    The following is an updated version of my original Sanyo eneloop FAQ, first published in may 2012


    The eneloop Pros and standard eneloop2100 use fourth Gen technology, which gives them a wide operating temp range, improved stability in output, slower self-discharge, and increased durability.


    I bought a La Crosse BC-500 to use in a car with solar cells, as it is the only La Crosse that can be used this way, with a 12 v plug included.


    The eneloop Pro battery is a descendant of the long-standing tradition of NiMH batteries that run circles around most of the competition.


    This battery is very good for low drain and high drain applications. It has a cycle life of over two years, which is four times that of the XX or Pro.

    Common Questions

    Q:

    Is there a difference between SANYO's eneloop XX and Panasonic's eneloop pro?

    A:

    The only real change to the batteries is the number of charge cycles, the batteries are rated for up to 500, and the milliamp is 2550 versus 2500.

    Q:

    This seems to be one of the highest capacity AA batteries out there. Are there any other NiMh AA's that have higher capacities?

    A:

    PowerGenix had a NiZn AA battery, but it still wasn't as good as the eneloop Pro / XX line.

    Q:

    How long does it take to fully charge the batteries with the eastshine s2 charger?

    A:

    It depends on the average voltage for the battery within a single discharge and how long it will take.To go from 1.10 volts to 1.28 volts is close to a full charge, but it will take less than an hour.

    Q:

    Is it possible to use my Energizer® Recharge® Value Charger with these batteries?

    A:

    The energizer charger will charge your batteries too high a rate and reduce the life and number of cycles of your batteries.

    Q:

    If Ni-MH batteries are left in something without being used, are they hurt?

    A:

    You can charge them at any time, and there are some smart charger/analyzers out there that can drain your cells for you or better yet check the performance of your cells.
