How To Store Your Li-Po Battery For A Long Time [battery]
Of all the innovation that paved the way to the rise of electric RC flying, battery technology plays one of the biggest roles. Today, modern batteries have a much better power to weight ratio than before. This allows RC airplanes and helicopters to stay in the air for a lengthy period of time - even as long as their nitro counter parts, or even longer. Amongst the types of batteries, Li-Po or Lithium Polymer rates as the best your money can buy. While they cost much less than they used to, it is always wise to make sure that your Li-Po battery will last for as long as it could. This article will provide some pointers as to how to store your Li-Po battery for long periods without sacrificing its overall lifetime.
If the Li-Po battery is brand new and you decide to keep it for a while before putting it to first use, contrary to common sense, it is best not to store the battery in its uncharged state. The best practice is to fully charge it and maintain it at 4.2 V per cell before storing the battery away for a long time. For example, if you bought a 3-Cell Li-Po battery rated at 11.1 V, when fully charged, the battery will hold 12.6 V. This will make it suitable to keep stored away for 3 to 6 months. However, after 6 months, the voltage will start to weaken. When this happens, fully charge it again, whereby giving another 6 months of storage time. While this procedure can be performed over and over, the battery shouldn't be kept without being used for more than 2 years.
If the Li-Po battery is fairly new and has been used no more than 70 times, has never reached temperature of more than 45 degrees, and never short circuited, the individual cells within the battery needs to be balanced before storage. This easily can be done through new versions of charger which has a "balance cell" function. Another method is to measure the voltage of each cell and set each cell to have an equal voltage to the least-voltage cell. The cells can be discharged using a simple-circuit light bulb making contact with individual cells, whereby slowly draining out each one. Once the cells are balanced, fully charge the battery, which will give each cell about 4.2 V. By doing this, the battery will be ready for a 2 to 4 month-long storage, upon which time the procedure must be repeated. Please note that ultimately, batteries of this condition stored using this procedure should not be kept for more than 1 year.
For batteries that are in a sorry state, such as having been used more than 70 times and have reached temperature higher than 60 degrees and has been short-circuited plenty of times, the first thing to keep in mind is to not hope for much. The procedure for storing these batteries still remains the same as the procedure above. Balance the cells first then charge the battery fully before storage. However, the result won't be great.
As for the storage, keep the battery in a zip-locked bag and place it in a padded aluminum or stainless container (such as a cookie box). Keep the box away from sunlight and humidity. The reason for the stainless box is to protect your house from fire which may be ignited by batteries short-circuiting. Better safe than sorry right?

6 Tips to Maintain Your Lithium-Ion Battery Pack [battery]
Nowadays, lithium batteries are found in a lot of devices, such as digital cameras, laptops, mobile phones and a lot of other electronic devices. If you want to maintain your battery pack and extend its life, we suggest that you follow the tips given below. These tips will also protect your smartphone and other devices from damage. Read on.
Charge your batteries first
Once you buy a battery pack, make sure you charge it for 12 hours before putting it in your device. As a matter of fact, all manufacturers recommend charging these batteries for at least 12 hours before first use.
Actually, if you have a lithium ion battery, this approach is very important. Unlike the regular Ni-MH Ni-CD batteries, lithium-ion batteries are pre-activated. Since they have a low self-discharge rate, make sure you charge your batteries first.
As soon as the charger gives you the indicator, you can remove the batteries and put them in your device. Here, it's also important to note that these batteries need to go through at least 3 cycles before reaching their full capacity.
Use the right charger
All of us take good care of our electronic gadgets but we tend to ignore the outcomes of using the wrong charger. When you buy a charger, make sure you opt for the original charger. If you can't get the original one, we suggest that you choose a high-quality charger with overcharge protection. Buying a low-quality unit is not a good idea as it may result in shorter run time, battery failure or fire/explosion.
Don't overcharge
Typically, low-quality chargers end up overcharging the battery. What happens is that the substance inside the battery heats up, which may reduce the lifespan of the battery. Therefore, it's better that you fully charge your battery. In some cases, overcharging may cause the battery to explode.
Don't touch the metal contacts
For highest performance, make sure you clean the battery contacts on a regular basis. When you carry the batteries with you, you might want to prevent the contacts from touching metal stuff like your car keys. This is important if you don't want to face a short circuit. If this happens, you may end up damaging your battery. In a worse scenario, fire or explosion can also occur.
Don't use the battery in extreme temperatures
Usually, lithium-ion batteries can work well only if the temperatures are in a certain range. If used in extreme temperatures for a long time, the backup time and useful cycles will decrease.
Don't store your battery without charging
If you leave your battery without charging for more than 3 months, you may cause damage to it. Ideally, in this situation, make sure you partially charge your battery pack before putting it in your drawer for a few months. Ideally, it should be charged at least 30% of capacity.
Long story short, if you are going to buy a lithium-ion battery pack, make sure you follow these tips. By following these tips, you can extend the lifespan of your battery.
