    The best 2000Mah battery ever eneloop AA
    200Mah AA Eneloop batteries are the best I have ever purchased. I have used these for years. Had a digital police scanner that would use up batteries fast. Guy on the scanner forum mentioned eneloop. Got some. Worked fantastic. And ten years later those batteries still work great ! I just bought a 12 pack as I need more for many electronics. Get the 2000Mah you won't be sorry.

    5.0 out of 5 stars Eneloops are the best. Period.
    Reviewed in Canada on March 13, 2024
    There are so many uses for rechargeable batteries that it just makes sense to buy some from a reputable brand. For my money, Eneloops are the best. Period! I have tried other AA rechargeable batteries from other companies but nothing compares.

    PROS:
    + The BEST rechargeable AA battery!
    + Stylish (if that matters to you, ha!)
    + Great battery life.
    + They hold their charge after charging even when not being used so you always have some charged batteries ready to go.

    CONS:
    - The charging time is a bit slower, but this is generally a non-issue. Other versions have a fast charger if that is important to you.
    - More expensive than buying regular AA batteries. (But well worth it, you will get so much use out of these in comparison!)

    If you are looking into getting these and reading reviews you should know by now that most people love their Eneloops and that this is a fantastic product!

    Llegó en buenas condiciones, los materiales se ven muy buenos, es muy bueno que el cargador admita pilas AA y AAA, compré estas pilas ya que un amigo me las recomendo.
    Me han durado bastante la carga desde de las pedí además que ya vienen cargadas y no es necesario cargarlas de inicio.
