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.
The way to stop your laptop from charging is to unplug the charger from the computer. When the battery starts to get low on power plug it back in.
yes
this is actually really simple to fix. all you have to do is: 1. plug in your charger 2. take out your battery from your computer for about 20 seconds. 3. put your battery back in.
You can with most laptops, but then the battery will not be charged. Try it - if the screen goes blank when you pull the battery out then it's off. For most laptops, you only get 1 battery pack out of the box and in order to maximize the battery's life time, once u have a fully charged battery u can remove it when u have an AC power on, so that the battery wont keeps on charging. Cant the laptop detects if the battery is full and cut off the charging? Yes, in most of the cases, but it is still a myth if hooking on both AC and battery together will shorten the battery's life time.
a simple battery charger only charges the battery and having no feedback from the battery status, it can cause overcharging, increase temperature, and can damage the battery or in worst case can blow up the battery, also mitigates the life time of the battery. whether intelligent battery charger charges the battery and get feedback from the battery , when the battery gets fully charged it Cut off the charging circuit itself, also maintain the charging at its trickling current to control the temperature. simply it shows the status of the battery. i hope its the Good answer. thanks although the intelligent battery charger charges the battery and get feedback from the battery,the batteries have different charge characteristics. For example ,some intelligent battery charger detect △V and △T to control charge. However when batteries has been charged fully,they will show different characteristics. some battery has show the voltage dropped,but in fact they has not been charged fully,even charged a little just because the wave input voltage.some batteries has show the voltage dropped,but the batteries has charged fully for a long time.So acccording to the △V not to determine the fully charged.△T has the same problem and when the same battery charged fully will come different temperature,if the charging current is different. So △T is worse than the △V. Finally,although the intelligent battery charger can get feedback,now the battery charge characteristic is unsure.So it is no sense. I think battery charge should be distinction by constants current or constants voltage.they will produce obvious different effect of charge.
Yes! You can buy trickle chargers that work through the cigarette lighter.
Not significantly. So long as it is done using a properly designed smart charger, most NiMH batteries can be recharged in about an hour without any damage or significant reduction in their life. However, NiMH batteries must only be rapid charged with a charger specifically designed for charging NiMH batteries. Chargers designed to rapidly charge NiCd batteries can overcharge NiMH batteries. While it may be true that rapid charging NiMH batteries can reduce battery life by a small amount (probably less than 10%), this should be more than offset by the inconvenience of always slow charging batteries.
Charging a re-chargeable battery.
The charging system may be over charging the battery. Over charging the battery can speed up the evaporation process. Have the electrical system tested.
The alternator might not be charging the battery
any short in the electrical system will have an effect on the charging system
To make a rechargeable battery have electrical energy, it needs to go through a charging process where it stores electrical energy. Thermal energy is a byproduct of the charging and discharging processes due to internal resistance and inefficiencies in the battery, so the battery naturally generates some thermal energy when in use.
The process of charging a storage battery.
Yes, lithium batteries can be recharged multiple times. The process involves connecting the battery to a charging device that provides the necessary electrical energy to reverse the chemical reactions that occur during discharge, thereby restoring the battery's energy capacity for future use.
battery no longer can store a electrical charge, a charging system failure, a parasitic draw,
Powertron India Pvt Ltd is one of the best manufacturers and suppliers of Battery chargers in Thane. It is a device that helps in storing energy in a battery by running electric current, battery chargers manufacturers are used for charging large battery banks and also provide DC output to load. They also provide top-class battery chargers for industries at affordable prices for their customers, they manufacturers these batteries with top-quality materials and best-quality components. It is highly reliable and cost-efficient for all power suppliers, they are designing, developing, and manufacturing battery chargers in India(Thane).
Most mobile chargers aren't really chargers, but rather a power source. The electronics that monitors the charging and stops it when the battery is full is all in the cell phone. IF you hook the cell "charger" straight up to a battery you run the risk of disastrous overcharging.
