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.

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.

Absolutely great, just what I needed!

Works. Better than the old dead one. Fit perfectly

This aftermarket battery surprised me. Unlike many aftermarket products this one came packaged very well but more importantly it seems to charge and hold a charge very well. My initial charge gave me over 4 hours on the battery.

In the first couple of weeks, the battery worked fine. Then, last night, in just a little over a month since I purchased it, the battery will not hold a charge. Unfortunately, I missed the return window by 6 days and will have to take this purchase on the chin. Buyers beware!

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.

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.
