AI Customer ServiceDischarge Rate: The discharge rate, often expressed in C-rates, indicates how quickly the battery is drained. A higher discharge rate can lead to a rapid voltage drop, risking
AI Customer ServiceA battery''s discharge rate is the amount of current it can deliver in a given time. The most common unit of measurement for discharge rate is the amp (A). For example, let''s say you have a 100-watt-hour lead-acid Battery
AI Customer ServiceHow long a battery lasts depends on the battery discharge rate. Understanding battery capacity can help you learn more about discharge rate. Peukert''s Law shows the

AI Customer ServiceWhat Is C-rate? The C-rate is a measure of the charge or discharge current of a battery relative to its capacity indicates how quickly a battery can be charged or discharged. Definition: A C-rate of 1C means that
AI Customer ServiceBattery capacity falls by about 1% per degree below about 20°C. However, high temperatures are not ideal for batteries either as these accelerate aging, self-discharge and electrolyte usage.

AI Customer ServiceSince that is no longer an issue (and never was an issue with lead acid batteries) there is not a need to fully discharge. By discharging a lead acid battery to below the manufacturer’s stated end of life discharge voltage you are allowing the polarity of some of the weaker cells to become reversed.
The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them. The most important lesson here is this:
It turns out that the usable capacity of a lead acid battery depends on the applied load. Therefore, the stated capacity is actually the capacity at a certain load that would deplete the battery in 20 hours. This is concept of the C-rate. 1C is the theoretical one hour discharge rate based on the capacity.
For instance, lead-acid batteries are notably sensitive to high discharge rates. Under such conditions, these batteries experience increased internal resistance, which can result in: Increased Heat Generation: High discharge rates elevate the internal temperature of the battery.
Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating.
All batteries experience some amount of self-discharge, yes. But, the rate of discharge for lead acid batteries depends on a few key factors. Temperature: The warmer the environment while a battery is in storage, the faster the rate of self-discharge.
