# Question about cordless phone battery

I have a Northwestern Bell 36007 cordless phone. The battery conks out
much sooner than it used to, so I assume it's time to purchase a
replacement battery. The problem is the three stores I have been to so
far apparently don't recognize this model (at least in the compatibility
directories)!

For what it's worth, it uses an NICD 3.6 V rechargeable battery, 450
mAh. As far as type/size/plug, I have found similar batteries in these
stores, but none with the same milliAmperehour value (450).

Does this matter? Isn't this value merely how long the battery will keep
a charge? Is it safe to go with a 3.6 NICD battery that is 1,000 mAh?

TIA.

Sure, it may take a bit longer to reach a full charge, but you'll get
better life than you ever got when the phone was new. The slower charge
will be easier on the battery as well. You can splice on the old plug if
you can't find one that matches too.

Your battery is available directly through Northwestern Bell. Go to:

http://store.unical-estore.com/battery.html Just $5! [And no, using a slightly higher mAh NiCD shouldn't cause problems as long as the voltage is the same, unless the internal charger objects for some reason.] H #### Homer J Simpson Jan 1, 1970 0 For what it's worth, it uses an NICD 3.6 V rechargeable battery, 450 mAh.

On most cordless phones, the internal 'charger' on NiCd powered handsets,
only comprises a series resistor that limits the charge current to a trickle
anyway, and when I used to repair a lot of them before they became full of
uP's all whispering to one another, I regularly used to 'upgrade' the
battery capacity for customers, so I agree with the rest - just go for it.

Also, clean the contacts on base and handset (contact cleaner of
course!)

The only issue you may encounter is with the handsets battery monitor
(if in fact you have one). I've done the same with my Siemens
cordless phone and find it reports that it's always half full. On the
flipside, it can now last approximately a week or 2 without charging,
instead of a day as before.

the more mAh the battery, the longer it will last,
get the bigger battery and be happy!

A caveat with the 1AH battery - will if fit? It's likely be physically
larger than the 450mAh unit.

It is probably just the same battery, but with upgraded marketing.
The mAh claims on battery are somewhat dubious.

With digi-cam AA batteries, I find that the mA labels are pretty true. There
are always web site blogs and camera-buff magazines doing battery-life
comparisons and reporting which brand is giving more flashes than another.
This, I think, helps keep the manufacturers' claims "honest".

Nah, a #2 type pencil eraser does the job, fine.

Plus tax, plus wear-and-tear on your car, plus your time, plus the
cost to repair the parking lot incurred door-ding caused by little
Jimmy getting out of his parent's Lexus.

$11.85 delivered to your door seems like a bargain in comparison.

Not if you're already going to the store or need other items from the
same place, which most people do on a regular basis.

Personally I'd rather get off my ass, get out and have a little human
interaction once in a while than pay more for postage than the item
costs. If a substantial savings of time or money can be realized by
ordering online I will and often do, but for something like a battery
it's easier to just go to the store.

Thanks to all for the feedback. I think I'll go with this one:

You somewhat contradict yourself here. At first you state that you'd
go to the store when you need other items, too. But you end by saying
that just for a battery, it's easier to go to the store. That makes
it sound as if you decided you needed the battery, and jumped in the
car to go get it.

If it's something I need *now*, I'll pay for the gas, pay for the car
wear, pay the 8% sales tax, and get the item *now*. If it's something
I don't need immediately, I'll let UPS deal with the traffic (I live
in Southern California.) My time is more important to me.

As for "human interaction", I can think of countless better ways than
grabbing a battery at Walgreens.

Yah,an eraser will also remove plating (used on many) and won't afford
any corrosion protection.

No, a realist. All except the door-ding is certain. And even the
door-ding has a high probability of occurrence.
