Where can you buy rechargeable batteries such as Panasonic 1.2 Volt which
are designed to be soldered. I took apart my battery packs for my 18 volt
cordless drill and they have 15 NiCad batteries which say Panasonic 07-99.
They are wrapped in brown paper and made in Japan. Thanks

This is an incredibly common situation, particularly with the el cheapo
Chinese disposable drills - the batteries die long before the drill
wears out. MOST electronic suppliers have them - in Australia, we use a
company called WES. (No use to you, alas) - suggest you contact a local
TV technician and ask to see his supplier catalogues - they have sizing
charts as well. Yours are probably "Sub C" size.

With a decent drill, its worth doing - with a $30 one, no - it will
cost more for decent cells to repack. The ones with welded tags CAN be
soldered - BUT you need to scrupulously clean the tags first (oil from
ther manufacturing process) , use a VERY hot iron (100w) and be FAST to
prevent cell damage. If you have access to a spot welder, thats the
preffered method.
