بطاريات باناسونيك إنيلوب برو AA (عبوة من 4)

Put a set in my wireless keyboard and they've lasted nearly three months with heavy daily use, when disposables were dead in a month. Being able to recharge them 500 times is going to save me a lot of money and hassle.

These have been in my camera bag for six months through freezing mornings and hot car rides, and they still hold a charge like they're brand new. The fact that they keep 85% after sitting for a year is no joke, I've pulled them out after forgetting about them and they worked immediately.

Left them in my glovebox through a whole Minnesota winter and they still fired up my flashlight instantly when I finally needed it. The sub-zero performance claim is real, and I’ve recharged them dozens of times without noticing any drop-off.
