lithium batteries are everywhere these days, used in everything from cellphones and laptops to cordless power tools and electric vehicles. As time goes by and frequent use, many lithium batteries may experience some level of degradation. It will directly shorten batteries lifetime! Learn how to extend lithium battery lifetime by considering battery chemistry, depth of discharge, temperature, and capacity termination level.
Tritek has been specialized in LEV battery packs researching and manufacturing since year 2008. After our experimental verification several times on LEV lithium battery packs, Tritek is more convinced that proper care will extend lithium battery lifetime. What is the proper care including? Usually, a combination of several factors increases or decreased battery lifetime. For increased cycle life：
BMS helps to extend lifetime
Battery management system (BMS) effectively monitor the state of the batteries and battery cells, preventing overcharging and discharging that may reduce the battery lifetime, capacity and even cause explosions. A BMS checks the power voltage, and when the required voltage is reached, it stops the charging process. In case any irregular pattern in the power flow is traced, BMS shut down and send out an alarm. It won’t affect the PCB or cells so that prolong the battery’s cycle life. In addition, they regulate the temperatures of the battery cells, and also the battery’s health, making it safe and reliable under all conditions.
Temperature range during charging
The recommended temperature range for battery charging is between 0℃ and 45℃. Charging of the batteries out of that temperature range will cause the performance of the batteries to decrease and their life to shorten.
Never 100% discharge the battery
When the batteries are not to be used for a long time, please store them safely so that they will stay in a half-charged state. Please wrap the batteries with non-conductive materials in order that metallic materials will not contact the batteries directly, which may result in damage to the batteries. Keep the batteries in a cool and dry place.
Recharging battery per 3 months
Charge the battery every 3 months (keep state of charge over 50%) at shelf time; charge the battery in 1 week after over discharged while operating, to make sure the battery is in a healthy state.
Do not disassemble the batteries
There are a protective mechanism and a protective circuit inside the battery, which helps prevent danger. Improper disassembly of the battery can damage the protective function of the battery and therefore causes the battery lifetime reducing.
Short circuit of battery is prohibited
Do not short circuit the positive and negative poles of the battery with metal and do not store or move the batteries together with metal sheets either. If the battery is short circuited, a heavy current will run through the battery, which will damage it and cause it to heat, smoke, deform and even burn.
Damping of the battery is prohibited
Do not moisten the battery and throwing of the battery into water is even more prohibited. Otherwise the inner protective circuit within and the protective function of the battery may be lost and abnormal chemical reactions may occur, and as a consequence the battery will shorten the cycle life, even accidents caused, such as: heat, smoke, deform or burn.
Charging with matched chargers
It is recommended that batteries should only be charged with a matching charger, otherwise, the inner protective circuit within and the protective function of the battery may be lost and abnormal chemical reactions may occur. Remember not to place the batteries in the charger for over 24 hours.
Damaged of battery is prohibited
The battery should not be damaged by means of methods like knocking metallic things into the battery, hammering the battery, knocking it violent or etc. Otherwise the battery may heat, smoke, deform or burn and even dangers may happen sometimes.
Caring charging duration
If the charging process takes longer than usual, the battery may be damaged. In this case, stop charging immediately. Have the battery and charger checked by your retailer to prevent further damage. Professional examination and maintainence will keep battery packs in good cycle life.
lithium batteries are a huge improvement over previous types of batteries. Getting good performance with a good cycle life from a lithium battery is not unheard of. Please trust Tritek’s over 12 years experience of LEV battery pack manufacturing, please follow the above guidelines to extend your e-bike/ e-scooter/ motorcycle battery packs lifetime,
