  • What buyers say about Energizer AA Lithium Batteries

    I would recommend using lithium cells for appliances and equipment that need longer replacement intervals due to the longer storage and discharge interval.

    Energizer lithium cells (and all lithium-ion batteries in general), have expiration dates considerably longer because they discharge much more slowly compared to previous generations of batteries.

    I have had Energizer Ultimate Lithium AA batteries in the probe for over a year and they are still working great even in the middle of the winter and during the hot summer months.

    lithium-ion batteries are gaining popularity because of their power efficiency, and are now used in a wide range of household uses, from simple flashlights to sophisticated hybrid vehicles.

    I was happy with the way they were packed and arrived on time, and used them in a holiday wreath, they lasted the whole holiday season, and will do business with them again in the future.
