Litheli 20V Battery Pack, 4.0Ah Replacement Lithium Batteries U20 Power Tools and Phone, Tablet, Laptop, etc

It took me a while to figure it out. It's not just a case you can just slide your phone into. It has a plastic insert that you have to take out, take apart, put the phone in, put it back together and then put the whole thing in the case, but after this was put together, it's probably one of the best phone cases I've bought. I like that the on/off button is underneath a tab that you have to lift so you (he) can't accidentally turn the phone off it's very sturdy, for my husband that does construction highly recommend,

These batteries are great. The delivery was very quick and the product was undamaged the batteries last a long time and can also be used to charge other things. I use one of these in my heated vest and it is awesome. It extends the time by three times happy customer.

Have not needed to use the extra battery but it is always nice to have a spare in case something goes wrong. Planning to get another soon as the batteries work best in pairs. I love my new snow blower.

Works great! Got use to timing charge time but it lasts to cut whole yard

Works really well charges up pretty fast and last pretty good so I would recommend it

cost was higher than expected

I like the fact I can utilize the 4.0 along with the 2.0 batteries for the mower I purchased. I like that I can use my phone charger. I dislike having to wait three hours for the battery to charge.

I purchased a extra battery because the one that came with mower doesn't hold charge long at all I don't live on farm land so I feel it's charge should last for front and back yard area and it doesn't was planning on sending it all back but really don't feel like the hassle of putting in car and unloading it but I advise don't purchase it

i ordered 2 batteries, and only 1 came in, so I'm so disappointed with the service, I hope that i get either my money back or get the other battery in soon

Don't bother to buy for extra battery when battery is close to going dead it takes forever to fully charge. Your dead battery will charge faster than this battery!!
