Buying single used alkaline battery for my mp3 player is costly so I decided to purchase rechargeable battery instead. It’s an extra expense but I was thinking of great savings in the long run. Energizer has been my brand because battery power really long lasting. I bought a 2-pack of Energizer AAA battery a year ago and until now, its still working well. Energizer is boasting the feature that their batteries can be charge hundred times and it’s true. The battery performance is still the same from the first time I used it and up to now after numerous charging times has been made. This is because my Energizer rechargeable battery is nickel metal hydride batteries (NiMH) in which according to the experts, loss of battery capacity is not evident in NiMH compared to nickel cadmium (NiCd) rechargeable batteries.
I’m not using Energizer charger but it’s not recommended. To attain maximum battery power, better to use Energizer charger as well. I have my old NiMH charger that’s why I only bought the batteries. A fully recharged battery can last up to 8 hours of continues music on my music player. I have a habit of listening to music to make me sleep. And most of the time, I always forgot to turn off my player that’s why in the morning, and I have no more battery power. Thanks to my Energizer rechargeable battery because now I don’t have to worry much with my battery.
