Cordless tools: The new Planned Obsolescence
-
Maybe this is something well known, and I'm just late to the game: If you have a cordless tool, you are likely on a forced replacement scheme, and you don't know it. About 10 years ago I bought a cordless hedge trimmer, and its worked well. In the winter I bring it inside and store it, battery out, in the basement where it keeps relatively nice and warm. This year, after recharging the battery overnight, I went out yesterday to trim the hedge. The battery (NiCad) ran down after about 5 minutes, so I'm guessing its just not holding a charge any longer. No problem, I'll just go to the vendor, a national chain, and get a new battery, right? Um, no. That particular battery is no longer available. And so far, I've been unable to locate a third party replacement part. It looks like the battery pack is screwed together, so maybe I can take it apart, and replace the individual cells. Maybe. Its probably soldered together, and I'm not sure I'd trust my soldering skills if I have to solder directly to the replacement cells, if I can even find something suitable. So, in all likelihood, I'm going to have to bin an otherwise perfectly good hedge trimmer, just because I can't replace the battery pack. That's just wasteful. Not to mention an added cost. I do have an old pair of hedge trimming shears, and I used them to finish the job. Maybe I'll just stick with them. But if I replace the electric trimmer, I'll definitely consider a corded trimmer rather than cordless. So if you have cordless tools that are a few years old, it might be worth buying a spare battery pack, or two, for the future.

The problem with battery standards is that battery technology is always improving. Today's best in class is tomorrow's noncompetitive entry, and the pro users who drive the market are not going to go for a weak, short-lived battery. Someday, the improvement curve will flatten and standards will be possible.
That may be, but does the battery format need to be different between vendors, and across technogies? A 20v battery shouldn't matter if is LiIon, NiCad or MrFusion. As long as it can supply 20v at the needed amps, the physical format shouldn't be an issue. Think of all the possible "D" cell battery options. They all supply 1.5v, and can be interchanged one for the other. New technologies don't always require new physical formats.

Yes, but "D" cells are used for everything whereas a DeWalt battery is used only for DeWalt tools. Until there is an outside force to drive the need for interchangeability, no manufacturer has a reason to look at anyone else's format. Standards groups will not get involved because they have no need to drive a commonality. In auto manufacturing, the lithium cells used for cars are standardized due to the financial need for lowering the cost. Even the lead batteries used for powering gas-powered cars have no standards as the size of the draw dictates what capacity battery will be needed. At least they have standardized on 12v as a common voltage. But in tools, not enough consumers even care for anyone to take notice. "The squeaky wheel gets the grease".

I used to use rechargeable nicad batteries with bicycle lights. I learned from the seller that you have to fully discharge the battery before recharging it, otherwise it develops a type of memory where it will not hold more power than you usually use.

An 18v Ni-Cd battery is not going to last very long. All the cells are in series, and so they all discharge and charge at the same rate. But since they don't have exactly the same capacity, the weakest cell will end up being fully discharged first (and possibly reverse charged, which is especially bad for Ni-Cd cells), and it will be fully charged before the others, further stressing it. Once this cell goes bad the whole thing is toast. So fully cycling an 18v Ni-Cd battery can cause it to go bad sooner than mostly discharging it. I have several of the Ryobi one+ series of tools and batteries. All the Ni-Cd batteries have long ago gone dead and been discarded, and all the Lithium-Ion batteries I bought are still going strong. Yes they cost a lot more, but they are well worth the difference in price.

33 for a drill ? That maybe explains it.
And it was a Black and Decker. The DIY stores are always promoting stuff. It is like a battle between them

The downside was that while the drill was £41, the battery was £35. And a brand new model of the drill was just £33.
This is why I buy around November/December when I can get a drill motor, two batteries, charger, and case for $100. A lone battery is around $55.

I thought we learned that back in the '70s. Rechargeable batteries still have not improved sufficiently for occasional use by the average person. Professionals who use them constantly do get their money's worth.
This. My neighbor's a carpenter, and he's been all-in on battery-powered tools for years. What's especially convenient is that since he only buys tools from the same brand, his batteries are all interchangeable. What amazes me is that his batteries will run power tools all day. Why can't I ever get more than 3 hours from a lousy laptop? Both use lithium-ion batteries. To the laptop manufacturers: Make them bigger/heavier, I don't care.
