Frequently Ask Questions
Using a compatible smart charger, connect the positive (red) clip to the positive terminal and the negative (black) clip to the negative terminal, or use the charger provided with the lithium battery.
a lead-acid or lithium battery designed to provide steady, long-term power and endure repeated, deep discharges (typically 80% or more) before requiring a recharge
Lithium (LiFePO4) batteries offer the longest lifespan at 10–15+ years (2,000–5,000+ cycles)
While you can technically use a deep cycle battery in a car in an emergency, it is generally not recommended for daily use because they lack the high cold cranking amps (CCA) needed for engine startup and may be damaged by high-current charging
Deep cycle battery disadvantages include higher initial cost, poor performance for high-burst needs (like starting engines), shorter lifespan than lithium alternatives (especially lead-acid types), weight, potential maintenance (water levels for flooded), slower recharge times, and sensitivity to deep discharge which damages them
Deep-cycle batteries are designed for frequent charging and discharging. These batteries store electrical energy through chemical reactions and are therefore crucial for renewable energy systems.
Know the capacity of your deep cycle battery and do not discharge it beyond its recommended limit. Over-discharging can damage the battery and reduce its lifespan. Use loads that are within the capacity of the battery. Avoid connecting high-power devices that can draw too much current and damage the battery.
A 12-volt deep cycle battery typically weighs between 20 and 35 lbs for lithium (LiFePO4) and 40 to 100+ lbs for lead-acid/AGM models, depending on capacity. A standard 100Ah lead-acid battery usually weighs 60-80 lbs, while a 100Ah lithium battery weighs roughly 20-30 lbs.
While traditional lead-acid options offer deep-cycle versions, they are limited by a 50% usable capacity to avoid permanent damage. Our advanced chemical architecture allows for 100% Depth of Discharge (DoD), providing twice the energy in a lighter, more durable package without the risk of voltage drop
Deep cycle batteries are designed to provide a steady, long-term power supply and can be repeatedly discharged up to 80% of their capacity, unlike car batteries. They are primarily used in solar/renewable energy systems, RVs/campers, marine vessels (trolling motors), golf carts, forklifts, and electric mobility scooters.
