How long will agm batteries last
Your climate also impacts the lifespan of your battery If you live in a cold climate or an area where there tends to be a lot of temperature fluctuations, your battery is likely to have a reduced lifespan.
How can you make sure that your battery lasts as long as possible? Compare Battery Types For Marine. Compare Battery Types For Racing. Replacing this lost water can sometimes be an onerous task, but it is a necessary one to get the most out of your battery. Sealed Lead Acid batteries are often referred to as being "maintenance free" or valve regulated. In a sealed lead acid battery the unit is sealed, meaning that water loss is kept to a bare minimum and also that you needn't put any water into the battery.
AGM batteries have a very fine Boron-Silicate glass mat in between the plates inside the battery. The considerable advantage of this type of battery is that they can be operated in almost any orientation and will even function underwater. They will also never leak, even if punctured.
GEL batteries have the electrolyte stored in a gel form; this also won't spill out even if the batteries are broken and also prevents the stratification that other battery types can have.
Gel cells, however, do have some limitations; they take a slower charge than a comparable sized AGM battery. If they are overcharged voids can form in the gel which permanently reduces the battery capacity. For deep cycle applications however the Sealed Lead Acid type of battery can be a great deal more expensive than a comparable Flooded Lead Acid battery.
However, there are times when a sealed battery will better meet your needs than a flooded battery would. Particularly marine applications where stability isn't always a given, and ventilated spaces are hard to come by are often well tailored to a sealed lead acid battery. One other advantage that AGM and Gel batteries have over flooded types is the low self discharge rate.
Generally speaking, there are two different types of lead acid batteries, Starting and Deep Cycle. Also, the self-discharge rate of Sealed batteries is a lot less than flooded lead acid types. How long a battery will last depends hugely upon the way it is used and how well the battery is maintained.
Both overcharging and undercharging will have serious adverse effects on the lifespan of a deep cycle battery. In particular, you can seriously shorten the lifespan of a battery if it is used in a deep cycle application that it was not designed for. An example of this would if you were to use an automotive starting battery as a deep cycle battery. General expectations for batteries if deep cycled these are just approximate guidelines :.
The main things that you can do to ensure you get the maximum value out of your deep cycle batteries are to keep them maintained. The charging is of special importance because both over and undercharging will severely limit the life of your batteries, also if your batteries will see an extended period without being used you should ensure they are routinely checked, cleaned and fully charged before being stored.
Also in some cases, it can be a good idea to put your batteries on a maintenance charge over long periods of disuse. Often the lifespan you can expect to get out of your battery is referred to in terms of "cycles". A battery cycle is one complete discharge and recharge cycle. The lifetime of a battery is directly related to the depth of the discharge that it regularly experiences. Lead acid batteries are fickle things. October September August July June May April Date February 23, Unfortunately, the answer isn't an easy one to provide, because there are a variety of factors that impact how long an AGM battery can last and not all AGM batteries are the same.
For some, the answer could be several more months, for others, the answer could be several more years.
