Lithium-ion Batteries: High Energy Density & Long Cycle Life Solutions

A checklist for maintaining lithium-ion batteries includes monitoring the charge level from time to time. To avoid overcharging, use a proper charger that has a cut-off mechanism. The battery should also be kept at a moderate temperature because extreme heat or cold will degrade its performance. Check the battery for any signs of physical damage including swelling or cracks. If the battery will not be used for a long period of time, it is best stored at approximately a 50% charge. It's also important to clean the battery contacts to maintain a good connection
