1. What is a battery warranty?
Battery warranty refers to the battery manufacturer in order to provide consumers with a guarantee, so within a certain timeframe, the number of battery cycles and battery throughput does not exceed the warranty, can provide free repair and replacement services for your battery, at the same time, usually the manufacturer will also ensure that your battery at the end of the warranty coverage of your battery capacity is at least not less than about 65% of the original battery capacity, for example, a For example, a 10kWh lithium iron phosphate battery will still have at least 6.5kWh of battery capacity at the end of the warranty.
2. What will cause your battery warranty to end prematurely?
2.1 Cycling beyond warranty coverage
The number of battery cycles is the number of times the process of charging and depleting the battery is repeated, because batteries are used differently in different situations, so the manufacturer will provide the maximum number of battery cycles that the battery will have under warranty, different battery manufacturers provide different numbers of cycles under warranty, for example, 500 cycles for lead acid batteries, and 6,000 cycles for lithium batteries, and if your battery exceeds this number of cycles, the If your battery exceeds this number of cycles, not only will the manufacturer not be able to guarantee the performance of your battery, but also the manufacturer will not be able to provide repairs and replacements for your battery in accordance with the warranty agreement.
2.2 The total throughput of the battery exceeds the warranty coverage.
Generally, when a battery is shipped from the factory, the manufacturer will set the total amount of energy that the battery can provide over the life of the battery. For example, if a solar battery with a capacity of 9.42kW can provide 15MWh of energy over its lifetime, then within 8 years of the warranty period, if the total energy provided by the battery does not exceed 15KWh, then you can still enjoy the warranty service. The total throughput can make up for the fact that the battery cannot be fully discharged due to performance degradation, leading to the inaccuracy of calculating the total energy provided by the battery by relying on the number of battery cycles.
2.3 Batteries not installed in the required location
The person installing your battery will install your battery in the specified location before signing the warranty agreement with you. For example, the installer will install your solar panels indoors, but you move the battery outdoors during the warranty period, so that the battery is affected by the environment becomes larger, the performance of the natural decline in the speed of so, so, because you move the battery position during the warranty period, in violation of the warranty agreement, your warranty service will naturally be terminated.
2.4 Natural Factors
Life can be characterized by extreme weather events such as hail, mudslides, earthquakes, hurricanes, and floods, which are factors beyond the manufacturer’s control. This extreme weather may directly damage your battery. In the face of this situation, the warranty agreement will not work.
3. Are labor and transportation costs included in the warranty agreement?
According to industry standards, labor costs are your responsibility, and for shipping costs, some manufacturers may be willing to cover them. Labor cost refers to the cost of reinstalling the battery after it has been repaired for free. Even though some companies promise to install the battery for you, they often add constraints such as “within 30km radius only”. For transportation costs, most companies choose to ship the parts to their sales locations and bring the repaired battery to you on the way.
4. Warranty Duration of Common Batteries
The warranty time of batteries is limited by the use of the battery and the type of battery, for example, usually the warranty time of lead-acid batteries is about 1 year, the warranty time of colloidal batteries is 2 years, while the warranty time of lithium iron phosphate batteries is about 8 years, and the warranty time of nickel-chromium batteries is about 7 years. In life, car batteries, cell phone batteries and laptop batteries are usually lithium batteries, but their warranty time is different, car battery warranty period is usually 5 years, cell phone battery warranty period is usually one year, laptop warranty period is usually 3 years.
Summary
Battery warranty you often need to face in the process of using the battery, I believe that your further understanding of the battery warranty can be your future use of the battery in the process, you can better enjoy the battery warranty service, and then provide convenience for your life.
