People who use recreational vehicles, such as golf carts, wheelchairs, vessels etc, will know a thing or two about deep cycle batteries. A deep cycle battery is different from automobile batteries. They should give off most of their charging capacity during each cycle and supply power for a longer duration. Because of the distinct capabilities of deep cycle batteries, special care and attention should be provided to extend their longevity.
Here are some useful maintenance tips provided by a recognised supplier of high-quality deep cycle batteries:
Always Check the Charge Level of the Battery:
When your deep cycle battery is being used to power something, you must always check the charge level so that you do not lose power in the middle of nowhere. Deep cycle batteries discharge approximately 45-75% of their capacity, depending on the brand.
So, how can you find out the amount of charge left in the battery? There are several instruments available to assist you, such as digital voltmeters or hydrometers. Use any of these to see the current charge of your battery. The key is to recharge the battery at 50% and not let it go lower than 20% to help prolong its life.
Try and Avoid Stratification:
When your deep cycle battery is partially charged or discharged frequently, stratification takes place. This will impact both the battery capacity and performance. Stratification disrupts the chemical balance inside your battery, and the mixture will become ineffective. Stratification can be resolved with mechanical stirring of the electrolyte and regular running of the battery. Try to avoid or minimise rapid charging and discharging of the battery to maintain optimal performance.
Allow Your Battery to Cool off:
If you use your battery frequently and recharge it, it's a good idea to let the battery rest until it cools down. If you start using your boat or wheelchair immediately after a full charge, you risk burning out your battery. Making it work right after charging is a bad idea since it can cause grid corrosion, which further leads to total battery failure. Cooling down your battery after charging is really important.
Beware of Sulfation:
Deep cycle batteries are prone to sulfation if not charged often. When the battery remains inactive for a while, the lead will crystallise and your battery can accept a charge no more. Once this happens, it's usually too late to save the battery since the sulphate deposits will damage the battery plates and make them not work at all. Maintaining or following a periodic battery cycle will keep your deep cycle battery safe and healthy.
Equalisation is Important:
Following a regular charge cycle, cells require equalisation to stay in balance. This is made possible by giving a low current charge after a charge cycle. Keeping the cells balanced is critical for deep cycle batteries otherwise it leads to battery failure.
