The manufacturer of deep cycle batteries aims at ensuring that their batteries withstand discharging within a period of time.
Deep cycle batteries aren’t like other types of batteries. They have the capacity of providing a higher burst of charge, for example, using for cold starting.
Mostly, you are likely to come across these deep cycle batteries on RV house batteries or use them with golf carts. It is needed in places where power is required but not used in giving powerful starting bursts.
On the other hand, if you want to charge a deep cycle battery, the instructions are describe on https://www.trollingbatteryguides.com/best-marine-battery/ and also mention below, but you also have to keep in mind some essential tips:
First, start by disconnecting your deep cycle battery – when necessary. For stored batteries, they might not be connected with anything. When you pick your deep cycle battery, take it to a clean and dry place with proper ventilation.
In the next step, you need to have a flat screwdriver. You will use it to remove the battery cells covers for you to confirm the level of electrolyte in each cell.
In case you have a sealed deep cycle, it’s also easy to remove your cell cover. These covers are either one large-cap covering all your battery cells or individual cell plugs.
After opening the cell cover, insert your hydrometer’s tip inside the cell that will draw fluid inside the hydrometer. You can read your hydrometer instructions.
Depending on the hydrometer you have, some have a floating ball that helps to indicate whether the cell water level is low while others will be having a needle gauge.
There is the necessary level of water that supports the electrolytes in your battery and also allows it to function correctly. After testing each cell, you can recap the cells.
Depending on the size of your deep cycle battery you want to charge, you can set the battery charger to a trickle or slow charge.
In case your battery is having a charger and with an option of setting charging voltage, you should set into 20% of the rating of your battery you’re are charging.
If you want to know about an amp per hour of your battery, it’s usually on the side or top of your battery. These types of batteries charge the best while having the lowest charging flow.
Start connecting the charger cables to battery terminals. You have to ensure that while connecting, you start with the positive terminals. These codes have their specifications, either having a plus sign or red color or a cover. When done, start connecting the positive cable that has a minus sign to the negative terminal.
When you have connected, turn the charger on. After a period of 20 minutes, you can check at the charge meter. It’s this time that the charger needs to give an accurate reading.
If you will have a voltage regulator, leave your battery and remove it at your convenience. The regulator will help to shit down the charger after battery getting the correct voltage.
