Deep cycle battery2/21/2023 This is why no deep cycle batteries list an exact expiry date. The rates of degradation will differ depending on a wide variety of factors, including the storage conditions for the battery itself, external temperature variations, the overall quality of the battery, and the amount it is used. This degradation is an unfortunate, but unavoidable consequence of the chimerical reactions that occur inside batteries when they are running. This is why it is so important to test your deep cycle batteries and make sure they are actually holding a charge.Įven the highest quality lithium-ion deep cycle solar batteries continuously degrade from the moment they are first used. No matter what sort of battery you are using, the performance will diminish the more you use it. 50% lighter) gives them a significant weight advantage over lead acid batteries.Open Mon-Thurs: 10am-6pm & Friday's 10:30am-5pm Eastern Lithium deep cycle batteries can also be 100% discharged without suffering any adverse affects. If you intend to keep your caravan or camper for a number of years, the low cost per cycle makes lithium an obvious choice. Lithium deep cycle batteries are able to deliver a significantly higher cycle life compared to lead acid batteries however their purchase price is also higher. Their unique construction increases their durability and allows them to deliver a higher cycle life compared to flooded batteries. They can be mounted in any orientation because the electrolyte is suspended in absorbent mats rather than a flooded cell. Depending on the usage pattern they may require regular maintenance which comprises of topping up the cells with distilled water.Ībsorbent Glass Mat (AGM) deep cycle batteries do not require any maintenance. Their lower cost makes them a good solution for many applications. There are three main types of deep cycle batteries:įlooded deep cycle batteries are a popular choice. There is no straightforward answer to this question because the lifespan of a deep cycle battery is dependent on various factors such as how deeply it is discharged, how quickly it is re-charged and how often it is cycled along with other external factors such as temperature. R&J Batteries supply top quality deep cycle batteries at affordable prices. Discharging a deep cycle battery by more than 50% will reduce the number of cycles the battery can deliver. As a general rule, a deep cycle lead acid battery can be discharged up to 50% of its rated capacity (i.e. If you were to use a starting battery in a deep cycle application it would rapidly deteriorate from the deep discharging and charging cycle. This more robust construction allows a deep cycle battery to deliver power for extended periods of time without adversely affecting the battery’s health. Deep cycle batteries contain less plates in each cell however these plates are noticeably thicker which increases their durability and dimensional stability. Starting batteries only use a small amount of their overall capacity as they are regularly charged by the vehicle’s alternator.ĭeep cycle batteries are designed to deliver much lower power levels compared to a starting battery however they can deliver this power continuously. To achieve this the battery contains a high number of plates in each cell to increase the surface area available for the chemical reaction to take place. Regular car batteries are known as starting batteries and are specifically designed to deliver short bursts of high power to start a vehicle’s engine.
