The 2V1000Ah industrial lead-acid batteries has excellent service life for long-term standby operation. Under standard float charging standby conditions at 25℃, its design service life reaches 10-15 years, making it the preferred standby power supply for communication and power industries. In cyclic operation scenarios, the cycle life exceeds 2000 times with standardized charging and discharging. Temperature is the key factor affecting service life; high temperature accelerates plate sulfation and electrolyte loss, while low temperature reduces discharge efficiency. With monthly self-discharge rate ≤3%, it has low static loss and is not easy to fail after long-term idle storage. Standard temperature control and charge-discharge management can effectively extend its service life.
