Just a quick question about highest charge current.I just purchased a pair of LGABE11865 cells and an Xtar single bay charger that will do 4.35volts at 2 amps.Would it be safe(or wise) to charge these cells at 2amps or should I be patient and stick to the 1amp charge rate?-Rick
2A is completely fine for these cells, they are very capable of handling high currents.
As well as overcharging - some dude on Fonarevka.ru (Russian flashlight forum) managed to get ~4200mAh out of them by overcharging to 4.7V or so. Not that I would suggest doing that.
Which cell did you buy? LInk?
Google finds nothing for LGABE11865?
I have some pairs of the lGD1 and this is the rating for them:
Less charging current and less end voltage is better for a long life.
What is the color of those battery? I found many LG 18650 in Dell laptop pull but not your reference, maybe they are newer one.
to be really safe and preserve cell longevity, you have to charge at 0.5C, so it has to be 4000mAh to handle 2A charge current.
We can’t know the capacity of your cell as spec are only known to battery pack makers and LG didn’t make a proper site for their battery (unlike Panasonic).
You can charge at 1C but if you have time charge at 0.5C for cell benefit. I doubt that your cell are under 2000mAh so you can charge at 2A.
2C isn't going to light anything on fire but it may decrease the life of your cells. You can see that "maximum" charge is indeed 1C on the D1, which is 2.9A, but the recommended charge is 0.5C. Best to stick to 1A for most 18650s, including the 4.35V LG D1 and E1 cells for maximum life.
Food for thought: those 18650’s are used in laptop battery packs, where they’re charged at 0.7C most of the time.
I was babying my cells when I didn’t knew better, but then I realized that charging at 1A, and charging at 2A, will give me only 5% capacity difference after a year of use - but the saved time difference is HUGE. No more I charge my cells at anything less than 0.7C, and some even above that (e.g. I charge my Sanyo 2600mAh’s in pairs at 6A, which is 3A each, cooled with a 120mm PC fan)
wow are those the new 3200mah 4.35v cells? where did you buy?
go to RMM’s store, Mountain Electronics.I’m only just starting to play with these cells,but I am impressed so far.
I’ve been charging the new LG E1 on the SP1 at the 2A setting.
Takes about 2hr 20min to fully charge from ~3.4V up to 4.33V, love the speed of this charger.
Both LG cells and charger purchased from MountainElectronics.
