So far, so good. Pop them in and they work, can't attest to the longevity yet, but who cares at this price.

thanks.it is very good deal for the price.i will order again...i already used 8 of them with my daughters toys.untill know i don't have any problem.works fine....

this purchase was misleading - it appears the batteries are energizer brand from the picture, but in reality they are "tian qiu" or something, accompanied by an energizer booklet.
I will have to see how well these batteries last to know if it was a worthwhile purchase.

These seem to work just like other batteries, but of course they may not last as long. But even if they didn't last, at a fraction of the cost of Energizer, this is a great deal. Just know that the Energizer label shown in the picture is for the Energizer watch/electronic battery cross reference guide (the batteries are an off brand: Tian Qiu). As I don't use too many other size batteries, I don't see the usefulness of the battery guide. Probably best used by a watch repair shop.

These batteries are great. Works wonderfully for what I wanted them for. Great value. If I need them again, I will buy this value pack.
