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.
