When A Battery Dies

We’ve owned a handheld, rechargeable so-called “one-million candlepower” spotlight for going on four/five years now. I bought it at Pep Boys for $9.99. We’ve used it primarily to illuminate the backyard for wild critters prior to letting the dogs out for their nighttime pee.
No surprise: in the past few months the battery’s been on its last legs. Despite a full 12-hour charge, that used to keep the device shining bright for a week or more, the light has started dimming — now to the point where we only get a few seconds of brightness before it fades to black.
My first inclination was to pitch it and go get a new one, but I decided to crack it open and see if the battery was replaceable. Or if not that, at least recycled properly. Sure enough, I unscrew the six screws holding the thing together and find her powerplant to be a 6-volt, 4.5Ah brick of sealed lead-acid deadness. Hopping on the webernets, voila: I’m soon clicking a link to a battery warehouse siteĀ where I find an exact duplicate for $7.95. Nice, but the trouble is shipping the thing’s going to cost me an additional $9.25 bringing the total cost to $17.20 (not including tax). I sigh and look at another battery website and their version is $12.95. I don’t bother checking the shipping. Instead I go over to Amazon and locate a new “one-million candlepower” light for $38.99. I’m pretty sure I could walk into any auto part/hardware store and find a high-powered spotlight for less than that, but then again… maybe $17.20 isn’t such a bad deal after all.
For my last trick, I load the battery up in my pack and bike it across town, on my way to work stopping in BatteriesPlus, a dedicated battery store on Sepulveda Boulevard in Culver City. The clerk tells me they normally stock that type, but they’re presently sold out and won’t get a new shipment in until Friday afternoon.
The cost? $19.95. I’m not sure if I’ll go back there, order it online or just get a totally new one, but at least I was able to leave the dead battery with the clerk who said he’d see it was properly recycled.
Epilogue: You can chalk this post up as one of life’s more trivial trivialities, but to me this shows me why our trashcans are loaded with items like these — and the batteries,too. It may not be entirely cheaper to throw the old out and go buy an entirely new one, but it’s certainly easier.

Oh well it is too late. On the internet my brother found out that 18 volt rechargeable batteries can re shock a NiCD battery back to life.
I use AAA alkaline batteries and recharge them for about 15 minutes if they have less than 1.3 volts of power on the voltameter. Eventually they begin to leak and need to be taken to the recycling center (Or Home depot accepts batteries now).
