How does a battery loose its charge?

[mr_coffee]

Hello everyone. I'm wondering about rechargable batteries such as in your cell phone. I can't seem to find anywhere on google that explains why they loose their charge if you say... only plug it in for 30 minutes then use it, the next time you charge it, how does that affect how much charge it can now hold/battery life? I know its not a myth but why does that happen?

Different batteriees behave differently. Some batteries must be drained all the way before recharging. If you dont, it will hold less of a charge next time. The lithium batteries in ipods and cell phones don't have these problems. They do, however, have a definite shelf life and will eventually hold less charge and then die

Thank you turdferguson.

My parents yelled at me for not keeping the charge on the battery and said I would kill it. I told them no, it doesn't affect this type of battery. The Lithium ion batteries don't have memory affect which I found out is true.

when u charge a battery, it gets number of electrons (charged particles) from the mains current, later when u play music etc on your phone, your phone system makes use of these electrons one by one and hence they decrease (assume each of the electron gets disappeared as you play music for 30 secs, as it serves as a power)

when your battery becomes very old say 1 year then its capable of handling only certain number of electrons then before so u need to keep charging even more

Hi there,

This is a great question! The process of a battery losing its charge is due to a phenomenon called self-discharge. This occurs when the battery is not being used and slowly drains over time. Additionally, every time you use the battery, it undergoes a chemical reaction that produces electricity. This reaction is not 100% efficient, so some energy is lost in the form of heat. This loss of energy reduces the overall capacity of the battery and can cause it to hold less charge over time.

Furthermore, the length of time a battery can hold its charge also depends on the type of battery and how it is being used. For example, lithium-ion batteries, which are commonly used in cell phones, are affected by the number of charge and discharge cycles they undergo. The more cycles they go through, the more their capacity decreases.

In terms of your specific scenario of only charging for 30 minutes, this can also affect the battery's overall capacity. When you charge a battery, it goes through a process called a charge-discharge cycle. If you only charge for a short period of time, the battery may not be able to fully charge, leading to a decrease in its overall capacity.

I hope this helps answer your question. Keep in mind that batteries are complex systems and many factors can affect their performance and lifespan. It's important to follow proper charging and usage guidelines to ensure the best performance from your rechargeable batteries.

Best,
