Reliable Replacement Battery for My ThinkPad – Great Value!
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.

Battery failed in a little over a month
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!

Aftermarket Lenovo Battery
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.

Hey, it's a good battery
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.
