How to extend the life of polymer lithium battery? It is a question that everyone wants to know. Professional lithium battery manufacturer Nuranu shares:

1. When charging the polymer lithium battery, it is best to choose the original special charger, otherwise it will affect or damage the polymer lithium battery.

2. It is best to charge the polymer lithium battery in a slow charging method, and try to avoid fast charging. Repeated charging and discharging will also affect the life of the polymer lithium battery.

3. If the mobile phone is not used for more than 7 days, the polymer lithium battery should be fully charged before use. The polymer lithium battery has self-discharge phenomenon.

4. The charging time of the polymer lithium battery is not as long as possible. For ordinary chargers, when the polymer lithium battery is fully charged, it should stop charging immediately, otherwise the polymer lithium battery will affect the battery performance due to heat or overheating.

5. After the polymer lithium battery is charged, try to avoid placing it on the charger for more than 10 hours. If it is not used for a long time, the mobile phone and the polymer lithium battery should be separated.

Precautions：

The polymer lithium battery does not need to be charged for the first 3 times. It only needs to be fully charged. It will take about half an hour after being fully charged at most. Overshoot and overdischarge will have a serious impact on the life of the polymer lithium battery. Usually should pay attention to charging. It is best to use the original charger, and it is not recommended to use a universal charger.

Talking about charging Li-Polymer batteries, we decided to list our 5 tips for charging Li-Polymer batteries. Now because almost all drones use lithium polymer batteries (LiPo), only lithium polymer batteries are discussed in this article.

1. First make sure you are using the correct charger.

Charge any polymer lithium battery at 1C, almost all drone lithium batteries can be charged at 1C and should be charged at that rate. 1C charging does take a bit of time, but this charging speed is the easiest for your lithium battery charger and won’t cause overheating. This charging rate will give your battery the longest life possible, letting the balance port do its job. For example, a 3400mAh battery charging at 1C sets the charger to a 3.4 amp charge rate.
Both the battery and the battery pack are charged in a fireproof bag during charging, and I don’t see any reason why the battery should not be charged in a fireproof bag. If your charger comes with a temperature probe, be sure to put it in the bag. If everything is packed in a fireproof bag, you can easily and complete the charging.

2. Don’t let your battery go below the minimum voltage.

It’s a flight issue, not a charging issue, but it needs to be addressed. When flying, try not to let the battery drain until the speed control starts to turn off, unless you replace it. Then you have more time, more power until you land the drone. This avoids drone fried chicken, and you can control the minimum speed cutoff, set above the minimum voltage of the battery pack to allow some extra time to set the landing. I like to time my first flight until the speed control cuts off and then set my timer for a minute before the launcher and on all voyages after that I find that the launcher timer is off as soon as I land mine drone.

3. An accident will happen unless the manufacturer’s battery allows it.

Charge the battery above 1C, if the battery is using a higher charge rate, this can save a lot of time when needed. Try not to charge these batteries with a higher rating if you don’t need to. But other than that, I always use the slower rate at home because it increases battery life.

4. Please don’t leave the room when your battery is on the charger.

This is a mistake almost everyone makes, and the number one safety issue when charging. This prevents any minor accident from becoming a major event if not leaving the room. When you are not in the room, while charging, a fire can happen at any time. While charging, you need to be there to monitor your battery. If you must leave the room, stop the charger and disconnect the battery from the charging cable. Then when you go back to the room to charge again.

5. What if your battery has not been used for more than a week, then please charge your batteries, this will keep them balanced and stable.

Storing charge prevents individual cells from becoming unstable and out of balance. I almost always charge my battery and then fully charge it the night before.
