Different vehicles and driving styles can place varying demands on your battery. Learn about the difference between deep-cycle and starting batteries. These batteries deliver a large burst of power for a short time as needed for normal engine starting.
The battery is then recharged by the alternator. In a lithium battery , the electrons move back and forth from anode to cathode to create a charge in a solution of lithium salts. This deep cycle battery can be almost completely discharged without consequence and their recharge rate is the fastest of any battery type.
They are about half the weight of lead-acid batteries. All these points make them some of the best RV batteries for boondocking. Charging of lead-acid batteries takes place over stages, leaving room for problems like overcharging or undercharging. They are usually the least expensive option for a house battery and can be recharged numerous times, but sometimes have a shorter life than AGMs and lithium batteries.
Like AGMs, these deep cycle batteries are maintenance-free. They transfer electrolytes through a gel substance created by sulfuric acid and silicate. You will find these batteries used in electric wheelchairs and scooters. These deep cycle batteries have fiberglass between the plates in their cells for the electrolytes to pass through. Their recharge rate is much faster than a lead-acid battery but not as fast or efficient as a lithium one.
All deep cycle battery types, with the exception of lead-acid, do not require any maintenance. However, distilled water must be topped off in lead-acid batteries monthly to keep the plates in each cell submerged. Failure to do so will render the plates useless and the battery will have to be replaced. If you will not be using the batteries for long periods of time, a trickle charger can be attached to lead-acid and AGM batteries to keep them charged.
You do not need to use it on lithium batteries, as they have their own internal battery management system.
Make sure you clean your batteries and ensure there is no dirt or debris that will build up on the battery terminals and hinder their effectiveness. Physically inspect your battery if the are any cracks or if the battery has bulged out.
Bulges and cracks indicate problems like freezing, lack of battery fluid or a problem with the alternator. The easiest way to prevent all this is to wipe the battery with a paper towel. Deep cycle batteries should have their fluid level checked.
They should be watered with distilled water after charging except if the plated were exposed before charging. Shallow discharges should be made to prolong the life of your battery. Ultimately, this will end up in a shorter battery lifespan. If you are going to be using multiple batteries, you have to ensure that they are all of the same size, age, and usage level otherwise you will face some problems.
If you replace one battery with a new one, the other older batteries will drain the newer one to their level since they cannot keep up with it. If you need to test sealed batteries then you will need a load tester, otherwise, test your battery, you will only need a DC voltmeter and a hydrometer. Batteries lose charge with time and so leaving them inactive for several months could result in them passing their threshold of discharge.
Charge it at least once a month to keep the voltage up in warm weather, but in cold weather , you can go months between charges. You will have to change your battery maintenance routine with time.
With time there is more use, wear and tear, and exposure to detrimental factors. And thus, older batteries will need more care and you will have to keep that in mind. Ensure you use the right sized charging source for your battery. An over-sized charger will result in excess gassing, thermal runaway, and even explosions. First, you need to know that after you have bought battery you will have to charge it.
Also, please use the right sized charger as mentioned above. Now follow the steps below:. To determine how long a deep cycle battery lasts, you have to keep in mind several factors. All these and more culminate to your overall battery life. But with vigilant care, you can have your batteries for well over 5 years. I have two cars that have been completely upgraded with my own hands.
