4 Tips to Extend Your Battery Life:

• Battery Memory - When I first got my new cellphone, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. Allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half
• Battery Calibration - There are some benefits to fully discharging your battery periodically, for laptops this can be especially important. If you start to notice your battery meter becoming more and more inaccurate, it may be time for some battery calibration. Allow your battery completely drain, then charge until the battery is full again. This will calibrate your battery  giving you more accurate readings
• Consequences of Heat - Another enemy of battery life is heat. If you were to leave your laptop plugged in and running for a year, you should expect the battery capacity to be anywhere between 60% to 80% of it's original max capacity. This is why people that use their laptops as desktop replacements will notice greatly reduced battery life performance after one year of use. This issue can be resolved by removing the battery while using a corded power source
• Battery Storage - If you don't plan on using your battery for prolonged periods of time, then you'll want to reduce the charge level to 40% and place the battery in the fridge (not freezer). Storing the battery at 100% charge level applies unnecessary stress and can cause internal corrosion. On the other hand, if the charge is too low, the battery can become permanently unusable, due to battery self discharge

Instruction: 

• Charging the batteries when only a small amount of power has been used is hard on them, and will reduce their life span
• Try to let the batteries completely discharge before putting them on the charger
• Many electronic items, including digital cameras, portable game systems and music players use rechargeable batteries
• The choice to use rechargeable batteries helps reduce chemical waste, and is a cost savings for the user over time
• Rechargeable batteries are used for flashlight
• The pictures of our Battery are real and if there is something tinny difference, please ignore 

NOTE:

• Do not disassemble, short circuit or dispose of in fire
• Do not mix with different battery type
• Strongly suggest you use the protected battery for it can really protect your battery well and extend your battery life as well as avoid the over-charging and over-discharging of your battery
• We are not responsible for the broken of the battery and charger for your users' wrong using methods 
• Rechargeable batteries that have been in storage for weeks or months will lose power and need to be recharged before being used
