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.

--Operating Costs. Lithium iron phosphate (LFP) batteries are the most economical batteries for emergency lighting. This is because the primary replacement for NiCd batteries has a high self-discharge rate (about 20% per month) and therefore must be constantly recharged to be ready in the event of a power outage. In contrast, LFPs have a much lower self-discharge rate, which means that the charger can only be used for a short time every month or two. Based on tests conducted using commercially available emergency bulkhead accessories with NiCd and LFP batteries, the following power consumption data was recorded.

LED emergency bulkheads were used to compare the power consumption of NiCd and LiFePO4 batteries.

In summary, the use of LFPs instead of NiCd in popular emergency light fittings resulted in >40% power savings.

On the financial side, assuming an electricity price of £0.145 per kWh, the savings are £2.25 per emergency light fitting per year.

--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.
