Which of the following is an important consideration for a battery?
Physical Requirements: Size, shape, weight limitations. Shelf Life: Allowable storage time. Charge-Discharge Cycle: Discharge profile and charging efficiency. Environmental Conditions: Atmospheric conditions including pressure and humidity, shock, vibration, spin, acceleration environment compatibility.
How many hours can a 100Ah battery last?
A 100ah battery can provide 1 Amp for 100 hours, 2 Amp for 50 hours, and 3 Amp for 33 hours. A simple example, but heavy user of power, is a hair dryer that is 10 Amps. A 100 ah battery will give you 10 hours of use.
What is the difference between compatible battery and original battery?
Original batteries are manufactured by companies like IBM and Sony and also by an Original Equipment Manufacturer (OEM), who manufacture under license from companies like IBM and Sony. Compatible batteries are solely made by 3rd party manufacturers.
Why do fuel cells not go dead?
Why do batteries go dead, but fuel cells do not? Batteries are self-contained and have a limited supply of reagents to expend before going dead. Because a fuel cell is constantly resupplied with reactants and products are expelled, it can continue to function as long as reagents are supplied.
What kind of battery do I need for a project?
If you are planning to be somewhat ‘abusive’ to the battery (heavy-usage, running it down all the way) you may want to look at “marine deep cycle” batteries. Is your project super-small, like an inch on each side?
What should you consider when choosing a battery?
For example, if you want your battery to deliver lots of power for your application, the cell internal resistance should be minimized which is only possible by increasing the electrode surface area. This also increases inactive components such as current collectors and conductive aid, so energy density is traded off to gain power.
What kind of batteries do I need for a microcontroller?
7.2V: six AA or AAA rechargeable NiMh batteries is perfect for 7.2V DC gear motors. These are usually in a battery pack rather than as individual cells and you will need a more specific NiMh battery pack charger. 7.4V: two LiPo cells can often power a microcontroller and works great for 7.2V DC gear motors.
What kind of battery do I need for my laptop?
If you are going to have heavy usage of the battery you should go for ‘Marine deep cycle’ batteries. If your electronics need to be super small like an inch on each side you should go for the lithium coin cells or little lithium polymer cells.
