Fast or Slow Charging Lithium Li-ion 3.7V Rechargeable Batteries
We've been asked several times about charging Li-Ion batteries, which Charging Current (CC) is correct and if 0.50Amp charging can prolong battery life and keep the battery in good condition.
Not really :-) it depends on capacity and size of each battery. We recommend the use of chargers with CC/CV.
Firstly, we need know the batteries standard Charging Current (CC) specified by the datasheet of battery/manufacturer/seller - these basic specs are often not available.
As standard we can say 0.5C CC, meaning 0.5x battery capacity, for classic Lithium batteries unless a different specific CC is supplied by the manufacturer.
Recommended CC are :
0.25A CC- 0.50A CC for small size batteries : 10440/AAA , 16340 / CR123, 14500-AA , 18350 , 14650 (capacity below 1000mAh)
0.50-0.75A CC 16650 , 18500 , 17500 , 18650 as well (mostly low capacity batts below 2000mah)
all new (last 2-3 years) 18650 , 26650 IMR , INR and as well ICR/NCR's is standard 1A CC and some slightly more as well, it’s always best to check the datasheet when available.
20R - 1A Standard , 4A Rapid
25R - 1.25A Standard , 4A Rapid
HE4 - 1.25A Standard , 4A Rapid
HG2 - 1.5A Standard , 3A Rapid
HB6 - 0.75A Standard , 4A Rapid
30Q - 1.5A Standard , 4A Rapid
VTC4 - 2A Standard , 4A Rapid
VTC5A - 1.30A Standard , up to 6A Rapid charge
VTC6 -Standard 2A , up to 5A Rapid (6A Pulse )
Sanyo GA 3500 1.45A Standard , Rapid not specified
Panasonic NCRB or Sanyo BF 3400 1.625A Standard
All 26650 can be done with 1A , 2-3A is standard
The CC also depends on charging conditions, lower tempearature - better use lower CC , by standard room conditions go to Standard Charging Current .
