are all marine batteries deep cycle
*Not all marketed Deep Cycle batteries are in fact Deep Cycle batteries. The vast majority of 12V flooded batteries sold as Marine Deep Cycle are not really what I would consider a deep cycle battery. I often refer to 12V flooded deep cycle batteries as light cycling or pseudo deep cycle batteries. You can count on the power of OPTIMA starting and deep-cycle batteries. Specifically designed for marine use, an OPTIMA battery lasts longer and starts reliably, even after infrequent use or off-season storage. « All Marine Batteries. Interstate® carries a wide selection of dual purpose starting/deep-cycle batteries that can meet all your marine power needs. They'll consistently start your engine to get you where you need to go, and power all your electric needs along the way. With Interstate, you have the power to go anywhere. Group 24, 27 & 31 & most *4D & *8D flooded 12V Marine Batteries are NOT really a deep-cycle battery when compared to a battery specifically designed from the ground up as a deep cycle battery. Simple stuff. There are 6V and 12V batteries that are much better suited to cycling duty than Group 24, 27, 31 etc. batteries. Deep Cycle Marine and Boat Batteries - Formats. 12 Volt deep cycle batteries are specifically engineered for heavy charge/discharge cycling; perfect as a house battery or running a trolling motor, depth finder, live well pump, bilge pump, or fish locator. OPTIMA Batteries. If you're looking for pure power, look no further. OPTIMA Batteries, made by Johnson Controls, deliver supreme performance and reliability. Our unique SPIRALCELL TECHNOLOGY® gives OPTIMA Batteries over 15 times more vibration resistance and increased cycle life compared to traditional batteries. Off-season battery maintenance will provide extended run time and lifetime for your marine battery. Deep Cycle Marine and Boat batteries work best when the charge is maintained in the battery – do not store the battery in a discharged state. Use a top quality Marine Battery Charger. While a deep-cycle battery can be used as a starting battery, the lower cranking current implies that an oversized battery may be required. A deep-cycle battery is designed to discharge between 45% and 75% of its capacity, depending on the manufacturer and the construction of the battery. Although these batteries can be cycled down to 20% charge, the best lifespan vs cost method is to keep the average cycle at about 45% discharge. A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity. In contrast, starter batteries (e.g. most automotive batteries) are designed to deliver short, high-current bursts for cranking the engine, thus frequently discharging only a small part of their capacity. Tips to extend the life of your Deep Cycle marine battery. 1  Off-season battery maintenance will provide extended run time and lifetime for your marine battery. 2  Deep Cycle Marine and Boat batteries work best when the charge is maintained in the battery – do not store the battery in a discharged state.
Yes, all are deep-cycle batteries that can meet all your marine power needs.
