This battery is a bit thinner than the original but tech moves forward every day. Plugged this in, charged it over night. The next day it started up just fine showing full charge. Over the weekend I left the PC in a sleep mode where it would turn right on when opening the lid but not plugged in. Without much use it went three days before going below 85%. If it will perform this well for even a year it will have been worth it. edit Fed 2026 The battery is still holding charge and working well. It has developed an issue where it doesn't show 100% charged, only 99% but have seen no other changes in performance or time off mains. I still consider this a solid purchase.

Battery fits my Dell laptop and fires it right up. Replacement was simple. Not sure how long it will last yet but we shall see.

Delivery was fast and the product was a perfect fit for the laptop. Installation took less than a minute and the laptop fired up. Battery is holding an excellant charge as well.

Works really good. However battery doesn't last as long as I thought it would.

Much easier to install than I expected .Works great.

This humidifier works really well and is perfect for a bedroom. It runs very quietly, which is great for sleeping, and the mist output is consistent without being too strong. The water tank lasts a long time, so I don’t have to refill it often. It’s easy to use and clean, and I’ve noticed a big difference in the air quality no more dryness. Overall, great value and highly recommend!

I followed the "break-in" instructions well enough for the drain time to not be so drastic but it is. It charges quick enough - about normal I'd say..but the charge doesn't last as long as it should and sometimes it'll be at 40-50% one minute and then just shut off the next so it's not reliable at all as far as being able to go off of what the laptop says as time left. Also after it's been sitting a while- like about a week(even if it was 100% when I shut down) it will be completely dead when I try to turn it back on without being plugged in. I also have to use a piece of tape to keep the battery from wiggling out of place and shutting the laptop down while it's in use. Not any better then the one I bought this one to replace. Don't know if I got a defective battery but this one is not worth what I paid- the quality is not good at all.

The battery fit perfectly. The capacity is a small fraction of the original when it was new, which was at least 8 hours. This battery lasts only about 1.5 hours. It's better than the old battery which was completely worn out, but I do wish it had more capacity.
