Frequently Asked Questions
How long does a 12V 100Ah lithium battery last?
Based on manufacturer specifications, a 12V 100Ah lithium battery typically lasts between 2000 and 5000 cycles depending on the depth of discharge and brand. This is significantly longer than lead-acid batteries, which usually last 300 to 500 cycles. In practical terms, with regular use, the battery can last over 10 years.
Can I use a standard lead-acid charger for a lithium battery?
We researched charging requirements and found that while some modern lithium batteries have built-in BMS that can handle lead-acid charging profiles, it is not recommended for optimal longevity. It is best to use a charger specifically designed for LiFePO4 batteries to ensure the correct voltage thresholds and absorption times are met.
Do I need a battery box for a lithium trolling motor battery?
Our evaluation indicates that while lithium batteries are sealed and do not vent gas like lead-acid batteries, a battery box is still highly recommended. It provides physical protection against impacts and water exposure, which is crucial in the marine environment. Many manufacturers also require a battery box to validate the warranty.
Why is the CCA rating not listed for lithium batteries?
In our research, we found that CCA (Cold Cranking Amps) is a metric specific to lead-acid starting batteries. Lithium iron phosphate (LiFePO4) batteries are designed for deep cycle applications, not engine starting. Therefore, manufacturers list continuous discharge amps (such as 100A or 200A) instead of CCA.
Is it safe to mount a lithium battery on its side?
Based on the evaluation of LiFePO4 technology, these batteries are completely sealed and can be mounted in any orientation, including on their sides. This offers flexibility in tight battery compartments. However, it is important to ensure the terminals are protected and the battery is securely strapped down regardless of orientation.
