I realized the Christmas that the cost of replacement AA and AAA batteries was excessive, so I thought I'd give rechargeables a try. I had a recommendation for the Tenergy Centura since they retain their charge better than others, So I gave them a try. The package (batteries and charger) arrived quickly and well packaged. The charger has a nice solid feel to it. I have now charged all 16 of the batteries, and am ready to give them a try. I might add that the website proved to be easy to navigate, so getting them ordered was no problem. Considering what I ordered and how well they were packaged, I think the shipping charge was quite reasonable.
