Get Lith Ion Battery to Charge Again
In that location is a certain process to exist followed in lodge to recover a Li Ion battery, and specific tools to be used forth the way.
First you lot need to read the battery voltage using a multi-meter. If the voltage is below a minimum charging level than most likely the bombardment is in a "sleep mode" and you will need to jump-commencement it using a special Li-Ion charger with booster since it will not have a charge from a regular Li-Ion charger. This volition be the initial battery revival. Side by side, the battery must go through a few full cycles of charging and discharging. There is scientific proof that freezing batteries when empty and then fully charging them later turns out to be helpful when doing battery reconditioning.
Li-Ion batteries, or also known as Lithium Ion batteries are widely used beyond most of the modern electronic devices including: smartphones, laptops, cameras, personal tech gadgets, ability tools, etc. They are rechargeable, they accept loftier chapters, lower cocky-discharge, and pretty big number of charge cycles which brand them hugely pop.
If you lot take a Li-Ion battery that seems to be dead, it is worth trying to revive it before recycling information technology.
Permit me explicate each of these phases a piffling more.
one. Battery deconstruction
If you are reviving a 18650 Li Ion bombardment or whatever single-prison cell battery you may skip this step. Otherwise, if you want to revive a laptop battery or power tool bombardment for example, then you lot will demand to deconstruct it, because the actual battery cells you are looking for are packed inside the plastic case.
In order to take apart the plastic case y'all will demand a proper spudger tool kit.
Considering the variety of battery cases available on the market I won't be able to explain how to deconstruct them individually. All the same, using common sense and a little patience will help you in the process.
Hither is an case of deconstructed laptop bombardment example containing 6 x 18650 Li-Ion batteries:
2. Read The Bombardment Voltage
The showtime thing you exercise prior to battery reviving, is to read the voltage using a digital multimeter.
You need this information to encounter whether the battery has transitioned into slumber style. Each Li-Ion battery has a protection circuit that acts as a safeguard that turns the bombardment off if the battery became over-discharged. This happens when the battery is not charged over a longer period. For most Li-Ion batteries the protection circuit puts the battery in sleep mode when it discharges downward to whatever value betwixt two.2 and ii.9 V/prison cell, which depends on the manufacturer.
Any battery with a voltage below this "over-discharge" level it is not advisable to be revived because they are either dead so they will non have charge anymore, or even if they take accuse the capacity will too low so the battery will be unusable.
3. Plug the Battery in Charger With Revive Part
Charger with revive part (too know every bit a charger with wake-up or heave feature) is pretty much different than the regular Li-Ion charger. Whilst the regular charger won't charge the bombardment while it is in slumber mode, the battery charger with booster applies a small accuse current that activates the battery protection circuit and if the cell reaches the nominal voltage, and then the charger switches to the normal regime and continues to charge the battery commonly. This is all done automatically by the charger.
Wait until the battery is fully charged.
iv. Charge and Belch the battery
After the battery is fully charged, annotation downwards the chapters and let it start discharging by sitting over the night or in the following days. Notice how fast they lose the charge.
Go once more through the charging/discharging cycle. Mensurate the bombardment capacity.
If it significantly lost the chapters, yous should probably recycle it, otherwise there are good chances you have revived information technology successfully.
5. Freeze the battery
There are some scientific findings that freezing the lithium battery improves safety and battery life.
For that purpose, put the battery in an airtight bag, then put the handbag in a freezer for around 24 hours. Make sure the battery is completely protected from moisture, so it can't become wet.
Take the battery out of the freezer and let it thaw until it reaches the room temperature (usually it takes 7-ix hours).
6. Fully Accuse The Bombardment
After the battery has restored to room temperature and no wet is left behind, you should proceed with a full charge using your regular Li-Ion charger.
Afterwards freezing the batteries, they tend to lose their charge completely and we take to fully charge them once again.
Up until here you lot accept completed all necessary steps to revive Lithium Ion battery. Hopefully, information technology was successful.
Can I Recondition a Battery at Home
You lot can do battery reconditioning at home with following considerations in mind:
- Basic knowledge in the field of electronics and electrical circuits is recommended. More specially, you should know how to apply a multimeter, how to measure the voltage, etc. If you are a DIY person with previous experience, and then you should not accept problems with following this guide.
- A piece of work desk and proper tools: multimeter, advisable Li-Ion chargers, and other tools mentioned throughout this article;
- Safety equipment: spectacles, gloves, etc.
- Education: If you are a beginner and you want to tap into this field, taking a course will be very beneficial. There are various courses available online, however, there is one specialized class about battery reconditioning that is very popular nowadays. Yous can sentry the FREE intro video here.
Needed Tools For Battery Revival
If you are asking yourself which tools you need to successfully revive (well-nigh) whatsoever Li-Ion battery, here is the list:
- Digital multimeter – we need this tool simply to read the battery voltage, and then we got an initial impression of the bombardment status. Fluke 107 AC/DC Current Handheld Digital Multimeter would be a good choice. It is mid-priced, and it volition come in handy for other repairs, likewise.
- Lithium Ion charger with revive role – chargers that have this revive function operate a little differently than the original Li-Ion chargers. They are able to initiate charging even if the bombardment is in the "sleep" mode.
- Safety spectacles – nosotros must be cautious about our ain safety. Working with onetime batteries could be risky.
- Crocodile clips – these clips are used in situations when you don't have a Li-Ion charger with revive function. In that case, a bombardment with similar specs is used equally an external power source to awaken the expressionless battery from the slumber mode.
- Spudger tool kit – this is needed when y'all demand to deconstruct specific types of batteries, such equally laptop bombardment or ability tool bombardment. I would recommend iFixit Pro Tech Toolkit equally a universal repair kit for all sorts of electronic devices including computers, smartphones, tablets, etc.
- Optional: a battery with similar specs as the bombardment being revived or USB cable. These are used when you can't beget a Li-Ion charger with a revive role.
Tips for Extending the Lifetime of Lithium-Ion Batteries
If properly used, batteries can last longer than their boilerplate lifespan, simply the contrary applies equally well – if they are used wrongly then their lifespan volition exist very curt.
A research grouping from the Academy of Michigan after doing a thorough investigation on this subject has sublimated the following full general tips for extending the Li-Ion batteries lifetime:
- Minimize exposure to high temperatures in storage or use;
- Minimize exposure to low temperatures, especially when charging;
- Minimize fourth dimension spent at 100% charge;
- Minimize time spent at 0% charge;
- Avoid using fast charging unless needed;
- Avoid discharging devices more than quickly than is needed;
- Avoid use or storage in high moisture environments;
- Avoid mechanical damage;
- Follow manufacturer's scale instructions;
How To Revive 18650 Lithium Ion bombardment
18650 Lithium Ion battery is a single cell battery that can we revived using another power source such as Li-Ion charger with analyzer function (also know every bit charger with wake-up or boost feature), or alternatively if you tin't afford that sort of charger you can effort using a second 18650 battery, a working one, that will serve as a ability source to the dead one. Remember that the battery is not dead until it is proved to be dead.
For reviving 18650 battery using this culling method y'all will demand the following tools: digital multimeter, crocodile clips, a working 18650 battery prison cell, regular Li-Ion charger and safety glasses.
Here is a corking video that explains the method of reviving 18650 battery using another 18650 bombardment as power source:
How to Revive a Laptop Lithium Ion battery
Reviving a Li-Ion laptop battery follows the aforementioned process as with any Li-Ion battery, as described in steps ane to six. Yet the first thing y'all need to do is to deconstruct the laptop battery. Nearly of the laptop batteries comprise 18650 Li-Ion battery cells packed in plastic cases along with the bombardment controller. You should be careful when opening the battery pack in order to avert impairment of the parts.
How to Bound Start Lithium Ion battery
In full general, at that place are iii ways to jump start a Lithium Ion battery that seems to be dead.
The beginning and the best manner is to use a Li-Ion charger with analyzer, or with revive part. Unlike the regular chargers, this sort of chargers will first utilize small charging voltage then the jail cell will regain the minimum required voltage and so that the bombardment protection excursion will be activated. After reaching this bespeak the charger will keep with the normal charging manner.
The second style is to use a working bombardment that is with the aforementioned or like specs as the battery you lot desire to revive. You will need to apply parallel charging with the same purpose: to utilise a small accuse to the dead battery then it can regain the minimum necessary voltage so the charging could continue using a regular Li-Ion charger. The average time to do parallel charge is thirty seconds. Remember that the point is to increment the voltage of the dead bombardment just plenty so the Li-Ion charger can "recognize" the battery and continue with charging.
Have crocodile clips and impact the ruby-red wire on the positive terminal on both batteries. Touch the black wire on the negative terminals on both batteries. As soon the circuit is closed, the charging begins.
The third style is to use a USB cablevision where the smaller end is cut off. Y'all can exercise this yourself past using a USB cable, or you tin can as well buy this sort of cable in the It stores already pre-made. The idea is to touch the red wire on the positive terminal of the battery and the black wire on the negative terminal. The other end – the male person USB you will plug into your figurer. The voltage that goes through the USB port is 5V then it will exist plenty to ability up the dead battery. Keep the battery connected for about 1 minute and measure the battery voltage using a multimeter.
Attention: in all cases, closely monitor the battery temperature! It is fine if it gets warm, merely if information technology becomes hot then disconnect information technology from the circuit as before long as possible and stop trying anything else. The battery may exist discharged below the disquisitional level and may not be revived. Hot bombardment also ways that battery may exist degraded too much, and in some cases information technology may explode.
What Practice You Do with dead Lithium batteries?
If you lot take tried to revive a expressionless Li-Ion bombardment and you didn't succeed, or you lot noticed some abnormalities (bombardment doesn't get charged or becomes very hot), then you should recycle the bombardment.
What Temperature is Bad for Lithium Ion Batteries
Lithium-Ion batteries operate normally inside a defined temperature range, which ideally is between 15°C and 35°C. Temperatures higher than 35°C will crusade battery degradation, whilst temperatures below fifteen°C will pb to sluggish electro-chemical science which will farther subtract ability capability.
