Technical FAQs 4

How do I choose a lead-acid battery?

Understanding core technical parameters is critical when selecting lead-acid batteries (especially gel or lead-carbon types). This guide breaks down rated voltage, max charge/discharge currents, depth of discharge (DOD), cycle life, and power calculations to help you optimize battery lifespan and system design. 1. Rated Voltage

How long does a deep cycle lead-acid battery last?

Deep-cycle lead-acid batteries appropriate for energy storage applications are designed to withstand repeated discharges to 20 % and have cycle lifetimes of ∼2000, which corresponds to about five years. Battery capacity is reported in amp-hours (Ah) at a given discharge rate.

What is the capacity of a lead-acid battery?

Ordinary lead-acid (0.1C): Min. capacity = 1000Ah Lead-carbon (0.25C): Min. capacity = 400Ah Discharging Current (Load-dependent): *10kW load + 48V battery* → Max discharge current = 200A Lead-carbon battery(30I₁₀): Min. capacity = >80Ah Gel battery (3I₁₀): Min. capacity = 800Ah 3. Depth of Discharge (DOD) & Cycle Life: Shallow Cycle: 10-30% DOD

How long does a lead-carbon battery last?

Cycle life numbers (4,880 / 3,760 / 998) Power calculations (3kWh theoretical → 2.1kWh usable) Lead-carbon batteries offer superior performance in high-current scenarios (0.25C charging, 30I₁₀ discharge) and extended cycle life at partial DOD.
