Deep cycle battery, on the other hand, have much thicker plates and, they are solid, not sponge.This sort of arrangement means that the plates have much more surface area in the solution than a Deep Cycle battery and allow them to draw larger currents much quicker than a Deep Cycle battery. In a starting battery, you will find more lead plates, thinner and often made of a lead “sponge” similar looking to a foam sponge. Starting batteries are generally designed to start some form of an internal combustion engine (car, truck, boat, etc).The same starting battery will last for thousands of cycles if it is just used normally (2% – 5% discharge). If a starting battery is routinely deep cycled (discharged below 20%-50% of max capacity), it will generally fail after 30-150 cycles.

Generally speaking, there are two different types of lead acid batteries, Starting and Deep Cycle. What are the differences between a starting and deep cycle battery?

Require BMS for protection, most lithium batteries include an internal BMS.

Cannot be charged at low temperatures, near freezing or below.

Some lithium-ion chemistries are thermally unstable, can overheat and catch fire or explode.

Most expensive up-front cost, may be lowest lifecycle cost of all types.

Can be stored at low state-of-charge with no damage.

Very light, very compact (half the weight of lead-acid).

Very low self-discharge, 1-2% per month (lowest if stored partially-charged).

Very little power loss at low temperatures.

AGM cells are sealed, so do not off-gas with typical use and charging.

Electrolyte is only in saturated glass mats, so will not spill.

Accept charging at much higher rates than lead-acid or gel.

Require their own specific charging profile, different than AGM, lead-acid or lithium.

More costly than flooded lead-acid and some AGM.

Gel cells are sealed, so do not off-gas with typical use and charging.

Gelled electrolyte (silica added) does not spill as easily as flooded lead-acid.

Destroyed by freezing (case bursts, electrolyte spills).

Must be stored fully-charged to avoid damage.

Low cycle life, often 300 to 500 cycles.

Require maintenance – monthly top-off of electrolyte.

Can be left on trickle or float charge for prolonged periods.

Indefinite shelf life if stored without electrolyte.

Robust – tolerant of abuse and overcharging.Reliable – continuous refinement since 1860.A hybrid marine battery can offer both a starter burst and sustained power for marine applications, but tends to have a shorter lifespan than a battery with a dedicated role. Materials handling, including forkliftsįor some applications, particularly marine uses, hybrid batteries are another solution.Some of the most common uses for deep cycle batteries include:

When to Use a Deep Cycle Batteryĭeep cycle batteries provide sustained energy, making them ideal for certain applications that require more than a quick start. To be specific, a starter battery discharges only a tiny percentage - usually 2 to 5% -each time it is use. The level of discharge is the “deep cycle” and stands in contrast to other types of batteries that provide only short bursts of energy before they need to be recharged. It is important to note that although deep cycle batteries can be discharged up to 80%, most manufacturers recommend not discharging below 45% to extend the life of the battery. A deep cycle battery is a lead battery designed to provide sustained power over a long period and run reliably until it is 80% discharged or more, at which point it needs to be recharged. What are deep-cycle batteries? These are batteries whose design is optimized for regular deep discharges of power, perhaps even at very rapid rates by power-hungry appliances like induction cooktops, microwave ovens, RV air conditioners and RV refrigerators.ĭeep cycle batteries, may look a lot like car batteries to people who aren’t familiar with them, but in reality, they’re quite different. These batteries will provide the dependable power you need under any conditions, something you’ll be grateful for at the end of a long road in the middle of nowhere. Power for instruments or equipment at remote sitesįor an RV, it’s essential to have proper deep-cycle batteries for your battery bank.Off-grid energy storage systems for solar power or wind power.

Industrial forklifts and floor sweepers.

Trolling motors for recreational fishing boats.

Other marine use, especially on a sailboat lacking power generation capability, generally smaller vessels.

Cathodic protection, which might include marine use.
