Laptop battery: is voltage really important to respect?

My stock battery was a six-cell 4000 mA·h 11.1 V and the new battery is an eight-cell 4800 mA·h 14.8 V. I know that 8-cell and 4800 mA·h is okay, but what about the 14.8 V instead of 11.1 V? The battery description says it''s compatible with my laptop model (AS5100, model BL51), but the voltage difference makes me wonder.

[SOLVED] Electrical

Is this ~1V differential normal ? I would have thought that since I took the alternator voltage at the thick cable, it would have been past the voltage regulator and thus should be what the battery receives (more or less). Many thanks in advance for any correction and explanation you can provide, MH.

How Much Voltage Should A Car Battery Drop Overnight?

A normal drop is between 0.1V to 0.2V. If the voltage falls below 12.4V, A fully charged car battery should maintain a voltage of 12.6V to 12.8V overnight. A normal drop is between 0.1V to 0.2V. This reduction causes a decrease in voltage. A typical car battery at 32°F (0°C) may lose about 20% of its voltage. At lower temperatures, like 0

Acceptable voltage difference : r/m365

This will get the voltage pretty close to each other. If you don''t want to charge them up, make sure that your batteries'' voltage difference is less than 1 volt. For instance, if your first battery is charged to 39 volts, you would want your second battery to have a voltage of more than 38.5V or lower than 39.5V. Those are the safe values.

6 FAQs about [Battery voltage difference 0 1v]

Is a 1.2V battery better than a 1.5V battery?

While it is true that a 1.2v battery has a lesser voltage than a 1.5v battery, it is not a downside. As most devices that require a 1.5v voltage supply, are designed in a manner to operate at lower voltages than that. Since a 1.2v battery can hold a steady voltage, they are more than qualified to be used in such a device.

What does 0V mean in relation to a battery?

When measuring the voltage between the two poles of a battery, you will read a value. However, if you try to read the voltage between, for instance, an object (like a chair) and the positive tab on the battery, you will likely read "0V". This means that the two points are at the same electrical potential.

What is a 1.2 volt battery?

A 1.2 Volt battery is a rechargeable battery, mostly Ni-MH battery, that maintains a nominal voltage of around 1.2 volts.

What is the voltage of a 1.5V battery?

Actually, a standard 1.5V battery outputs 1.7V when it's new. The voltage gradually decreases as it ages and at around 1.2V it's completely dead. However, it still has 1.2V when not being used. But as soon as you try to draw power from it, the voltage drops to 0V because the chemical reactions can't keep up with the current.

What is a battery voltage?

Voltage is a fundamental electrical measure that indicates the electric potential difference between two battery points. It determines the amount of electrical force the battery can deliver to a circuit. The higher the voltage, the more power the battery can provide to a device.

How many volts should a battery charge?

Two cells charge to 4.2V and one only cell charges to 4.15 or so. If after use, one cell is regularly 2.8 and the other 3.6, then the battery is damaged and needs to be replaced. Cells should never be discharged below 3.0v, preferably not even close to 3.0v
