How fast can you discharge a lead acid battery?
a lead acid battery will self-discharge at a rate of approximately 4% a week. A battery with a 125-amp hour rating would self-discharge at a rate of approximately five amps per week.
What is the maximum charge rate for a 12 volt lead acid battery?
Those batteries that are used in deep discharge cycling mode can be charged up to 2.45 volts/cell (14.7V for a 12V battery) to get the highest charge rate, as long as the voltage is dropped to the float voltage when the charge is complete.
What is the discharge rate of a 12V battery?
Ideally the manufacturer supplies the discharge rates on the battery datasheet. A quick point: You mention you have a 12 V 2.4 A SLA (sealed lead acid) battery, but batteries are rated in amp-hours not amperes. Therefore I suspect you have a 12 V 2.4 Ah battery.
What’s the Max discharge ( in ” C ” ) of a PB-acid battery?
Fig 1 shows the performance of a wide range of capacity batteries under a range of loads. The rated capacity is given at the 20 hour discharge rate. Fig 1 gives discharge curves up to about 3C rate (eg 30A for a 10Ah battery) but also shows that capacity decreases rapidly with increasing discharge rate.
When to top off a lead acid battery?
Lead acid cell should not become deeply discharged and should be charged as soon as possible after discharge. There is no harm in topping off after use even if not fully discharged. A little research and experience will allow voltage readings to help you determine the actual state of charge. Go Fly Something!!
Is it safe to use batteries at 1C?
In the past, batteries designed for rates >1C were usually marketed as “high current” batteries, because not all batteries were capable of sustaining such rates safely or without compromising its endurance. Nowadays, most batteries can safely be used at rates >1C, up to the rating specified by the manufacturer.
