6 FAQs about [7A lead-acid battery discharge current]
How long does a lead acid battery take to charge?
Last example, a lead acid battery with a C10 (or C/10) rated capacity of 3000 Ah should be charge or discharge in 10 hours with a current charge or discharge of 300 A. C-rate is an important data for a battery because for most of batteries the energy stored or available depends on the speed of the charge or discharge current.
Can a 12V lead-acid battery be charged at 0.5A?
This rule of thumb is problematic as a 12V lead-acid battery is actually 6x2V cells in series. If a 2V cell of a particular size was able to be charged at, say 0.5A, six of them in series (six times the capacity) should also be charged at 0.5A. Voltage and power will need to be higher but the current should be identical.
Can a SLA battery be charged at 7a?
Your SLA battery probably wont like being charged from 18V at 7A. If you use two batteries in parallel, then it will run for twice as long. You could use a pwm motor speed controller between your battery and fan. If you don’t require the fan to run full speed, then this might be a good solution for you. Pwm doesn’t waste the energy.
How many 7AH batteries should be in parallel?
Two 7Ah batteries in parallel should be ok. The pwm controller doesn't care how many batteries are in parallel. I am using a battery cutoff circuit to protect the battery from over charging which is connected on positive wire between power supply and XL4015.
How long does a battery last at 8A?
Even at 8A, the battery will be flat after half an hour. And be aware that lead-acid batteries don't like being left flat. Once run down, they should be recharged as soon as possible, or they may be permanently damaged. *1C is a current numerically equal to the amp-hour rating of a battery. So for an 8Ah battery, 1C is 8A.
How long does a battery take to charge and discharge?
Formula: C-rate in time (minutes) = (1 ÷ C-rate) × 60 The chemistry of battery will determine the battery charge and discharge rate. For example, normally lead-acid batteries are designed to be charged and discharged in 20 hours. On the other hand, lithium-ion batteries can be charged or discharged in 2 hours.
