What is the difference between NiCad and NiMH batteries?
NiCad batteries use nickel and cadmium, while NiMH batteries use nickel and metal hydride. NiMH batteries have higher energy density and are more environmentally friendly than NiCad batteries.
Is Alkaline better than lithium?
Depends on the usage. In low power drain devices operated mostly at room temperature, alkaline batteries are probably better. In high power drain devices sometimes operated at high or low temperatures, lithium is definitely better. It is best to use what the manufacturer of the device the battery will be used in recommends.
What makes lithium batteries better than other batteries?
Lithium batteries have a higher energy density, meaning they can store more energy in a smaller and lighter package compared to other types of batteries. They also have a longer lifespan and can withstand a higher number of charge cycles before needing to be replaced. Additionally, lithium batteries charge faster and have a lower self-discharge rate, making them more convenient for daily use.
Why is it possible for alkaline batteries to be smaller than zinc-carbon dry cells?
A battery can actually be made into any size, but very small batteries would be drained in a matter of seconds and are thus useless. Since zinc-carbon batteries contain less electrical energy per volume compared to an alkaline battery they are normally used for the larger sizes of batteries. Rayovac has published a graph where the zinc-carbon and alkaline batteries have been compared. It shows that the alkaline battery works just as good after 17 hours of use as the zinc-carbon battery does after only 8 hours of use. (http://www.rayovac.com/technical/pdfs/pg_battery.pdf) Eurobatt claims that alkaline batteries can have 4-15 times longer lifetime than the zinc-carbon type. But it isn't mentioned under what type of conditions this is. (http://www.eurobatt.net/index7201.html?page=213&l=1)
What are examples of primary batteries?
A R6 batterry for a table watch is an example.
What uses mains electricity and batteries?
keyboard can use both
Why are rechargeable batteries better than ordinary batteries?
Because you can use them multiple times.
What kinds of batteries does an itty bitty book light use?
The itty bitty book light can be plugged into the mains or used with a battery pack. The battery pack uses for 'C' batteries. These are larger than the usual AA batteries that most electrical products use.
What does an ac adapter do for a Nintendo DS?
It allows you to use mains power instead of batteries
Why do fire engines engines use electricity from the mains?
Fire engines may be hooked up to the mains when parked, to use electrical heaters to keep the engines at operating temperatures which makes them run better from the start, and to let on-board chargers keep the batteries topped up. Some may even have built-in coolers for medical supplies.
Who has the best car batteries of use walmart or sears?
Walmart sells a good battery at a good price and they are IMO a better buy than the overpriced Sears batteries.
What makes lithium ion batteries better?
Lithium ion batteries are supposed to last longer than nickel batteries. They do not lose charge for up to 10 years in their packaging, and they last longer while in use as well.
Do many countries use different mains voltage than UK?
No.
Do household battery chargers draw electrical power when not charging but remain plugged in?
Everything that is plugged into the mains socket and switched on will use electricity even if it's a battery charger with no batteries in. So yes they do draw electrical power from the mains.
Are kyocera batteries better than other types?
A kyocera battery is a lithium-ion battery. Make sure that the batteries you buy are intended for digital camera use. There are kyocera batteries for many other products including cell phones.
What kind of batteries do you need for my life game console?
you need 3 x AAA batteries. Also it's better to use alkaline batteries not rechargeable batteries.
What is the difference between NiCad and NiMH batteries?
NiCad batteries use nickel and cadmium, while NiMH batteries use nickel and metal hydride. NiMH batteries have higher energy density and are more environmentally friendly than NiCad batteries.
