Why Rechargeable Batteries Are Rarely Cost Effective September 15th, 2009 I was standing in line at a local electronics store the other day when I struck up a conversation with the guy ahead of me who had a basket full of battery chargers and AA rechargeable batteries. It turns out he had decided to replace all of the batteries in his house with the rechargeable kind. Between the batteries and the chargers this guy plunked down over a hundred bucks!
Rechargeables are best for frequently-used, high-current-draw devices (cellphone, for example). Anything with infrequent battery changes (clocks etc), will take practically forever to reach break-even on costs using rechargeables.
It makes more sense to use alkaline batteries for low-draw devices like wall clocks because they lose power at a much slower rate than rechargeable batteries.
I realize many people want to convert to rechargeable batteries for environmental reasons, which is fair enough. But the truth of the matter is this: when cost is the primary discriminator, low current-draw devices simply don’t warrant the extra expense of rechargeable batteries. That’s because the batteries of low current-draw devices are typically changed so infrequently that the payback period for equivalent rechargeable batteries would be too far long to justify the investment!
