How long will tool manufacturers continue to make replacement batteries for their cordless tools?

there is not a common set period for having to supply spares in law in most countries. things change e.g. upgrades etc and market forces drives supply and price.

i have a DE Walt drill. though I can still ( just ) about get spare battery for it.costs are very high and it makes more sense to get a whole new drill.

some parties are in process of taking an old battery pack.stripping it and replacing internals. this is limited though and again will driven by demand . odds are we ought to if keeping toll a long time? simply get new. a sit will come with warranty and likely be better tool.

Buying by name brand is the best way to go. They last longer, but the replacement batteries are more expensive. It's true that the batteries cost about as much as the whole kit did when it was new, but that's the way it is and we all end up with a lot of "paper weight" lying around. If you buy a name brands like DeWalt or Bosh etc. you probably will have replacement batteries for them way into the future.

It has been my experience that by the time two drill motor batteries will outlast the mechanical components of a reasonably good drill. I prefer the power of an electric circular saw but for drills the ease of use of cordless units pretty much makes it worthwhile to replace them a bit more frequently that corded units.

the replacement batteries are as much and more than some cordless tools ======= I suggest that you buy only those batt-op tools that you will use and stick the corded type tools that you know are dependable ==== unless you put your tool batteries on a charging timer [[ as I have found helpful ]] when you go to use them the batt-power will be low ....................

See if you have a Battery Plus Bulbs store near you. They rebuild most battery packs cheaper the Original manufacturer. Having my DeWalt packs done now.

I don't know how long they keep making the same batteries but when the batteries died on my cordless drill a few years ago, when the drill was maybe 12-13 years old, or more, and I couldn't find replacements in my local stores, I found some on ebay and they were dirt cheap. They are still working 8 years later.

It's a different mind set. I have switched to cordless simply for convienence. It's worth it to me to but replacement batteries or even upgrade the kit so I don't have to drag extension cords around.

Forever there was will always be replacements
