Highway robbery...
I've had a 3m Airmate for a number of years now, and my battery is
pretty much at the end of it's useful life. I pulled up the battery in google and the price ranges from around $95 to over $175 or more. Krappin' Krishna! I'm on my 2nd battery and some years ago I tore open my first pack and it consists of three D-cell nicads wired together. Three D-cells. It boggles the mind. Worst part is, there's a metal strap that connects them all that is sort of stapled into the top and bottom. It would be *so* easy to make that pack such that you can pop the lid, and drop in three new batteries. But nope. Not a chance. Chalk it up to corporate greed or lawyers being involved. Or both. Wonder if Batteries Plus could renew my old pack for a reasonable cost? Sorry for the OT rant, but this urks me. Besides, we haven't had any decent COC activity in ages... ....Kevin -- Kevin Miller Juneau, Alaska http://www.alaska.net/~atftb In a recent poll, seven out of ten hard drives preferred Linux. |

For the solder, but keep on time to a minimum to avoid the cell gassing off. Remember to neutralise the flux when finished. Most D cells have no more current capacity than the average AA cell, its just extra padding. So Buy 3 NIMH cells (replacement for NiCd's) You may even get two sets of three in the same space, but watch for heating during discharge. I recently had a similar issue but my device, 18V used 15 NiCd cells , approximately C size. Now sporting 16 tagged NIMH's. They take up less space, are lighter, and have 50% more current capacity. I got my cells from ebay. Saved about 80% on a new battery pack -- John |

I have soldered wires to AA's, C's and D's, and have never had a problem. I
use D cells to power the LED on my guided hollowing tool with excellent results--the batteries last a really long time, even when I occasionally forget to turn off the light. |

You might change batteries only to find your charger won't work with the new ones. Robert |

How do these people sleep nights? Part of the issue is the cost of any mould tool needed for the plastic parts, they have a finite life before going out of tolerance. Secondly its likely they make the packs in large numbers, with a nominal number for failures , and a quantity for spares. There is no guarantee the spares will sell so may end up on a shelf for a long period. Storage = cost, so it gets to a point where the storage cost out-weighs the sale value. So higher price allows for longer storage, and thus availability. Remember, its not the managers, supervisors or even assembly staff making the decisions, they have common sense to see the need. Its usually the accountants making the decisions -- John |

If so, make yourself a battery pack to clip on elsewhere and run from that. 2) If not, can you wire one up without compromising seals? Either way, you could toss the existing charger and use whatever you want as long as it gives ~4.5V. NiMH with different charger, alkalines, AC adapter, hat with a bunch of solar cells, whatever. |
