Battery drains by itself when vehicle is parked (parasitic draw)
That makes it very unlikely the battery is defective, so the self-discharge test is kind of pointless. – Hobbes. Commented Dec 6, 2016 at 8:42. Add a comment | ... Also I found if I just locked the truck by the key the alarm system would still draw too much current. But by locking the system by the truck key switch, the problem fixed it self ...

How Long Does It Take to Charge 3.7 V Battery?
For example, a 3,000 mAh battery can hold three times as much charge as a 1,000 mAh battery. The discharge rate is measured in milliamps (mA), and it tells us how fast the battery will discharge when in use. For example, a 1A discharge rate means that the battery will discharge at 1mA per hour.
Battery Life Calculator: How Long Does A Battery Last
You just input the battery capacity that''s written on your battery (in Ah) and the calculated amp draw (load current), and the calculator will tell you how many hours the battery will …
How Long Does It Take to Discharge a Capacitor?
This value yields the time (in seconds) that it takes a capacitor to discharge to 63% of the voltage that is charging it up. After 5 time constants, the capacitor will discharge to almost 0% of all its voltage. Therefore, the formula to calculate how long it takes a capacitor to discharge to is: Time for a Capacitor to Discharge= 5RC

5. Operation
Even if the battery can be charged with a much higher charging current (see the Technical data for the max. continuous charge current), we recommend a charging current of 0.5C, which will fully recharge a completely empty battery in 2 hours. A charging current of 0.5C for a 100Ah battery corresponds to a charging current of 50A. Charging profile
