One of them is the fact that you can’t investigate the inside of the cell and therefore you can never know if the liquid gels properly. This is the crucial metric for cranking batteries. Even if your battery is unused and new, if it is one-year-old, for example, it will not perform as well as one that has just been delivered from the factory.

If you're asking the question about the difference between deep-cycle batteries and marine batteries, there's a good chance you're thinking not about the 100+ pound, 6-volt deep-cycle batteries, but the more widely-available 12-volt automotive-style batteries that indicate they are designed for deep-cycle use. These batteries have a self-discharge rate of about 3% per month, so their lifespan is not as long as the one of Gelled Marine Batteries. The lead battery plates are what sets the deep-cycle batteries from the cranking ones. If you live in a tropical environment or somewhere that is rarely too cold, CCA, or Cold Cranking Amps, is not so outstanding. It is not that hard to understand what a flooded battery is and how exactly it works. With no maintenance required, you can mount the battery in almost any position as it is sealed and resists against vibration. A deep cycle marine battery, or trolling battery, has several design differences. Then, choose a battery with a higher MCA rating as it is better to have a bit more amperage than you actually need.

Refurbishing and caring for your deep-cycle battery (the type used in marine vehicles and RVs) keeps it working longer. Flooded batteries are really popular as their lifespan could extend beyond 1,000 deep cycles, with the proper maintenance, of course. Choosing a marine battery can be a complicated process. Another disadvantage of using flooded batteries is the fact that they do not handle vibrations well. You must not discharge your battery to below 20% capacity too often, as recharging a flat battery generates accelerated sulfation and heat and therefore, damages the electrodes. The OPTIMA BLUETOP® Battery is a high performance AGM battery with exceptional runtime and more recharges than you would get from a traditional battery. However, most of the cells will need topping-up more often. The term is traditionally mainly used for lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or 'cranking' automotive batteries designed to deliver only a small part of their capacity in a short, high-current burst for cranking the engine. Here are some tips on how to charge it and maintain it too: Chargers 101. Optima 8016 Bluetop Starting And Deep Cycle Marine Battery, 5. Now, this is essential, especially if you decide to get yourself a second-hand battery. MCA is the amount of amperage that is generated when starting the engine, in 32 degrees Fahrenheit conditions.
