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.
All batteries have an internal resistance and will discharge itself over a period of time.
Use a battery maintainer.
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
First thing is the battery itself. It it has a dead cell it will self-discharge overnight. So have the battery tested to make sure it is good. Secondly is that there is something on pulling power from the battery. Dome, under hood, glove box, trunk, or curtorsey light. You can also have a relay that is sticking.
6-12 hours. The older your battery, the quicker it will discharge.
Almost anything. On newer model vehicles, the engine's computer drains the battery constantly, as does the stereo. Short circuits can cause a drain. Any electrical system that is left on will drain the battery. Even a disconnected battery will lose charge over time and the older the battery, the faster it drains. Also a battery with a dead cell will discharge itself, usually overnight.
The bankruptcy itself will show up on reports very soon after it is FILED. The discharge itself is not reported, just the public record of the bankruptcy itself.
Automotive battery is used for cranking purpose of a vehicle,it needs high current discharge at the time of ignition.Where as an Inverter battery used as a power bank and its discharge is need based at the time of power failure.
