I use these batteries in a remote control, the annoying toilet flusher, a portable radio, my owl alerts, flashlights, and many other battery powered gadgets that normally discharge batteries. So far they work really well in these gadgets and the charger surprisingly charges them faster than I thought. Definitely worth the money because they last much longer than the non rechargeable disposable batteries and better for the environment. As for fit they seem to fit fine in everything so far without any problems which is really nice especially on expensive devices. I can tell you that they get a little warmer in the charger than I am comfortable with which concerns me. Because from personal experience fast charging getting batteries hot is not good for any rechargeable batteries it runis them plus its not safe I wish they had a slow or low charging setting. I can honestly say these easily out perform the Rayovac, Energizer, and Duracell rechargable batteries that discarge quickly saving you money and headaches. For just normal homeowners use for remote controls and around the household these should work perfectly fine. I have bought other batteries from EBL off revain and absolutely love them. I will have to keep taking notes on discharge, charging, and start measuring voltage on these to see how consistent they are and update this review. Stay tuned.Truthfully the only reason why I bought these is they do not offer the red EBL 1.5v AA Li-Ion rechargeable 3000mWh batteries in any quantity greater than four with a charger on revain which is why for value for my money I only rate the "value for the money" partpurchase at 3 stars. EBL needs to make those available here just like these batteries why they do not is a mystery to me. If you need an honest to goodness AA 1.5v battery for something sensitive to voltage read my review on those batteries they sell.
