Did not last
The battery price was good, as was the time it powered the tool I used it with ( a string trimmer) but it failed after 2-1/2 seasons of occasional use.

Battery for snowblower
Great battery! The bad part is it would have been WONDERFUL if you had the charger that fits this battery on the same page. We ordered the wrong one first and had to return it. The second one was the correct fit. All good.

Company treated me well.
The battery worked fantastic. Nice long battery life. Stopped working a month later during a project with heavy load, but the company refunded me which was nice.

Great value!
We just got this today but so far item delivered as described, came nearly fully charged, and worked perfectly in our Ryobi trimmer. Can't speak for lifetime of the battery yet as we just got it. So far we are VERY pleased with our purchase!

Not able to review performance.
Battery fully charges. It didn't seem to fit well in string trimmer compartment. Only ran for a short time. Turns outs my Ryobi string trimmer needs to be replaced.

Warranty not available on Chinese product
This battery worked great and was equal in running time to the Ryobi battery that came with my trimmer.However. after 5 re-charges, it will not take a charge. The Ryobi battery and trimmer has a three year warranty for non commercial users. Assumed, this product had same warranty but can find no website for Amityke so am left with a battery that performed less than one year. Amazon should drop manufacturers from China that sell products like this

Replacement at a fraction of the cost
Exact replacement Part at a fraction of the cost of oem. I was able to complete my yard work with one battery on one charge. Only time will tell how the longevity will last.

Worked great for short time.
Original battery is 3 years old and still going fine. This was just a back so I could switch battery out and keep going Lasted 7 months on half use
