250v On an automotive battery it is 2.2V
Do a compression test Make sure battery is fully charged Remove all spark plugs Lock throttle fully open Check each cylinder Highest should be within 10% of lowest
2.2v when charged.
Each cell of a modern lead-acid car battery should have an average voltage of about 2 volts but - depending on the cell's condition and its state of charge - the exact voltage at any time may be somewhere in a range from about 1.8 volts (when it is almost fully discharged) and up to 2.25 volts when it is fully charged.

There is no usual. Depends on the quality of the battery and if it was ever fully discharged. 3-4 years is normal. Each time the battery is fully discharged, the life of the battery is shortened.
Short Answer: a partially positive hydrogen atom gets attracted to a partially negatively charged atom. _______________________ Take water for example. There is an Oxygen atom (which pulls electrons towards it-- making it partially negative) There are also two hydrogen atoms. The (negatively charged) electron on each H atom is being pulled towards the O atom, making the Hydrogen partially positive. Now, when two water molecules come together, the partially positively charged H's on one water molecule are attracted to the partially negatively charged O's on the other molecule. This attraction between oppositely charged atoms on different molecules creates a 'hydrogen bond'.
ADP is like a partially charged battery because there is still energy contained within the bond between the first and second phosphate groups. However, it lacks the "high energy" bond that exists between the second and third phosphate groups in ATP.
To charge the X-mini speakers, just plug them into any USB port on your computer or laptop. The rechargeable battery takes 2.5 hours to charge. After it is fully charged, each capsule speaker has a playback time of up to 12 hours. A blue LED light shows when each unit is powered on, and a red light shows when the speaker is being charged.

Consult the manufacturer's documentation for how to extend battery life on a given laptop. Things will differ. From what I have seen in the documentation I have read it does nothing either way to remove the battery, unless you swap in a fully charged one. (I have a couple of laptops that I do exactly this, I have 2 batteries for each so I can swap in the fully charged one, then when both are discharged I recharge both. For both machines the manufacturer suggested always deep discharging batteries to extend their life.) Apple seems to recommend keeping both permanent and removable batteries near full charge most of the time, with an occasional deep discharge followed by fully recharging them. The exception to this is if the machine will be unused for several months, the battery should be discharged to about 25% of capacity before putting the machine in storage, then immediately fully recharged after removing the machine from storage before use. But other laptop manufacturers may have entirely different recommendations.
The voltage (Electro Motive Force or EMF) of a battery depends on the type of cell used and the number of cells in series. For example, the lead/acid battery in a car has six cells in series, and each one has a EMF of 2.2 volts when fully charged but not being charged, making 13.2 volts. When being charged, the voltage on each cell is raised by 0.1 volts, making the voltage now 13.8 volts. When loaded, the battery output voltage will droop to some lower voltage due to the load current flowing through it's internal resistance. The amount of droop depends on the amount of load, the internal resistance, and the condition of the battery. Various other battery systems have other cell voltages etc. Almost all cell types have EMFs in the 0.5 to 5 volt ranges.
