Battery Economics 101

I bought a package of eight (8) Energizer Ultimate Lithium AA batteries for $13.28 at Loew’s (hardware store) recently. Assuming that’s a typical price point — and it may not be since retail stores are well known for inflating the price of “impulse buy” items placed near the checkout stands — I wondered which type of battery is the better value, primary cells (like the Energizers) or secondary cells (i.e., rechargeable batteries)?

B&H Photo sells an 8-Pack of Panasonic eneloop pro AA Rechargeable NiMH Batteries (1.2V, 2550mAh) for $32.99.

At face value, rechargeable batteries cost ~2.5x more than primary cells. But the secondary cells are rechargeable up to 500 times! In other words, the consumer will recover the extra cost of secondary cells after recharging them only a few times.

External flash units can be real Energy Hogs, especially when shooting at higher flash ratios. So a word to the wise consumer, get a set of rechargeable batteries — they’re worth the extra cost.

Post Addendum

My good friend Mike Powell suggested this blog post should be updated to mention that rechargeable batteries require a charger. I recommend the following combo deal available from B&H Photo: Panasonic Eneloop Pro Rechargeable AA Ni-MH Batteries with Charger (2550mAh, Pack of Four) that sells for $26.30. Done!
