With frequent trips on business trips or travels, a characteristic problem arises - a discharged laptop battery that does not allow to fully work on the road. In this case, spare batteries with you are extremely useful to replace if necessary. Although the problem again arises - how to charge these extra capacity on the road? After all, the option with their constant replacement is also not suitable. With constant replacement of the battery case and compartment for it quickly come into disrepair.
Therefore, the question often arises how to charge a laptop battery directly. There are several effective ways, but they are all done at your own peril and risk - we will only offer information on several available options. But even despite the success of their use in most cases, there is no need to talk about the absolute safety of the method, especially when working with Chinese batteries.
How to charge a laptop battery without a laptop - are the risks justified?
The most rational option - get spare batteries on the road and change them if necessary. But this option with its advantages is extremely inconvenient. Serious loss of time, and the mount itself is not designed for frequent replacement several times a day, soon it simply will not withstand such loads and wear.
You can purchase a spare battery.
In this case, it is worth considering how to check the battery from a laptop without a laptop, which is better for charging it? After all, each battery involves a lot of contacts so that the computer controls the charge correctness.
Previously, special devices for charging spare batteries without a laptop were quite common on the market. But in recent years they have practically disappeared from the market, so the question of how to charge is extremely relevant.
How to charge a laptop battery directly - a proven method
Attempts to charge the battery without the computer itself are rare to be considered, including for the sake of experiments, often ending in serious disruptions and even explosions. This situation prompted all manufacturers to transfer charge controllers from computers to batteries. This approach has become an indispensable rule for manufacturers in the last 5–8 years.
Consequently, for self-charging of the battery of modern models, the supply voltage to the input and output terminals is now only slightly higher than that indicated on it. The best option is for the voltage to match the power supply.
The controller installed here will itself maintain the charge balance of lithium cells, and will interrupt charging at the maximum voltage level.
There will be no particular problems with the search for input and output terminals. Always are extreme battery terminals - the industry standard for household appliances. As a rule, plus and minus are also indicated here. If they are not marked on a specific computer model, use a voltmeter to determine the polarity.
Charger for laptop battery
Another way is to try to find special devices for charging laptop batteries. Recently, they have become rare, but if you wish, you can find a suitable option for your model.
But the most rational option - the presence of several spare batteries, which will be charged in a laptop and take with you on the road. This approach is the most rational and will not worry about the safety of the battery during manipulations with charging.
Do not forget about checking
To check again, use the tester. We connect the tester to the contacts of the power supply, poke them into the battery contacts. If the voltage on the power supply contacts drops to a value close to the battery voltage, then we can talk about the charging process in progress.
Checking laptop battery testers
We looked at efficient and affordable charge principles without the computer itself. But it is important to remember - such measures are available only for reliable batteries of famous manufacturers. Often, Chinese counterparts are not equipped with appropriate protection, so you should not risk it.
We hope that such unpleasant situations with the need for an urgent charge without a laptop will not arise in your life. Although, if necessary, you can use our recommendations - the most reliable and safe approach, proven in practice.
The best option for frequent and long trips and trips is to place bets on models of computers with a long charge, sufficiently capacious battery. And if necessary, purchase and take with you spare batteries - in most cases this is enough to spend 10 hours on the road, staying in touch, solving your household or work tasks if necessary.
