not see much difference with other brands, lightweight batteries from those that could be found there a few years. Small update 7 months later they hardly take over the load, I use it only to feed a baby mobile and also serving me another stack of game bought at the same time Varta brand for the same use I just say that Varta for a few euros more (2 to be exact) still hold both the load for an equivalent number of reloading. I do not recommend this product.
