Fits perfect and works great!

So far this battery appears to be working. The cost of the battery encouraged me to take a chance. The last battery I purchased on Amazon never held a charge well, but this one came with a 70% charge. I’ve let it complete go deplete the battery three times and it has charged back to 100%. I’m pleased since far.

Works as expected.

As advertised. Thank you!

As the title says, it fit into the computer with no problem and I was pleased to see that it was charged well enough to run the computer right out of the box. Also I was pleased to find that it was being delivered one day sooner than they first said.

Worked great. I installed chrome on this very old laptop, switched the battery, and it ran well. Sold the laptop for more than I could have otherwise.

Perfect for e for my laptop. So far so good 😊👍🏾
