Counterpoint is where did I last use the battery, very frustrating looking for it when it's needed, plus the more often a battery is used the faster it will fail, having batteries dedicated to a tool is less stressful, having one battery for multiple tools would drive me mad looking for it.
Your mileage obviously varies from mine.
I have a steadily growing collection of Bosch 10.8V (AKA "12V") tools, currently:
- drill/driver
- impact driver
- multi-tool
- jigsaw
The last one is recently new, and a bit thirsty, as is the multi-tool. I only buy something when I need to, so they have all been based on use. The jigsaw is not ideal but it is very convenient.
It is extremely handy to have two or three batteries on the go simultaneously, either to keep one tool running most of the day, or several together (drill and impact driver, for example). Three batteries (1.4AH or 2AH) are enough to cover multi-tool sanding all day. It would be ridiculous to do this for just one tool - uneconomic and I'd have to lug two or more chargers around.
I paint numbers on my batteries, so I can quickly know if one dying, and having them in regular use means I don't get caught out.
In contrast, I have a right-angled drill with a (to me) unique 18V battery and it's a bloomin' nuisance - hardly ever used but vital when needed (e.g. under kitchen units), although at that point the NiCd battery has usually self-discharged. I will probably get a 10.8V one instead.
I don't carry a torch for Bosch, especially as their blue stuff seems to have cheapened over time, but the idea of such a system is excellent, and I've found it very useful.
The exception to this, however, is their quite absurd "L-Boxx" containers - every bit as stupid as the name suggests and a waste of the planet's scarce resources IMHO. Systainers wouldn't have killed them, just hurt their pride...
