Although the billions of batteries that are sold worldwide every year usually end up as domestic waste and poison the environment, unfortunately no government has yet made stating the battery capacity on the packaging mandatory. We are strongly in favour of informing customers about the battery usage of electric appliances - and this information should be given on the devices themselves.
- can be stored longer than alkaline batteries (up to 12 years)
- weigh less than alkaline batteries
- are more high-current capable.
The zinc-carbon battery was invented by the German chemist Bunsen in 1841. At that time there were neither generators nor dynamos. In other words, batteries were the sole source of electricity. For more than a century, zinc-carbon batteries served us well, however, we believe that they should no longer be on the shelves. Their energy capacity is usually merely 25 to 40 % of the energy capacity of alkaline batteries. They are not high-current capable, can be destroyed by frost, can only be stored for a limited time and are often not leak proof. Since they can be produced cheaply, they are still on the market where they are sold under misleading names such as “Power Battery” or “Extra Heavy Duty”. We strongly advise against using these batteries.
Alkaline batteries are somewhat more expensive than zinc-carbon batteries, however, they come up favourably measured against the energy reservoir they contain. Their storage capacity is very good, they can be stored for between 5 and 7 years, and also perform well at moderate minus temperatures. They are available at very low prices at discount supermarkets. Always look for the term “alkaline” when purchasing!
