    Three Fast Charging Ways

    With the LiTime 12V 20Ah starting battery, you can choose from three convenient charging options to suit your needs. Whether you use a LiFePO4 battery charger,  generator, or outboard alternator, you can fully charge your battery efficiently and reliably. We recommend 0.5C(10A) charging current, about 2 hours to charge fully. And only 40 minutes to fully charge if charged with a maximum continuous charge current of 1.5C (30A).Compared with lead-acid battery charging (usually charging current is 0.1C), the max. The charging current of the LiFePO4 battery can shorten the charging time by 15 times, so it can be charged with more power in a shorter period, which can satisfy the demand of going out in a hurry.

    FAQ

    Q: Can I use the battery to start the car engine?

    A:

    No. Please DO NOT use it as a starter battery for any type of vehicle, suchas cars, motorbikes, tractors, etc.

    For better using the battery, here are some safety precautions to notice:

    1. Do not use this battery as a starter battery for any type of vehicle, such as cars, motorcycles, trucks, etc.  

    2. This battery is not suitable for engines (such as outboard motors) that use a charging coil instead of an alternator.  

    3. When used in marine starting equipment (such as fuel outboard engines) or in environments with vibration, ensure the battery is securely mounted. However, it should not be used in areas with intense vibrations, such as tractors.  

    4. When using with outboard engines or in shaking environments, make sure to securely fasten the battery to prevent damage from movement.  

    5. Position the battery closer to the outboard motor, as different cable lengths may cause a certain amount of voltage loss, typically between 3% and 10%. If the voltage drop caused by the cable exceeds this range, the total cable length should be reduced.

    6. The 12V 20Ah marine cranking battery supports an IP67 protection rating. To avoid potential issues, do not fully submerge it in bilge water. To prevent parts of the battery from being exposed to water, it is recommended to install the battery in a waterproof battery container and/or place it in an elevated position.

    Q: How to know whether the battery can be applied to start my fuel outboard motor?

    A:

    Please ensure that your fuel outboard motor meets the following conditions when selecting a battery:

    1. Verify that the CCA (Cold Cranking Amps) required by your fuel outboard motor is less than the battery's CCA value of 650A.
    2. If your fuel outboard motor has an alternator, please ensure that the alternator's output current is less than the battery's maximum supported charging current of 80A.

    Q: What should I do when I receive the battery?

    A:

    When you receive your battery, please note that it may have a low State of Charge (SOC) due to transportation and storage. For optimal performance, we recommend charging the battery immediately to avoid over-discharge.  

    Fully charge the battery with battery charger for LiFePO4 lithium  before first use. Battery voltage lower than 11.5V will not be able to start motors.

    The duration of a single start cannot exceed 3 seconds.When the primary ignition fails, wait for 15 seconds beforerestarting.If the motor still cannot be started after three ignitions, checkfor other causes and wait 5 minutes before igniting again.

    Q: Can I connect the LiTime 12V 20Ah marine cranking battery in series or parallel?

    A:

    No. This battery doesn't support series or parallel connection.
