to complete the circuit to continue the flow of energy wherever the energy is going!
There is a plus and minus side on all batteries to indicate the polarity of the battery - positive (+), negative (-), this way one knows which part to match with the device. Plus on the battery has to match the plus on the device and same for the negative in other for the device to function.
plus is the positive terminal (cathode) minus is the negative terminal (anode)
they do because like magnets we have negative and positive ,negative and negative repel and vise verse but positive and negative attract
They put a +(positive) and -(negative) on each side. The + matches with a - and vice versa.
Because one side is the positive side (+) and one side is the negative side (-) They need to be there so people can place them in correctly. On objects there is also a plus and minus sign to match with the ones on the battery. You place the end with the plus sign in to match the end with the plus sign on the object and the end with the minus sign to match the minus sign on the object. Hope this helps!
The plus side of the battery has a NIPPLE on it. The negative side of the battery is flat. Hope this helps
With regular dry cell batteries, the flat negative (-) side always sits against the spring.
To increase the ampacity of batteries operate them in parallel. Plus to plus, negative to negative. By connecting them in series will increase the voltage and this might no be a good idea for devices that require only the specific voltage of 12 VDC.
" Anode " is generally refer to POSITIVE. Cathode generally refer to NEGATIVE. But these terms are use for different applications ( For example: you wouldn't refer to the POSITIVE side of a battery as ANODE or NEGATIVE side as CATHODE, it commonly refer as positive or negative when you are dealing with battery application etc. )
Battery technology has both negative and positive aspects. On the negative side, batteries can be expensive, have limited lifespan, and can be harmful to the environment if not disposed of properly. On the positive side, batteries provide portable power, are rechargeable, and can store energy from renewable sources like solar and wind power.
Look on the plug. Usually the negative side will have a small minus sign on it. The positive side is the one with the plus on it.
Batteries plus carries all the brands of laptop batteries, the only thing is dell would be cheaper.
