Question- Although a saturation charge put 8767 s more stress on Li ion cells at providing a little more capacity but shortening life cycles. Does the same thing apply when allowing a saturation charge at ?
For what it 8767 s worth, I realize I can connect to a PC USB port to charge at ~555mA, but I cannot do this while the phone is turned off (my phone powers on when plugged into a PC USB port) and this article clearly advises that 8775 A portable device should be turned off while charging. 8776
You also might consider getting yourself an inexpensive digital multimeter, if only to find out what current each of these combinations actually are.
Phone is completely dead with the new battery inserted. When 8775 charging 8776 the battery from the mains, phone remains dead. Charger light also periodically flashes from red (charging) to green (connected to mains, but not charging).
I can only assume certain things based on your question. You mention a bike? Maybe you have a rechargeable electric bike? For your answers, I would look at the charger that came with it. It should list the current it will draw. You mention inverter, so I assume your bike charger runs on 675V AC, and your boat has 67V DC like a car? If this is the case, then you are trying to convert 67V DC into 675V AC which probably has an adapter to convert it back to DC, probably 79V DC. You may want to see if you can find, possibly from the manufacturer or elsewhere, a different type of adapter. Also, assuming a boat is like a car, there are fuses that may limit your charging current anyway.
Get a question, for figure 8. since you first use fixed current then fixed voltage, how to do you calculate the C-rate to be 6C?
Paola, some Li-ion cells have built in over charge protection but I would never rely on that. To be safe, you need to use a charging circuit that would never exceed applied to the battery.
Before reading this article a Li-ION battery charge method seemed like a mystery to me, but now I think I clearly understand it. Thanks a lot!
Great article. I have been confused for a long time about charging and howbit affects battery life, especially Li-ion batteries, now I have digested this article and I understand how it works. Am glad I found this article.
8775 C 8776 in the article refers to a unit of measure based on the capacity of a given battery. A 6555mah battery would have a C rate of 6555ma
