Bottom line, I bought one and the light doesn't change when fully charged. Exchanged it and the new one has the same issue. Garbage.

UPDATE:
3rd one was fine. I realized the first 2 had faulty contacts. There are 2 metal prongs that make contact with the battery and they were not protruding properly.

These (I guess) after market batteries are just plain garbage and an awful waste of resources. Don't buy. I bought two. The first never charged and I returned it for full refund. The second worked for a few weeks but now only charges to ~50% capacity, with further decreasing tendency. And I didn't even use it much. The rubber foot attached to it (to become one of the laptops rubber feet) fell off immediately when I first unpacked it. I am contemplating to dispose of it for fear that one day it might cause damage to the laptop. Awful junk. Should be taken off the market immediately.

We've owned this 10 month's. After 6 months the battery no longer charges the thing and when you go to use it the charge lasts less than 5 seconds

I hate that I wasted my money on such a product and there's no way to get it back it's so wrong

Edit #2: new battery and old do not charge. I give up. They charge between 80%-100 but I can't get it to charge again.
Edit: the company contacted me and sent me a new battery that is bigger and better! It works great!

This charges ok but I don't even get a full charge off the battery. Ok in an emergency but I have bought others that give me at least 1 full battery charge. Would not buy again

After charging battery for 5 hours, it only last 7-10 minutes ... We thought the first one we got was damaged, we exchanged it for another one, same exact thing ... Rerunning  and Moving on ...

This is my updated review of the battery:

After posting my first review Anker reached out to me and had the battery replaced. The new one does work better than the first I received, but is still not that great when is comes to battery life. Anker's customer service is A1.

July 1: 2nd Update: The battery barely lasts an hour with no programs running.

These batteries are junk! They must be refurbished. I ordered one and when I plugged it into the charger it showed that it was ready to use, after a few minutes it showed it was fully charged. My kids used it and it lasted a few minutes before dying. So I thought maybe the charger was bad and bought just a regular charger. Same thing after charging it 18 hours. Amazon sent me a replacement battery..... Same exact problem. Only that battery will last close to an hour. So I requested a refund. Both of those batteries were marked with an expiration date of March 2017.
The original battery that came with our power wheel would last for days on one charge, with the kids driving it several hours per day. It one lasted about 5 years too!

I was disappointed and got the bad experience with this order. After a month of using, the capacity of the battery is getting lower and lower,  I just can use it 20 hours for one charge ( including 8 hours of sleeping time that I don't touch the phone ). The factory battery I can use more than 26 hours after charging !
