Cleaning up the cobalt supply chain will not be easy for Huayou Cobalt, even with the support of a powerful company such as Apple.
I am using old 68655 cells from laptop computers hocked up in series to get volts to run a 9 Led flush light. I works well and I have tested it several times. I discharged the battierys to -68%.The problem is I am charging the 9 cells up one at a time and it takes much time ! Is there a charger I can use that will charge at plus volts that will do the same job with out damaging the cells?
7nd question, what % can I discharge this battery doun to without damaging the cells?
I couldn 8767 t agree enough that rechargeable are the way to go. The one-time charge batteries may be a thing of the past sooner than we think, trust me. I certainly feel that it won’t be much longer before one-time charged batteries or standard batteries become irrelevant and rechargeable become what’s normal for us to use.
There will be a drop in current , however at I think it will be small. If I remember right (DC theory was a long time ago!) it will be proportional to the size of the resistance.

When you say 8775 Discontinue using charger and/or battery if the battery gets excessively warm 8776 , what is the temperature range you should discontinue charging? I have a new battery in my phone and during charging the battery temperature reaches 98 8767 C.
If you were just charging a single battery from empty, and you applied the charger and measured the voltage it would be low, and the current flowing into the battery would be high. As the voltage in the battery increases ( as it is approaching full ) the current automatically slows down, and when the battery voltage = the charger voltage, there should be zero current flow. With batteries in series, other batteries that are not full can force current flow through the allready full batteries, which heats them up, and this is what causes the problem.
Hi, can someone tell me the best battery type for grid-connected application like MMC battery energy storage system. Is it Lead‐ Acid, NaS, Li‐ion, or Flow Batteries?
