3689 will not work since the 6 would be out of place. 1618 (One road one rich), 1638 (One road to rich for life), 1658 (One Road Fast Rich), 1668 (One road to rich), 1688 (One road to Rich Rich) would work for example as 3 means living... 3689 is not a lucky number as that doesn't really make...
Except that has nothing to do with it. Being Chinese, the number 3 and 8 actually has a special meaning and it has nothing to do with the capacity but more to attract people to buy it who don't care what the capacity is as it's the 3 and 8 that is doing the talking even if it was 380 or 38mAh...
That is the hard part since I already did searching and I have only found replacement batteries, nothing about the pack itself with people replacing batteries.
Thanks HKJ, so literally one can actually make a 7000mAh or 7200mAh pack using the newer 3500mAh/3600mAh batteries that you recently reviewed for example.
The fans are small similar to the small fans used by some laptops and oil won't work but flooding the fan from the opposite side, the moving fan itself, there is usually a small hole and basically you want to flood it with WD-40 as oil seems to not work and then it should work.
Anyone have any good sources for quality Laptop Battery replacements? This is a ASUS A42-G74 battery pack which is 14.4v 5200mAh.
I did find this:
http://www.safebatteries.com/asus-a42-g74-battery.html
which claims to be using Panasonic NNP technology cells and it's 8 cells to get 6200mAh...
It's fully charged according to the manufacturer and the run time is only 2 hours with a 3-4 hour charge daily for 4 days with the power switch off. I charged closed to 7 days.
As in my other thread, they are actually LiIon ICR 18650 Samsung 1800mAh 18650s so the circuit seems to be in the pack. I just know it takes 24 hours of solar charging to get 2 hours of light so putting in higher capacity cells might make the light output last longer.
Thanks for the answers. For custom, need a 2 cell battery pack hooked up in parallel (+ to + and - to -) so it gives double the mAh of the single cell.
