Q: can i use it as my laptop cell? Questioned by rumon2071, 06-Jan-2019

No. This one has quite low mah compared to laptop batteries. If you use these, you'll have a low back up time. Answered by A.R, 07-Jan-2019 03:35 AM

Q: Can I make Power bank with this battery for my mobile phone?? If I made the power bank for 10,000mAh capacity, So How much Battery can I use? Questioned by Tutulbdmax, 24-Jan-2019

This is suitable for power bank. According to our testing these are about 1500mAH. So, you can use 7 batteries in parallel. Answered by A.R, 27-Jan-2019 03:44 AM

1st you said you got 3000mah. Now you are saying 1500mah! Please be sure before replying. It’s confusing! Answered by mahmud7045, 27-Jan-2019 08:45 AM

in devices like cell phones, 0% battery means about 3.2V. So, if you drain the battery to that voltage from 4.2V, you'll get about 1500-2000mAh. But if you drain the battery fully to 0V, it will give about 2500+ mAh. Hope you've understood. Thanks Answered by A.R, 28-Jan-2019 03:38 AM
