Yes, it works fine and is very easy to replace. Battery case comes apart and you can see what to do.

I have no problem at all with this. I use it to keep my spare battery charged.

No, the USB charges the battery and it won't work w/o battery. Although you can work with it while charging, but it is recommended not to do so, to increase the life of your battery.

In my case no, as I bought it "used" w/o batteries. The batteries I had for other tools I owned worked with this item.

The item is not a battery operated unit. It will only function when the power is on. Also, my wife's has died since my original review.

It has my car battery. I ma not a techie on this. I read the reviews from other guys who were a lot smarter than me. I hooked it up and then used it once a week unless I drove the csr that week. It is really working for me.

There is a battery charger within the box that you have to use to recharge the battery.

the item is solar powered. You charge it in light, there is no 'battery', just a capacitor that stores energy.
