How Do You Know if a Lipo Battery Is Bad

How to Tell If a LiPo Battery Is Bad?

APR xvi, 2020   Pageview：6608

Lithium Polymer (LiPo) batteries are used in well-nigh consumer electronics such as radio due to their loftier ability and long run times. They accept lightweight, available in whatsoever shape and size, have higher capacities and discharge rates.

On the other hand, LiPo batteries require special care during storage and charging for they react to chemicals and can cause burn down hands if they get mechanical damages.

The LiPo battery has a discharge wheel of 400-500 cycles.

How Do You Know If Lipo Bombardment Is Damaged?

LiPo battery or cells are damaged when they bear witness whatever unusual features. They include;

• Damaged plastic cell envelope or visible deformities on the packet of the cell.

• The smell of leaking electrolyte. A physically compromised LiPo bombardment may accept a leaking electrolyte solution. The liquid is acidic in nature, and it may destroy your electronics, while the leaking gases tin ignite because they are combustible.
  

• Unusually high internal resistance (IR). There are several factors that affect IR; they include the quality of the cells, capacity, chemic backdrop, temperature, age, voltage, and discharge rating. Therefore, the IR of a larger battery is low, but when you measure out it and find out that it is abnormally high, and so the cell is damaged.
  

• Dented corners.
  

• Puffing or swelling shows that the battery is damaged, and therefore you should discontinue discharging or charging immediately. Farther, swollen cells have a college IR; thus, you should stop using the entire pack immediately.
  

• Damaged LiPo batteries get puffy, and releases smoke when charging. These signs show that they can ignite at any time.

A good for you LiPo battery should not have whatever of the above signs. Therefore, you lot should stop using these cells and dispose of them properly. Don't store these batteries either. They can explode and cause serious injuries or damages to your personal property.

Users should avoid purchasing used batteries since they could be severely damaged.

How Exercise Y'all Know If Lipo Battery Is Puffed?

LiPo puffing is the swelling that y'all detect on the bombardment or cell. Puffing occurs when the electrolyte forms gas through the process of electrolyte decomposition. It happens when the electrolyte breakdowns into lithium and oxygen or lithium oxide. The compound and so settles on the cell cathodes and anodes based on whether you discharged or overcharged them.

Therefore, puffing takes place when a considerable amount of oxygen is released during the chemical breakdown. Electrolyte decomposition may produce other compounds and elements like CO2. The puffing is accelerated by how you discharge the bombardment, the frequency of charging information technology, storage, quality of the packs, age, and the amount of heat they release when in use.

Therefore, a LiPo cell or battery volition begin puffing due to an calumniating use or slowly over the years. These batteries can even start puffing when they are not in apply and are in charged land or fully discharged.

On the other manus, y'all tin can continue using these batteries if the LiPo puffing is small and goes off when the pack cools downward. Nevertheless, you need to keep the swelling in check and discontinue using the battery if the swelling continues.

The post-obit are tips for delaying puffing.

• Ever use the official charger that was bought with the battery considering less expensive chargers have no voltage requirements rating, and this can contribute to over-charging.

• Avert over-charging or discharging a bombardment. Discharge LiPo batteries when fully charged for they outset overheating quickly, and this contributes to electrolytic decomposition. On the other hand, don't completely drain the LiPo batteries.
  

• E'er apply the LiPo batteries polymer laminated case. Notwithstanding, these cases may non foreclose mechanical damages caused by dropping.
  

• Avert LiPo batteries with small-scale punctures because they are easily combustible.
  

• Go on your batteries in a cool identify to delay electrolytic decomposition.
  

How Do Y'all Know If You Need To Buy A New Lipo Bombardment?

You lot should replace former LiPo battery or cell when they begin swelling, which doesn't become away even when the battery is not in employ. Although the battery may last a few more months, the swelling is an indication that yous need a new battery.

Supervene upon old batteries with reduced capacity. Nigh manufacturers recommend that you should supervene upon a bombardment when information technology begins to concur but 80% of its initial capacity. A new bombardment will eliminate risks such as explosion and will give you a ameliorate performance.

Yous should dispose of a swollen battery properly to avoid causing injuries and damages to your belongings. Even so, you need to belch the bombardment completely before disposing of. Claw a puffed battery to an electrical load such as a resistor or a 20W halogen bulb to discharge it. You can also hasten the discharging procedure past hooking upward several bulbs. The battery is fully discharged when no bulb is lighting. Driblet the discharge battery to a battery recycling facility.

The following tips volition improve the lifespan of your LiPo batteries.

• Employ a quality charge on your new battery. Information technology's essential to charge the battery when it's in the LiPo bag.

• Never employ or charge batteries when they are warm because estrus kills them. Therefore, permit the bombardment to absurd off before charging and give it time to cool after charging before using it.
  

• Stop using your battery when it reaches the minimum-cut-off voltage.
  

• Avert storing your battery in a hot place, such as on the trunk of your car in warm months. You lot should also store them at the right storage voltage since swelling begins 4 hours when the battery has more than 80% charge.
  

Concluding Thoughts

LiPo batteries are prone to catching fire, mechanical damage, or puffing prematurely. Information technology takes more effort to care for these batteries because you need to store them when partially charged, in a cool place, and protect them from whatsoever concrete amercement.

You should stop using a LiPo battery when it begins to smashing, for information technology can't hold the required about the charge. Discard these cells using the proper battery disposal practices after fully discharging them.
