More AZB's ghetto fixes.

Do some of you folk have old cordless phone with lame dead batteries? Are you tired of buying 16 dollar rechargeable packs for your old Panasonic cordless phones, just to see the new battery lose most of its charging powers in just after a couple of months use? Well I am one of those suckers who have spend lots of money on expensive cordless phone batteries that cost just as much as the new phone and then to find out, I need to change them again just after a few months of use.Just stopped holding charge after some months of use. Now my batteries don't even last 10 minutes of conversation, I hear beeps,reminding me to charge the phone (low battery).
I knew the batteries inside the pack are 1.5 volts Nickel cadmium AA. The problem is, I have new Nickel metal hydride AA batteries. The phone uses a cheap stupid charger which is ok for Nicd but not suitable for nickel metal AA batteries. So I looked on the net to see if someone else had tried it and if the switch works. To my satisfaction, many people have done the switch and are very happy with the results. The old batteries are some cheap Chinese brand 600-700 Mah while mine are 2650 mah. far more current capacity than the factory specs.
here is the link where a solid battery pack is discussed. I did it simpler than that.
Homemade Cordless - Portable Phone Battery Pack

My pack looked something like this:

so I simply just soldered my 3 new doracell rechargeable batteries in series just like the old battery back. Make sure you don't put a blob of solder as the space inside the battery compartment in phone receiver is very compact and to the size. Use your imagination and make it fit. Mine fitted fine and after charging it all night. I talked for 20 minutes and the charge didn't even decrease a bit. I think I will have like 10-15 day standby charge on it and many more hours of talk time as compared to before. To avoid problems, I will not leave the handset on the charger all time. Just to charge it full over night and then leave it out, off the charger. I am happy. The total cost was $9.99 walmart for 4 doracell 2650 MaH AA batteries and I only used 3. These brand name batteries will last a whole lot longer and will give me more talk time as compared to cheap brand 16 dollars batteries I used to buy before.

the above was a defective device and it failed. next???
So if you are not interested, go on to other forums.

Here is a fix for fridges. If you have a fridge which works fine in the frost-free freezer compartment but doesn't get cold in the lower fridge section? Seems like it getting less and less cold below. If you put your hand on the vents while pressing the closed door switch and you feel some air is flowing through it but very little to keep anything really cold. Make sure the temperature dial is set to cold temperature.
Here is what you do. take out meat and other items that need to be refrigerated, put them in a ice box and unplug your fridge and open all doors, freezer and below. This is a good opportunity to clean your fridge as well. Leave the doors open all night and in the morning you will find water leaking from below the fridge. Now clean everything, put back all the items inside the fridge and plug it in and you are good to go. Put your hand on the vents while pressing close-door switch. You will feel stronger cold air flow inside the fridge.
Case closed.

One should make periodic checks to make sure ice has not formed and is blocking the free flow of air to the refrigerartor section if one has that type of refrigerator.

As far as your phone batteries are concerned, have done that years ago.
You can also buy the rechargeable batteries that have "soldering tabs" on then instead of the standard "+" and "-" ends.

PS:
Replacing the batteries in the same manner is also great for rechargable shavers.

Keeping the freezer section and refrigerator section stocked also helps in keeping it cold. Use plastic bottles of water to act as ice in the freezer section, filling up unused space..

Exactly.
The ice buildup forms in the back of the freezer wall on the coil tubing so we never get to see it. This will prevent the air flow from freezer to the fridge below through vents. This is why we disconnect the fridge for a night, open up the doors so all the inside (hidden) ice will melt and free up the air flow in the fridge.

That would be very good if I had a few of them laying around. The regular batteries are not very solder friendly. I had to file them a bit to take the steel shine off them. This way I was able to solder jumper wires and positive and negative wires of the connector.

the pull tab batteries are only 700 maH while the solder batteries are 2100maH. I like the solder batteries better as compared to pull tab ones.
My batteries are even better, 2650maH so they will last much longer.
