chemical reactions take place in battery which reduce the charge.
You need to use a blocking diode wired in series to prevent battery discharge via the solar panel at times of no sunlight, eg nighttime.
It doesn't actually drain the battery, but without a working alternator to recharge the battery it will only discharge as the car is operated.
a deep cycle battery i a battery that you can charge and discharge over and over without harming the cells in the battery unlike a normal battery . deep cycle batteries are normally used in boats
It is a meter with a high wattage resistor connected parallel with the meter that drains power from the battery while it is measuring the voltage it is used to test the condition of the battery if the condition is good there will not be a large voltage drop while testing the battery
Not necessarily. There could be different components at fault when your laptop fails to charge properly - the power supply (power brick), the charging circuitry inside the laptop for the battery, and/or the battery itself (which in itself also has a circuit for diagnosis, telemetry [battery level, battery health], and overcharge protection).
Either something is on and is drawing current from the battery or the battery itself has a dead cell which will drain the battery. If the battery is over 3 yeas old, replace it.
No, an unplugged battery charger will not cause a battery to discharge.
During battery discharge, the species that is oxidized is the anode.
All batteries have an internal resistance and will discharge itself over a period of time.
Use a battery maintainer.
To effectively discharge a NiMH battery using a NiMH battery discharger, follow these steps: Connect the NiMH battery to the discharger according to the manufacturer's instructions. Set the discharger to the desired discharge rate, typically measured in milliamps (mA). Monitor the discharge process to ensure the battery does not overheat or over-discharge. Once the battery reaches the desired voltage or capacity level, disconnect it from the discharger. Properly dispose of the discharged battery according to local regulations.
To safely discharge a NiMH battery, you can use a resistor or a specialized battery discharger. This will help prevent over-discharging, which can damage the battery. Make sure to follow the manufacturer's guidelines for proper discharge procedures to ensure safety and prolong the battery's lifespan.
Either there is a dead cell in the battery or something is drawing power from the battery. Even a good battery will slowly discharge over time. Normally it will take months.
To get the rated capacity, limit the discharge rate to 0.25C
It depends on the type of battery, and the capacity of the battery, and the application you are using the battery for.
recycle it
6-12 hours. The older your battery, the quicker it will discharge.
