I've had Panasonic phones for 15ish years and the batteries were no longer working as well as they once did. I replaced them with standard AAA batteries (1.5V) and those worked well, but these make more sense to use since they're cheaper than the other batteries and I don't need the extra juice. I'm happy to say these have been working well - charging easily, holding a charge, and keeping my phone working well.

These work excellent in remotes, and should last years. Just recharging and using them 3-4 times will pay them off easily. And they should last much longer than that, just don't forget they're rechargeable and throw them away! They recharge just perfectly in my regular AA chargers.

I think you’d have a hard time finding a rechargeable AAA battery with only 400 mAh. Most are 800 mAh or more. In other words, these will not last long in heavy use devices. These might be good in a cordless phone, where the phone is constantly put back on the charger. You will not want them in LED led lights. Maybe a remote control or small calculator.These are very good batteries, they just don’t have the power for some stuff.

Batteries arrived quickly, secured well, and in great condition.They look and operate exactly as suggested. I am using them in remote controls presently and will update review if anything unusual happens as I continue to use and charge them.

Batteries are pretty straight forward. These claim to be 400mAh and 1.2 volts. My battery tester tells me it got between 445mAh and 485mAh out of the 4 I received at a draw rate of 400mA. It only gets better the lower you go (even if probably not by much), so unless you're draining the battery in about an hour you're getting between 10 and 20 percent more than the stated capacity out of the battery and I call that excellent.

I kept forgetting to get these batteries every time I went out so I ended up ordering them here. Have no complaints. They work on my really old phone Reasonably priced, charged without difficulty. Working so far. Just as described
