Deep cycle batteries are a kind of batteries specialized in multiple deep discharging and recharging, which are widely used in many fields. The service life of a deep cycle battery is closely related to the charging method. Charging a deep cycle battery can be roughly divided into 5 steps, and the following are the specific steps for charging a deep cycle battery:
First of all, take out the special charger for deep cycle battery, use the charger to connect the positive and negative terminals of the deep cycle battery with the power supply, there can’t be any wrong connection of the positive and negative terminals, or it will lead to short-circuit and scrap of the battery.
For some power supplies you need to use a voltage regulator to adjust the voltage parameters in the circuit. For example, if the output voltage of your solar panel is 24V, then you can use the voltage regulator to convert the voltage in the circuit to 12V to ensure the normal charging of the deep cycle battery. Therefore, you need to confirm the charging voltage and charging current before charging your deep cycle battery.
The charging process of a deep cycle battery is usually divided into three stages, which are based on the battery’s charge, including the initial charging stage, rapid charging stage and float charging stage.
Initial charging stage refers to the battery’s power is very low, probably between 0% and 10%, at this time you need to charge with a lower current, if the charging current at this time is too large will lead to a rapid accumulation of heat, resulting in overheating of the battery, which will damage the internal structure of the battery, especially lead-acid batteries, overheating environment will lead to the rapid evaporation of the electrolyte, resulting in the corrosion of the pole plate, so the initial charging stage should be used with a smaller Current.
Rapid charging stage refers to the battery’s power has been restored to a certain level, probably between 10% and 90%. At this time the chemical reaction inside the battery is more active, and as the charging process proceeds, the resistance inside the battery will decrease. All of this ensures that the battery can be safely charged at a higher current, so in order to shorten the charging time, you can use a higher current to charge at this stage.
The float charging stage means that the battery is close to being fully charged, probably between 90% and 99%. Float charging refers to a process of charging at a lower current. This charging method not only reduces the heat generated by the battery and puts the battery in a safe state, but also prevents the battery from being overcharged, which can damage the battery and reduce its service life. Especially some need continuous power supply environment, such as the caravan traveling process, float charging can ensure that the battery is in a fully charged state, but also to avoid overheating of the battery.
During the deep cycle battery charging process, the battery’s monitor will report the temperature, current and voltage of the battery to you via your mobile app, which you need to keep an eye on to ensure that the battery is in a safe charging state. If your battery is not equipped with a battery monitor, you need to keep an eye on the battery charging status.
Once the deep cycle battery is fully charged you can disconnect the charger. However, for those deep cycle batteries that are connected to a power source for a long period of time, there is no need to disconnect the charger, but make sure that the battery is on a float charge so that the battery is in a safer condition.
You need to pay attention to many aspects, for example, you need to check the battery condition regularly, no bulging or leaking, and then you need to use the right charger and follow the charging instructions strictly to charge your deep cycle battery. Correct charging habits can extend your battery life to a certain extent.
There are many power sources to power your deep cycle battery, such as alternators, shore power, solar panels and turbine generators can power your deep cycle battery, of course, you can also use rechargeable batteries to charge your deep cycle battery.
Take solar panels to charge your deep cycle battery, first of all, according to the basic parameters of the deep cycle battery, including battery capacity, battery voltage and battery current, choose the right solar panel with the right output power, then make sure that the charging environment is suitable, for example, you can’t put the deep cycle battery under the sun, which is not conducive to the dissipation of heat, and then correctly connected to the charger, then you can charge your deep cycle battery! The charger can then be connected correctly to charge your deep cycle battery.
To summarize, no matter which power source you choose to charge your deep cycle battery, make sure the charging process is correct. In comparison, solar panels are one of the best options for powering your deep cycle battery, both in terms of safety and cost, especially for motorhomes, so you may want to give it some thought.
By knowing more about the charging process of deep cycle battery, you can charge your deep cycle battery correctly, so that your deep cycle battery will have stronger performance and longer service life, I believe that the deep cycle battery can surely provide a help for your daily life, now, charge your deep cycle battery.
