one. To make the story short, replacing the battery was piece of cake, my darling comp came back to life, and I am looking forward to living with it happily ever after. It's a Lenovo L412, great machine.Gave the new computer to my son, never even looked at it.

Works as expected.

I received the battery. I plugged it in to charge it, but when I turned the laptop on it still was dead. Could be something else wrong with the laptop, I am not sure. But I still can not use the laptop. Any idea of what might be wrong with it. Any assistance would be appreciated. The battery might be good, and something else wrong with the laptop.

It fits. The price is right. When one has limped for years, yes years, having to keep the laptop plugged in to use, even a low capacity battery is better than none. But I have only had this one for a month and there is no reason to say it is low capacity. The fact that I can go 2 hours or more without AC is so much better than the 2 minutes I had with the old one. I was asked by Amazon to rate 'sheerness' Well the fact that Amazon asked that, well that is sheer stupidity.

Battery didn't last 4 months. It will not hold a charge anymore. Unfortunately with the age of my laptop it's hard to find legit batteries for it, but this battery is very cheaply made. I do not reccomend.

I've had this battery almost a year and it's still working good. I get several hours of run time and it charges fast. great battery for the price.

good prices, good quality. It works, and keeps the computer running for up to 5 hours.
