Battery Adaptor for cordless tool version 2

Last year I posted my first instructable  for a Battery Adaptor for my old 14.4 Volt  Ryobi  cordless tool set  including flashlight, small circular saw and a drill.
First the charger went, then the batteries died, and then before I could buy replacements the company then switched to the 18V format and dropped all product support for the 14.4V line.
I purchased a new 18 Volt drill from another manufacturer in protest but it really wasn't  as good as my old one, the chuck slips when drilling and the drill clutch does not seem to handle torque well.
So this is my second Battery Adaptor  Hack to resuscitate my old tools cheaply and keep them running!
My newer 18Volt orange and white brand drill and chopsaw combo had a different battery setup than my other 18V batteries that I built my first adaptor too,  Cleaning out the garage and workbench this spring I found my other old dead 14,4 Volt battery and started hacking away....

Step 1 Deconstruct your battery

Take your old battery apart, save the screws, and carefully separate the metal clips off from the battery, You can dry fit the terminal end back inside to the top to see how it fits and what terminal is postive and negative.

To remember wire colours for positive and negative, I usually do "Lighter colour is positive, darker colour is negative". It helps me a lot. :)

Great site for replacing the cells with same or higher quality
Just look for tabbed cells and for better(longer) performance get higher mAh rating.
Hope that helps for future fixes.

why dont you just get some replacement batteries, sub c is generally the size used. They are easy to find online and then you can replace them the same as the ones you had before, i havnt bought a new batt pack in a couple of years.

Good suggestion and entirely possible. Do you know any instructables that show how to solder them together?  In my case the 14.4 V charger broke and I have all these other 18 V batteries around that do better if used a lot than if just left sitting and only used occasionally. Now I have 4 batteries that fit my set rather than the two original.
