Many people buy a phone for a rather short period of time - a maximum of 0.5-1 year, and then prefer to switch to some kind of novelty. But most still consider the purchase of a smartphone as something more serious and plan to use it for at least 3, 4 years. In such a situation, you will inevitably have to face a situation when the device’s native battery will hold the charge so badly that it will need a replacement.
Lenovo is a popular brand of phones. They have a low cost, high functionality, reliability and unpretentiousness to the conditions of use. The demand for batteries for the models of this brand is consistently high, so the market is literally filled with a variety of products of this kind.
Not all batteries on the market are of high quality and can adequately replace a worn original. There are a huge number of low-quality fakes that are not able to work even half of the declared characteristics.
It is also important to note that there are several main types of batteries on Lenovo, each of which uses different technologies, which has both advantages and weaknesses.

Types of Lenovo batteries
You can classify batteries according to a variety of criteria. Most often you can meet the following categories:
- Original and analogues. Everything is simple here - in the first case, the product is made under the control of the manufacturer. In this case, the batteries comply with all established standards and norms. In such a battery, the capacity will be as declared by the manufacturer. A guarantee will be provided, and the product itself, before entering the market, will undergo a thorough check for operability and absence of marriage. An analogue is a product that was created by third-party companies that are completely unrelated to the Lenovo brand itself, but that make batteries for the corporation’s devices. Here the situation is twofold: some analogues may be normal, and some absolutely not high quality;
- Technology used. This will be discussed in more detail below. Can be used nickel cadmium, nickel metal hydride, lithium ion and lithium polymer technology. Each option is interesting in its own way, although some of these items are already outdated and faded into the background;
- You can also classify according to whether you have a new battery or a used one. The cost of this product is not so high as to buy used batteries. This is applicable only when the phone model is quite old and new batteries are simply not available on it and it is very difficult to find them.
A detailed analysis requires the second item on the list of technologies used in batteries and their features.
Technologies and specifications Lenovo batteries
As mentioned above, there are four main technologies for the production of batteries for phones: nickel-cadmium, nickel-metal hydride, lithium-ion and lithium-polymer.
Ni─Cd - nickel-cadmium batteries. They were common in the Lenovo technique many years ago, but now they are not used anywhere. Their main positive characteristics can be called:
- The ability to withstand a wide range of operating temperatures without loss of performance;
- A large number of recharge cycles - more than a thousand (that is, about 3 years of active use);
- Easy operation and reliability;
- During long-term storage, such batteries practically did not lose capacity and could be easily restored;
- Also Ni─Cd has a rather low cost.
The disadvantages that forced this type to leave the leading position are the relatively low capacity, which is completely insufficient for a perfect smartphone. Strong self-discharge. Harmful components in the structure of the product, which also creates problems with disposal. Also a huge problem here is the so-called memory effect.
Ni─MH - nickel metal hydride. Not widely distributed in the market, so it is almost impossible to buy them. Originally planned as a replacement for the previous version with much less toxicity. They have a smaller memory effect, a large working capacity, a safer chemical composition that does not pose a danger to the environment and people. Quite expensive, quickly discharged even without load, have a high cost.
Li-ion is a lithium-ion technology. The most common battery option today, which is used in the majority of Lenovo devices. Easy to operate. The ability to hold a charge without load for a very long time. Of the minuses - the high cost of such batteries, problems when working in conditions of negative ambient temperature, a fairly short life.
Li-Pol - lithium polymer. These batteries appeared on the market quite recently, so they are not widely used. The main plus is the ability to fill all the space provided, that is, the battery is not in a rigid case, but as in a kind of package.
How to choose a new Lenovo battery
To buy an excellent battery in your Lenovo mobile device, you should pay attention to the following when choosing:
- Product Compatibility. Best of all, if the type of purchased product will be the same as in the original;
- Physical dimensions Even small deviations in the set size can interfere with the normal use of the product on the phone. It is important that it clearly fits the unit. It was inserted without much effort, or vice versa, did not fall out of the nest by itself;
- Capacity. If you want the phone to work as long as possible without additional recharging - choose more capacious products. This parameter is indicated by the letters mAh - milliamp hours;
- Voltage. It is important to see that the rated voltage matches the required in this model of smartphone. Most often it is 3.7 V.
Attention! If your phone has a battery made using a certain technology, then you cannot install a battery made using a different technology. That is, Li-Pol or Ni-Cd cannot be replaced with a li-ion battery.
How to replace the battery on Lenovo
Replacing the battery in the device from Lenovo is a fairly simple task that everyone should easily cope with. True, this applies to smartphones with removable batteries.
On phones with removable batteries
Everything is extremely simple here. It is necessary to turn off the device by pressing the special button or the power key, open the back cover, under which the desired object is hidden and remove the old battery. Next, a new battery is inserted, the lid closes and the device starts. That's all done, it remains only to put the phone on charge and charge the new thing well.
On phones with non-removable batteries
In this case, everything is much more complicated. To change a non-removable battery yourself, you need to have the tool necessary for disassembling the device and some experience with it. If you doubt your capabilities, it is better to take the smartphone to the workshop or give it to an experienced friend.
If you decide that you can get a replacement with your own efforts, then you need to do the following:
- View online (at youtube.com) a training video about your phone model, how to parse it correctly to get to the battery and in what sequence;
- Perform all these actions with your gadget, change the battery and collect everything back;
- Start the device and check its performance.
That's all you need to know to successfully replace the battery in your Lenovo.
