Battery was a perfect match for my 10 year old DELL 17" laptop. long battery life and I am very pleased with the battery.

It’s really great when you purchase a needed product from Amazon ! and you get it and it’s so nice that it was exactly what the description said it was my laptop is over 10 years old it said forever that the battery needed to be replaced and of course right in the middle of doing a really big Excel project it shut off black screen !! Got online (phone) and in less than 48 hrs I got this great battery for my favorite old dell laptop and install was real real easy! Having my new battery what a difference my laptop is working like it’s brand new. Charge is lasting as long as it should just thrilled with this battery.

Price, easy install, and the value worth getting!

My wife has a rather old Dell laptop, perhaps circa 2010. My daughter has been using it for e-learning and discovered that the battery (which was the second one for the laptop) did not work, so I ordered this one. Seems to work just fine, at least for now. Batteries like this don't like to stay fully discharged. For the price, we'll see how it goes.

The battery fit my laptop with no issues and my laptop started right up. I'm probably going to keep this as my backup and use it as soon as my original battery fails completely. So far the laptop is telling me that the original battery is holding a full charge but its ending its life span soon. This battery seemed to be fine and should extend the life of my system. Thank you for shipping it out and having it arrive a little earlier than expected. Will most likely be back for a second battery when my original one finally goes.

I have an older Dell studio laptop. This is a replacement battery. This is an older battery it does what I need. It holds a charge and let's me know when to attach my charger. This is functional and will allow me to continue working this laptop.Solice Trading Company was a 5 star transaction. The fulfilled the order timely and with proper packaging.

This is my third Battery for my Dell Studio 1749. The last two were more expensive. They lasted 6 months. I started by draining and fully charging back to back 3X’s. This battery starts out at 6 hours of use time. All options are run at full performance. No battery saving modes here. I like my screen bright, processors fast and memory hogging software. It acts as the acting DVR for my home video and security system. It lasted 4:50 hours of steady heavy use until the UPS Back-Up kicked in. Amazing. I’m very happy with it. I still let it and the battery back-up runndown every Saturday morning. The battery still burns close to 5 hours every drain.

This battery functions reasonably well for an after-market battery. In power save mode, I get at least 2.5-3 hours, which is a lot considering how much of an energy hog this computer is. If not in power save mode, the battery dies fairly quickly. I haven't had a battery in my laptop for quite some time, so it's nice to be able to pick it up and move it.
