Using Rechargeable Battery is Environment Friendly. The 1.5V and 9V are more popular in small devices and flashlights and can create more E-Waste. So rechargeable better is it not?
There is also a 4.5V Battery or Cell. This is not so popular, it is bigger too. It packs more punch or current, i used it to flash mini Magnesium bulbs. Luckily i did not hurt my eyes in this fascination. Many cells form a battery, but in Normal Spoken English, both mean same. A cell is a single unit of cathode-anode-electrolyte.
