Battery Charger Systems - Large

Large battery charger systems manufactured on or after January 1, 2014, shall meet the performance limits in the following table:

Performance ParameterStandard
Charge Return Factor (CRF)100 percent, 80 percent Depth of dischargeCRF ≤ 1.10
40 percent Depth of dischargeCRF ≤ 1.15
Power Conversion Efficiency≥ 89 percent
Power Factor≥ 0.90
Maintenance Mode Power(Eb = battery capacity of tested battery≤ 10 + 0.0012Eb
No Battery Mode Power≤ 10 W
Battery Charger Systems - Small

Effective February 1, 2013, for consumer products that are not USB charger systems with a battery capacity of 20 watt-hours or more. Effective February 1, 2014, for consumer products that are USB charger systems. Effective January 1, 2017, for non-consumer products.

Performance ParameterStandard

Maximum 24 hour charge and maintenance energy (Wh)

(Eb = capacity of all batteries in ports and N = number of charger ports

For Eb of 25 Wh or less: 16 x N
For Eb > 2.5 Wh and ≤ 100 Wh: 12 x N=1.6Eb
For Eb > 100 Wh and ≤ 1000 Wh: 22 x N=1.5Eb
For Eb > 1000 Wh: 36.4 x N=1.486Eb

Maintenance Mode Power and No Battery Mode Power (W)
(Eb = capacity of all batteries in ports and N = number of charger ports

The sum of the maintenance mode power and no battery mode power must be less or equal to: 1x N+0.0021xEb

In addition, TVs manufactured and sold in California must meet the following CEC requirements:   

  • Automatically enter a standby (passive or active) mode after a maximum of 15 minutes without video and/or audio input on the selected input mode
  • Enter a standby-passive mode when turned off by remote or integrated button or switch
  • Have a peak luminance in "home" mode, or in the default mode as shipped, of ≥ 65% of the peak luminance of the "retail" mode, or the brightest selectable preset mode
