Per a previuos posting .....................................
Cordless tools have been around for quite a while now.
So you'd think that some agreement on standard shapes and sizes would have been arrived at?
And before everybody jumps all over that comment; how come we have pretty well agreed standards for light bulbs, fluorescent tubes, plugs/ sockets, water pipe sizes, alkaline and rechargeable cells (AA, AAA, D, C) etc. How come all automobile (almost all anyway) are 12 volts and mostly negative grounded. Telephone dials and/or push button are much the same, world wide. Even debit cards and credit cards are somewhat compatible (often world wide). Tyre sizes and ratings follow standards.. Also within areas of the world radios signals and TV channels are coordinated ............ you don't have to buy a separate TV set for each North American network and your 115 volt shaver will work most places, at least in North and South America from the Canadian Arctic/Alaska to Tierra Del Fuego! Before digital cameras, film came in certain 'standard sizes'; while in the 'early days', my grandfather told me some people used to make their own negative photographic film plates by coating chemicals onto glass plates, in a dark room, (black and white then) no colour of course, until around the 1930s? And then developing their own negatives and pictures.
It's the old 'captive' and short sighted market idea that, among other things, makes American pharmaceutical drugs among the most expensive in the world!
For many quick jobs around the house and especially at the bench the old reliable 115 volt hand drill (BandD $9 at K Mart many, many years ago) is most convenient. It's no heavier and no fiddling around to see which of at least two batteries is charged etc.
But later; batteries age, so it becomes cheaper to get a whole new 'cheapie' drill set with different batteries and a different charger than buy a replacement battery pack/s. It's shame (criminal) how much stuff like that is scrapped!
How does this ISO (Standards) work. Could it be applied to cordless batteries?
