Batteries are essential for some of us, either for work or daily living. One pack of non-rechargeable branded AA's could easily reach 200 pesos! It's costly and impractical unless really needed and for emergency purposes. There are cheaper kinds like Eveready but personally, I wouldn't advice you to use Eveready batteries. They might be cheaper but they are only good for a short while -- very short life. I even bought the highest end of Eveready and it was still not good enough. For everything else, the more economical way is to use rechargeable batteries.
When I was just starting photography, the recommended rechargeable AA battery to use in my external flash, according to my veteran photographer friends was Eneloop. That's when I first tried out Eneloop. From then on, I only buy Eneloop because they are consistent and reliable. I haven't done any professional testing on them but the results are always satisfactory that I also recommend them to others and personally use it on everything that I own that needs batteries.
