How Long Does A Lipo Battery Last?
Many LiPo batteries aren’t rated to survive more than 300 charge cycles. An entire charge cycle is understood to be a complete battery being drained to empty and billed to total capacity within this context. But, measuring a LiPo battery’s lifespan might not be practical, as batteries undergo varying depths of release when they’re used.
Many producers have said that their LiPo batteries may last two or three decades. This can be a somewhat realistic approximation to get a situation where a battery is frequently used and billed around two or three times every week. But, battery replacement predicated on date postage may not apply to all situations, as it doesn’t consider the degree of use.
Whatever the circumstance, a LiPo battery is considered to begin “aging” the first day it is activated. This is applicable if the battery is below routine use or is saved for a longer extended period. The way the LiPo battery performance deteriorates during storage is decided by its storage requirements, as we will cover in greater detail afterward.
In summary, a sensible approximation of a LiPo battery’s lifespan ought to consider both its number of charge cycles and its era. Whatever the circumstance, a LiPo battery has been regarded as past its useful lifespan when its capability has dropped to approximately 80 percent of its original capability.

What occurs when a LiPo battery is beyond its lifespan?
Luckily, a LiPo battery doesn’t necessarily experience catastrophic failure when it’s past its lifespan. As previously mentioned, a LiPo battery that could only hold 80 percent of its original capacity is considered beyond its prime. That is an irreversible process, so this battery will only continue to deteriorate until it can’t hold a charge.
Comparatively speaking, an older LiPo battery will probably show signs of swelling or puffing since it nears its expiry stage. Swelling of LiPo batteries occurs because of the gas produced by the battery’s electrolytic solution decomposition.
Apart from having significantly diminished performance, a bloated LiPo battery also has a higher probability of catching fire when it overheats. Therefore, you probably won’t wish to wait till a LiPo battery can’t hold a charge. It will become dangerous to keep on using it until it reaches this stage.
What causes a battery to era?
For most of us, batteries hammering over time is only the fact that we’ve begun to take. What causes LiPo batteries or even some other battery, for that matter, to deteriorate anyhow? To understand this phenomenon, we must learn how the different battery elements socialize to produce the battery function.
A battery includes three chief elements: a positive end (cathode), a negative conclusion (anode), and an electrolytic solution. Between the cathode and anode is a polymeric separator that ensures they don’t come into contact and lead to a short circuit.
The electrolytic solution enables ions to move from the cathode to the anode and vice versa. Charging the battery compels ions to move from the cathode to the anode. Employing the battery reverses that this stream.
But this process of ion exchange isn’t perfect. For example, while lithium ions migrate from the anode to the cathode while the battery has been used, many of these lithium ions become lodged into the anode.
This thin film made from lithium, known as a robust electrolyte interface (SEI), develops with battery cycles. An identical restrictive layer, known as electrolyte oxidation, forms on the cathode.
Even though these layers are just made up of nanoparticles, they accumulate over time and affect how the cathode and anode interact with the electrolyte solution. With more cost cycles, the layers on both cathode and anode continue growing, decreasing the number of websites where electrons in the electrolyte solution can bond.
The declining capability to maintain ions in both the cathode and anode clarifies why a battery’s capacity to hold a charge reduces the longer it’s used.
Another process that leads to the corrosion of a LiPo battery would be that the occurrence of electrolytic decomposition. LiPo batteries utilize an electrolytic solution composed of a lithium-ion which is more gel-like in feel compared to the liquid electrolyte solution used in lithium-ion batteries.
Whatever the case, these electrolyte solutions tend to decompose over time, producing gases like oxygen, carbon dioxide, and carbon dioxide. Gas production describes the swelling or puffing that many batteries typically undergo when they get older or poorly handled.

Tips about prolonging the lifespan of your batterys
Though LiPo batteries will deteriorate to a point where they can no more be utilized, there are two or three things that you could do to postpone their expiration. Listed here are a few of the best practices for handling, charging, and storing all LiPo batteries, which may prolong their lifespan.
1. Store in a Cool Location
A LiPo battery proceeds to age and deteriorate, even while it’s stored in storage. On the other hand, the corrosion process becomes hastened while the battery is stored at significant temperatures.
A study revealed the ability of a batterys stored at 60 degrees C for three months has dropped to just about 75 percent of its original capability.
Another battery held for a similar period at 25 degrees C deteriorated but to a much more minor level: it managed to keep 96 percent of its original capability. It’s possible to keep LiPo batteries in near-freezing temperatures, which was demonstrated to preserve its ability better.
2. Shop at roughly 40 percent to 50% battery capacity
A study comparing how electrons kept in different capacities behaved when it comes to corrosion revealed that keeping around 40% capacity just led to roughly 4 percent capacity reduction after one year of storage.
Another battery kept in similar states but has been fully charged deteriorated by up to 20%. In its fully charged condition, the accumulation of electrons at the anode contributes to the quicker accumulation of this restrictive SEI layer.
On the reverse side, keeping a battery that’s entirely drained runs the possibility of the battery’s protective circuit neglecting. It follows that a battery that goes to a”deep discharge” condition may not have the ability to hold a charge in any way.
As a guideline, it’s ideal for keeping LiPo batteries 3.6 V to 3.8 V. This can be applicable for regular LiPo batteries, which maintain 4.2 V per cell when fully charged. Charging a LiPo battery to total capacity should be acceptable if you use or release it within two or three days.
3. Don’t over-charge or over-discharge
Another massive no-no for LiPo batteries is leaving them plugged in even when they’re already fully charged. This can result in “trickle charging,” or the battery recharges process using the tiniest drop in voltage.
Apart from hastening the corrosion of the battery, leaving it plugged also will lead to corrosion. As we’ve said, warmth is a significant weakness of LiPo batteries.
It’s also not a fantastic idea to utilize a LiPo battery before it’s empty. To get a 4.2V LiPo battery, discharging to 3.0 V is deterred. By allowing a battery to enter “deep discharge,” you’re enabling some of the anode material to dissolve in the electrolyte solution.
Usually, batteries have built-in voltage thresholds that stop them from entering deep discharge. But a drained battery that’s saved for quite a very long time will continue to release and will move below the threshold voltage value.
4. Use only official chargers
Should you stumble upon a bargain that provides $5 chargers to your LiPo battery, then odds are you will wind up spending more about replacing those batteries shortly. Cheap chargers might not be rated for your particular battery model, which might cause overcharging or overheating your LiPo battery.
Multi-cell LiPo batteries are particularly prone to becoming unbalanced when utilizing cheap chargers. An unbalanced LiPo battery includes cells that have different voltage values and so provide power at irregular prices.
It follows that individual cells can readily secure over-charged or over-discharged. An unbalanced LiPo battery can be quite harmful and will probably have to be disposed of.
Should you care about maintaining your LiPo batteries secure and operational, then you want to put money into a high-quality functioning charger.

15 Things Every Lipo Battery User Should Know
1. Never charge, release, use, or keep a busted or bloated LiPo battery. Instantly follow proper disposal protocols.
2. Avoid buying used LiPo batteries. You never know precisely what the former owner did together, and they might be severely damaged. “LiPo Battery Like New, Used After” is usually a scam and should be prevented.
3. Always use a proper LiPo battery equilibrium charger/discharger when charging and discharging your LiPos. All cells at a LiPo battery must keep the same voltage across all cells constantly.
When the voltages across the cells deviate a lot from each other (5mV ~ 10Mv), the battery can become dangerous and unstable. (Unless it is just one cell LiPo, in which case you don’t have to be concerned about cell equilibrium ).
4. Always use a flame-proof LiPo safety tote, metal ammo box, or alternative fireproof container whenever you’re charging, discharging, or keeping your LiPo batteries.
Even though LiPo fires are infrequent, they could occur incredibly fast and may do a great deal of harm. All it requires is the internal short circuit to place off the battery.
There’s not any way to forecast when it will take place. It tends to occur more frequently when batteries are fully charged, overcharged, or discharged, but it might happen to almost any LiPo at any moment.
Never fill the container capacity with your batteries. Always follow manufacturer recommendations on LiPo luggage for just how many’s it could safely contain. It is ALWAYS worth investing in an (under $10) explosion-proof LiPo tote or ammo can.
5. Don’t use your flight case/travel situation for long-term LiPo storage. The plastic and foam in these types of instances can help disperse a LiPo fire. Always use a fireproof container like a metal ammo box or fireproof secure for storage.
6. Never leave your LiPo batteries charging while unattended. If a battery begins to become bloated, smoke or gets fire, you have to be in a position to deal with the circumstance immediately. Walking away for just 5 minutes may spell tragedy.
7. A LiPo fire is a chemical flame. Always maintain a Class D fire extinguisher near your battery charging/discharging and storage space. The battery charging/discharging and storage space should be free of any materials that can catch fire, like wood tables, carpeting, or gasoline containers. The perfect surface for charging and keeping LiPo batteries is ceramic.
8. Never overcharge a LiPo battery life. Typically a complete fee is 4.2v for each cell. Never “trickle” charge a LiPo battery life.
9. Never release a LiPo battery under 3.0v each cell. Ideally, you don’t ever wish to go under 3.2v per cell to keep healthy battery life. 2.9drops per cell and reduced are causing irreversible damage.
10. Never leave your LiPo batteries sitting on a complete charge for over 2-3 days. If from the 3rd day you know you aren’t likely to utilize your battery now, you want to release your battery to 3.6v-3.8v a cell for secure storage until you’re all set to utilize the battery.
11. Care to your LiPo charger properly. Always keep your LiPo batteries at room temperature. Don’t save them in a hot garage or a cold fridge.
Although a chilly battery has a significantly less chemical reaction, which may prolong its lifespan, carrying out a battery from a cold refrigerator can lead to condensation occurring on the battery’s life’s interior, which can be pretty dangerous.
12. Always keep in mind that heat is the number one enemy of LiPo batteries. The hotter your batteries have, the shorter their lifespan is. Never charge a battery that’s still warm from use, rather than use a battery that’s still warm from charging.
13. Based on how they’re utilized, many LiPo batteries usually don’t last more than 300 charge cycles. Leaving them about on a complete or depleted charge all of the time, running them entirely lifeless, or exposing them to high temperatures will shorten this lifespan dramatically.
14. LiPo batteries don’t work well in cold weather. The colder it’s, the shorter your run times will probably result from the slowing of this chemical activity inside the battery. When it’s under 14F (-10C), then LiPo use isn’t wise in any way. Your battery can cause your R/C automobile to fail without warning at such temperatures suddenly.
15. Always pack your LiPo batteries into your carry-on tote rather than in your checked luggage when traveling on a plane. It is the law.
