Battery Maintenance

newtrent support posted this on Apr 9, 2016

Our battery products are very simple device(s) and since they are simple device(s) most people over look the necessity to properly maintain the battery.Our batteries are like every battery product in the market and should be maintained properly to reach its maximum life expectancy.

To prolong the life of the battery a simple charge and discharge done once/preferred twice a week can help keep the cell in the battery in tip top condition.

Though we state a certain charge cycle for our battery (500 cycles), that alone does not define the overall battery life. The major factor that determines the overall battery life is the environment (whether in use or storage: not recommended, explained later).

Here are some tips (in a nutshell) as to how you can maximize the battery life:



– The backup battery is made for charging a given device(s), not as an extended battery pack.

– Try to minimize using the charging device while battery is charging it.

– Keep the battery charge up and try not to discharge the battery completely before charging.

– Do not store or leave the battery unused for long periods of time.

– Do not over charge the unit. (might not be an issue because most of our battery stop charging after fully charging)

– Do not expose battery to high temperature: environment = in car on hot summer days.


the battery is rated with a 500 battery life cycle* and should last 2 years* if properly maintained.

*This is how much the battery can be recharged and discharged number can not be changed and once the unit has gone through it 500 life cycle, the cell has come to a point where it will not be able to hold a charge.


NOTE*. this is the average battery life expectancy but we do not guarantee that it will last the full 2 year and mentioned certain uncontrolled factor can affect battery life. Customer record show some battery lasting 3 years and more so prolonging battery your battery life is possible.


– Our batteries is made to discharge a certain amount of charge to a plugged in device. While is possible to use the battery as a extended battery pack using it this way result in extra stress on battery cells.

– Again like the point before using your device while our battery is charging it will only cause more stress in the battery as it tries to keep up with the device power draw while you using your charging device.

– Li Ion battery do not have a memory affect like other battery type (NiCD, NiMH, etc…) however it best to keep the battery charge up at all time or fully charge it once its low. While the battery can be discharge completely keep in mind this guide is to prolong your battery life so its best to keep battery topped up periodically.

In all scenario do not fully discharge the battery: meaning discharge it until 0%. Under normal circumstances the batteries built-in protection will activate once the battery hits 5-6% and to stop discharging so it will not discharge all its internal charge to charging device. Once the battery has reach this point its advised to recharge battery up back to 100%.

Cases where it will fully discharge to 0% is when the battery is left in storage for long period of time and it slow discharge down to 0%. This is due to its internal self discharge rate and depending on environment (temperature) it can be fast or slow. Once it has discharged to 0% battery will NOT “start-up” again, resulting in a completely dead battery. If it does not discharge to 0% it will still affect the battery if not periodically used.

– So as mentioned in previous point do not store the unit for long period of time as battery may fully discharge. It is for this reason we do NOT recommend storing our batteries or be bought for “emergency situation”, if needed maximum 2 months and no more. Like all things “time” can affect our battery more specifically the cell will be affected and degrade in performance if battery is not used and cells recharged. Perfect example is a car and it battery if car is left un-driven for long periods of time the battery will die, unlike a car battery Li Ion battery once dead can not be “revived”.

– Built in battery protection may prevent battery from over charging but it best to know how long the battery need to be charged and only have it plugged to an outlet for the time need to fully charge. This common practice for all electronic devices for device longevity and safety.

– Avoid extreme heat at all times the cell are sensitive to heat and if exposed to heat the cell internal chemical structure can change and again lead to deterioration/performance of battery. This is the common enemy for all electronic device and one reason why we do not recommend using the 2A to charge small device including smartphone though possible heat may occur (higher output more power = heat) which result in possible smartphone battery deterioration over time.* Another common mistake is leaving battery in car, especially in hot days internal car temperature can reach high enough level to affect battery.


These are the very basic steps and information in keep the battery in working condition. For the duration of the battery life following these step and recommendations can prolong the battery life, but not guaranteed and can avoid unnecessary time wasted RMA your products.
