Lithium-ion batteries generally have a longer lifespan than lead-acid batteries. They can be charged and discharged more times and have a lower self-discharge rate. Lead-acid batteries typically have a lifespan of 3-5 years, while lithium-ion batteries can last up to 10 years or more with proper maintenance.
failure occurs at a point in time during the test before 90%-95% of the expected test time has been reached. It is permitted once during a test. The downtime cannot exceed 10% of the total expected test time or 6 minutes, whichever is shorter, and this downtime shall not be included in the test discharge period when calculating battery capacity.
