Advantages of LiFePO4 Battery:

What is the cost of using lithium iron phosphate (LFP) batteries in emergency lighting?

Lithium iron phosphate is very cost effective as an emergency lighting power source compared to alternatives such as NiCd. This applies to its acquisition cost, operating cost and maintenance cost.

-- Acquisition Costs For more than four years, the acquisition cost of lithium iron phosphate (LFP) batteries for emergency lighting has been lower than the cost of NiCd batteries. When compared on a capacity (Ah) basis, lithium iron phosphate batteries are more expensive than NiCd batteries. However, because the performance of NiCd batteries degrades relatively quickly during their service life, more batteries are needed to provide the expected 3-hour duration after 4 years of use. In addition, LFP cells are expected to last twice as long as NiCd cells, so the acquisition cost of LFPs is lower than NiCd over 4 years or more.

--Maintenance costs. Lithium iron phosphate (LFP) is less expensive to maintain than alternatives such as NiCd. This is because the NiCd batteries used in emergency lighting are typically designed to last only 4 years. Comparable lithium iron phosphate batteries have an expected life of 8-10 years.

LiFePO4 Battery Performance and Test Conditions

1. Standard test conditions

Test should be conducted with new batteries within one week after shipment from our factory and the batteries shall not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done under temperature of 20±5℃ and relative humidity of 45~85%. If it is judged that the test results are not affected by such conditions, the tests may be conducted at temperature 15~30℃ and humidity 25~85%RH.

2. Standard Charge/Discharge

Standard Charge: 0.2C

Charging shall consist of charging at a 0.2C constant current rate until the battery reaches 14.6V. The battery shall then be charged at constant voltage of 14.6 volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 0.05CA. Charge time: Approx 7.0h, The battery shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.

Standard Discharge: 0.2C

Battery shall be discharged at a constant current of 0.2C to 10V @ 20º ± 5C
