Is there any difference between the ThinkPad T470 dual battery and the single battery

1. The appearance is different: the double battery base is flat, the single battery base is convex, the double battery, one built-in, one external, go out to carry, feel heavy, just unplug the external battery. Dual battery means that the computer has two electric back batteries, one embedded and one external, which can improve the use time when not charging, even if the external battery is unplugged, it can still be used.

2. The battery life is different: the biggest advantage of the external battery is that the part of the external battery can be plugged and unplugged and expanded at will, and there is no need to turn off the power and then replace it (provided that the built-in battery is charged);

The disadvantage is that the charging and discharging logic of the two batteries is sometimes chaotic, and the earliest logic is to give priority to ensuring that the built-in battery has power first.

The single battery cannot be removed at will, and the battery life mode also relies on the power supply of the single battery.

3. The charging logic is different: the second battery in the double battery is the second battery independent of the main battery, and its charging logic is as follows:

When there is a second battery in the optical drive position, it is prioritized for discharge, and when charging with an external power supply, the main battery is preferentially charged, even if the main battery is higher than the secondary battery, the main battery is also preferentially used. Two batteries cannot be used or charged at the same time.

A single battery is a computer that relies on power supply when connected to a power supply, and the battery is charged, and when it is not connected to a power supply, it relies on a single battery to charge.

Distinguish. First, the battery base is different.

1. Double battery: The base of the double battery is flat.

2. Single battery: The base of the single battery is protruding.

Second, the functions are different.

1. Dual battery: Dual battery, one embedded and one external, can improve the use time when not charging, even if the external battery is pulled out, it can still be used.

2. Single battery: only one embedded one, the computer cannot be used standby after unplugging.

Third, the battery life is different.

1. Double battery: The battery has a higher power and can be used for a longer time.

The dual battery base is flat, and the single battery base is convex.

Double battery, one built-in and one external, go out to carry it, and if you feel heavy, you can unplug the external battery.

Dual battery means that the computer has two batteries, one embedded and one external, which can improve the use time when not charging, and can still be used even if the external battery is unplugged.

Summary. Charging does not need to be turned off or turned on, plug in the power supply at any time and charge at any time, battery power supply and power supply are two independent power supply systems, and the two systems can be switched with each other. When you put the battery on, it's battery powered.

The order of priority is: the plug power supply is prioritized (whether you install the battery or not, if you do not install the battery, it is the power supply, at this time, the power is off, and the computer is directly turned on; If the battery is installed, the power supply will charge the battery, and it will also be powered by the power supply after it is fully charged, and the battery is useless, and the computer will automatically switch to battery power supply at this time, and it will not turn on, protecting the computer in use). In general, it is:

Plugging in the power supply is to power the power supply and charging the battery, after the charging is completed, the battery is idle, unplugging the power supply is the battery power. Plug it in at any time and charge it at any time. There is no time limit for charging, it is automatically not charged when it is fully charged, and the battery only works when there is no power supply.

Charging does not need to be turned off or turned on, plug in the power supply at any time and charge at any time, battery power supply and power supply are two independent power supply systems, and the two systems can be switched with each other. When you put the battery on, it's battery powered. The order of precedence is:

The plug power supply is prioritized (whether you install the battery or not, if you do not install the battery, it is the volt power supply, at this time, the power is off, and the computer is directly turned on; If the battery is installed, the power supply will charge the battery, and it will also be powered by the power supply after it is fully charged, and the battery is useless, and the computer will automatically switch to battery power supply at this time, and it will not turn on, protecting the computer in use). In general, plugging in the power supply is to power supply and charging the battery, after the charging is completed, the battery is idle, and unplugging the power supply is battery power.

Plug in at any time, quietly reput, and charge at any time. There is no time limit for charging, it will automatically not be charged when it is fully charged, and the battery only works when there is no power supply. As for the time to watch, different batteries are different, generally you can watch two or three movies, that is, 3-4 hours, and many hours (but this kind of battery is rare).

Battery 2 keeps showing zero percent.

That may be due to the aging of the battery.

It's just that the second piece can't be used.

Yes. How much does it cost to buy another piece.

Can't make it, I don't think the first piece is resistant.

200 yuan. It's okay if you don't use batteries.

No, it doesn't. This will heat up the battery.

Hello, it is a pleasure to serve you and give you the following answer: Different. The Lenovo T470 battery model is 45N1782, and the Lenovo T480 battery model is 45N1781.

Reasons for the problem: 1. Different battery models: Since the battery models of Lenovo T470 and T480 are different, problems may also occur with different batteries.

2. Different battery specifications: Since the battery specifications of Lenovo T470 and T480 are different, the output voltage and current are also different, so using different batteries may also cause problems. Workaround:

1. Check the battery model: Before using the new battery, you should check whether the battery model is the same as the original battery model. 2. Check the battery specifications

Before using a new battery, you should check whether the output voltage and current of the battery are the same as the output voltage and current of the original battery. Steps: 1. Check the battery model

First of all, check whether the model of the new battery is the same as the model of the original battery, if it is different, it can be used without wheel roughness. 2. Check the battery specifications: check whether the output voltage and current of the new battery are the same as the output voltage and current of the original battery, if they are different, they cannot be used.

1. The model of the battery: The model of the battery refers to the brand and model of the battery, which is the only identification of the battery. 2. Specifications of the battery:

The specification of the battery refers to the output voltage and current of the battery, which are the main parameters of the battery.
