Quick Answer: What Is The Difference Between A Marine Starting Battery And A Deep Cycle Battery?

What is the difference between a deep cycle battery and a starting battery?

A deep cycle battery is constructed differently than a cranking battery, with thicker, heavier plates.

The cranking battery has more yet thinner plates to give a fast voltage spike to crank an engine, but is not intended to maintain high power output for long periods..

Should you trickle charge a deep cycle battery?

Some lose energy quicker than others, which is the purpose of a trickle charger. Deep-cycle batteries do not need to be at 100% to be used, although fully charging the battery after use extends its lifespan.

How long should you charge a deep cycle battery?

Depending on the physical size, a “deep cycle’ battery may have 80+ “amp hours” (1 amp per hour at 80 hours) of storage capacity. So to charge a deep cycle battery at 2 amps from a “discharged state”, would take around a couple of days (48 hours).

How do I know if my battery is deep cycle?

If the battery specs mention “starting”, or ” cranking” or list a CCA (Cold Cranking Amps) number, then it is surely not a deep cycle battery. At best it is a cranking/cycle performance hybrid. That is often seen in marine batteries which are expected to power running lights and accessories when the engine is off too.

Is a marine battery better than a car battery?

Quality deep cycle marine batteries will have a reserve capacity (RC) rating that indicates how long the battery will operate before losing power. Marine batteries are also capable of more frequent and deeper discharges than car batteries.

Is it better to charge a battery at 2 amps or 10 amps?

A basic charger usually charges at around 2 amps – and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market – from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.

Can you use a deep cycle battery as a starting battery?

You can use a Deep Cycle battery as a starting battery provided that you take into account the lower CCA of a Deep Cycle battery. As a rule of thumb, it’s a good idea to upsize the battery by about 20% to deliver the same amount of cranking amps from a deep cycle battery.

What happens if you overcharge a deep cycle battery?

Overcharging Deep Cycle Batteries: As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.

What type of battery is a marine deep cycle?

The thicker battery plates resist corrosion through extended charge and discharge cycles. Deep-cycle lead-acid batteries generally fall into two distinct categories; flooded (FLA) and valve-regulated lead-acid (VRLA), with the VRLA type further subdivided into two types, Absorbed Glass Mat (AGM) and Gel.

What is the longest lasting marine battery?

Runner-Up, Best Overall: VMAX XTR31-135 AGM Marine Battery This battery has superior plates and a float service application lifespan of 10 to 12 years. Ranked as a Group 31 battery, it measures 13” x 6.8” x 8.4” and weighs 77 pounds.

How long does it take to charge a deep cycle battery at 10 amps?

15 hoursFor round numbers takes a 150 amp deep cycle battery. Charge it at 10 amps, you will need to charge that battery for up to 15 hours to fully charge as it puts up to 10 amps in each hour.

Is there a difference between deep cycle and marine battery?

A deep cycle marine battery, or trolling battery, has several design differences. One key is plates: It has fewer, thicker plates allowing the battery to provide continuous power output over long time periods. Deep cycle batteries can be entirely drained and recharged many times over, cranking batteries can’t.

What makes a marine battery different?

Marine units feature thicker internal lead plates than their automotive counterparts, which allow them to discharge energy over a longer period of time. … Finally, you can identify a marine battery by its use of “marine cranking amps,” or MCA rating, instead of the standard automotive “cold cranking amps” (CCA).

What amp should I charge my deep cycle battery?

It is better to charge a deep cycle battery at a higher charge rate like 6-amps, 10-amps or higher. However, check you battery specifications for the proper charge rate.

What is the advantage of a deep cycle battery?

Lighter and smaller than flooded lead-acid batteries for the same capacity. No regular maintenance or topping-up required. Low internal resistance allows very fast charging, with reduced energy loss. Sealed case allows batteries to be used, stored or transported in any orientation.
