The typical lasting period is anywhere from 3,000 cycles before it needs to be replaced, but this will vary depending on the usage pattern and age of the battery. Generally, you can expect it to last for about five years before needing replacement if it is not used often or for heavy-duty use like power tools or large-capacity systems. The following factors influence their lasting period.
Its charging mechanism
Typical chargers have a maximum output voltage of 4.2-4.35V, which is higher than the typical market requirements. A lead-acid charger can be used if it does not have an automatic equalization mode that cannot be permanently turned off. If your charger does not have the appropriate output voltage, you will need a step up or step down charger that can provide a higher voltage to the battery (4.4V-10 V). The other option is to purchase a solar panel. Avoid fast charging as high currents will heat and degrade a battery faster than a slow trickle charge. High and low temperatures should also be avoided. Temperature extremes lead to the degradation of almost every battery component.
What are they made of?
A Lithium Ion deep cycle battery is typically made of lithium cobalt oxide and graphite. Lithium cobalt oxide is the cathode, while graphite is the anode. Other cathode materials include lithium manganese oxide, used in hybrid electric and electric automobiles, and lithium iron phosphate. These batteries have a higher energy density than other rechargeable batteries and do not have a memory effect. That means you can charge whenever you need to without damaging the capacity to hold a charge. According to a battery-testing firm Cadex Electronics, a fully charged lithium-ion battery will lose about 20 percent of its capacity after a year of typical storage.
You should store the battery in a cool place and keep it out of extreme heat or cold weather conditions as that will damage the cells. They should also be stored in a well-ventilated, dry area between 40 and 80 degrees Fahrenheit. You should also ensure that it is stored away from sunlight and humidity. You also need to make sure it is not damaged in any way. If you have damaged cells, they may catch fire or explode because they are unstable and can be damaged by physical shocks or punctures. You should also store cells in their original containers where practical. Batteries should also be stacked so that they are stable and will not be bumped, knocked over, or otherwise damaged.
Lithium Ion deep cycle battery is great for powering high-drain devices like laptops, digital cameras, and some flashlights. They are lightweight, and you can charge them when they are partially drained. This is achieved without damaging their capacity to hold a charge. Hence they are very useful in backup power systems. They can be charged by solar panels or other renewable energy sources once the battery is fully depleted. This lifespan is based on the assumption that you are using it in a device and not using it to store energy. If you are using it as a backup power system, you may get additional use out of the battery before it needs replacement.
Precautions to be taken
Never store when fully charged because this will damage the battery and shorten its lifespan. If you do need to charge it, charge it after it reaches 50% capacity so that you do not overcharge it. It would help if you also discharged the battery periodically to use the cells regularly. If you are storing the battery for an extended period, the best thing to do is discharge it. It would be best to clean the battery and terminals before storing them to ensure there is no excess dirt or oxidation. The batteries contain chemicals harmful to humans and the environment if it is incinerated or buried in landfills. They also pose a fire hazard, particularly if there are damaged cells and leak liquid electrolytes.
It is important to note that the lasting period depends on many factors. You need to follow the correct charging mechanism, proper storage, efficient usage, and the right precautions.
