Re: Cordless batteries
It started somewhere around 7.2V. Then we saw 9.6V batteries advertised. From there we saw 12V, 14.4V, 18V, 20V,now 24V... how long until we are envying the manliness of 120V cordless tool batteries? That will be really cool... until you drop the battery into your nailbags and short out the contacts. Exploding nailbag anyone?
My point is that while higher voltage is touted as more powerful, that's not necessarily the case. Just like in 12V (OK, it's really 14.4V) automotive batteries, the ability of the battery to maintain a particular voltage at varying loads is going to make more difference than simply the voltage of the battery. Of course, manufacturers don't tell you THAT figure. On the other hand, a higher-voltage battery is usually able to pack more ampere-hours of energy into a smaller package, and deliver that energy at a higher current.
OK, I'll get off my environmentally-friendly, high-efficiency, phosphate-free detergent box now.
