Marine Cranking Battery

Yes, the Redodo marine cranking batteries can be operated at a temperature of -20°C to 60°C (-4°F to 140°F). These marine starting batteries can be charged between 32°F (0°C) and 122°F (50°C), discharged between -4°F (-20°C) and 140°F (60°C), and resume charging above 41°F (5°C). For best results, avoid exposing your marine cranking battery to prolonged periods of extreme temperatures, as this can reduce overall lifespan.

Redodo marine cranking batteries come equipped with a high CCA and MCA rating, providing reliable power for starting engines in demanding marine environments. These batteries are built with an advanced Battery Management System (BMS), offering protection from overcharging, over-discharging, overcurrent, short circuits, overheating, and low temperature. Additionally, the IP67 rating makes these marine starting batteries highly resistant to dust and water. The use of EV-grade cells enhances longevity, making these batteries a durable choice for both recreational and commercial marine applications.

When selecting a marine cranking battery, ensure the CCA value that your fuel outboard motor required is lower than the battery’s CCA value, which is the battery's ability to start the engine in low temperatures. Also, ensure the alternator's output current is lower than the battery's maximum supported charging current, if your fuel outboard motor has an alternator. Larger engines or boats with multiple electrical systems require marine starting batteries with higher CCA ratings to ensure reliable starts.

CCA (Cold Cranking Amps) and MCA (Marine Cranking Amps) are both measurements of a battery's ability to start an engine, but under different temperature conditions. CCA measures starting performance at 0°F (-18°C), while MCA measures the battery’s cranking ability at 32°F (0°C). Since boat cranking batteries operate in warmer temperatures, MCA ratings are generally higher than CCA. However, CCA is a key factor when selecting a marine cranking battery for your boat.

Redodo boat cranking batteries are designed for a lifespan of 5 to 10 years, depending on usage patterns and proper maintenance. For example, as starter batteries, the 12V marine cranking battery can provide 5000+ cranking times. And as energy storage batteries, the 12V dual purpose battery can offer over 4000 cycles—these boat cranking batteries are built for long-term reliability. Regular inspection and storage in favorable conditions can help prolong the lifespan of your marine starting battery.

Yes, some Redodo boat cranking batteries, such as the 12V 140Ah dual purpose model, are capable of both cranking and deep-cycle functions. This means the battery provides sufficient CCA to start an engine and can also power electronics such as trolling motors and navigation systems. This versatility makes these batteries ideal for boaters who need both high cranking power and steady energy for prolonged use of onboard systems.

Redodo marine starting battery features a comprehensive Battery Management System (BMS) that offers 6 different types of protection. These safeguards include protection against overcharging, over-discharging, short circuits, overcurrent, low temperature and overheating, ensuring the safe operation of the battery. The BMS enhances the overall efficiency of the battery, preventing potential damage from unsafe operating conditions. What’s more, the marine starting batteries are equipped with low-temp cut-off protection, making these batteries a reliable and safe choice for any marine vessel in cold conditions.

Yes, Redodo marine starting batteries come with an IP67 rating. This feature makes these batteries suitable for use in marine environments where exposure to water is common. However, it’s still recommended to install your battery in a protected area to prevent long-term exposure to water or salt.

The weight of Redodo boat starting battery varies by model. A smaller capacity battery - Redodo 12V 20Ah cranking battery only weighs around 9.68 lbs (4.39 kg), while larger capacity versions of 140Ah dual purpose battery weigh as much as 36.67 lbs (16.53 kg). The relatively lightweight design compared to traditional lead-acid batteries makes installation easier and more convenient for boat owners. The weight of the battery is also an important factor to consider if you have limited space or need to move the battery frequently.

The ability to connect multiple Redodo marine cranking batteries depends on the specific model. For the 20Ah cranking battery, it can support 1P1S. However, for the 140Ah dual-purpose battery, if you use it only for energy storage, it can support up to 4P4S; if you use it for starter & deep cycle purposes, it can support up to 4P1S.  For optimal performance and safety, ensure that the batteries have the same type, BMS, and capacity, and are purchased around the same time (within one month).
