Hi, i have recently tested few aftermrket batteries for capacity and they are having awefull capacity .. i am using opus battery analyzer.
i tested using opus c3100. below are my tests
1: Nokia BL-5CB 800mah battery after 2 years of use had 763 maH capacity.
2: A Chinese BL-5C stating to be 1070mAH supposedly high quality ( Tely brand ) battery turns out to be 750mAh : Cost 400 Rs
3: Two other Chinese after market supposedly 1200mah high quality batteries for samsung s5570 were tested one was 750mAH ( costing 400 rs ) other 570maH (costing 600 rs) charging and discharging was done at 300ma current.
anyone who had luck with some real capacity batteries ? btw if anyone wants to test their battery they can contact me. i will test the real capacity for free and fun to share with other users.. as their is a dearth of information due to which shopkeepers are minting a huge amount .. these batteries shouldnt cost more then 100rs at retail considering 2600mah real panasonic cylinderical cost 300 rs along with shipping cost form china... also if you buy xiaomi 10400mah bank you get four 18650 batteries along with world class battery maangemet system for 20 usd along wiht shipping cost from china ..prismatic shouldnt be that expensive.
here is my thread about it.
