6 FAQs about [Lead-acid battery only has 2 5 amps]

How much current does a lead-acid battery have?

A lot depends on the design of the battery. For example: coin cells with 500mAh capacity may have only 3mA max current. Another (opposite) example: automotive starter battery with 40Ah capacity may have 500A max current. Lead-acid batteries are interesting in this respect, because there are two distinct types.

How long does a lead acid battery last?

Even though batteries have been around for a while, it is still not clear as to why a lead acid battery connected to a 5 amp appliance last 20 hours, but when connected to a 10 amp appliance, the time drops by more than half, to around 7.5 hours.

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.

What is a lead-acid battery?

Lead-acid batteries are interesting in this respect, because there are two distinct types. Starter lead-acid batteries are designed specifically to deliver high peak current for a short period of time. Deep discharge, however, dramatically shortens the life of a starter battery. So, it's not suited for routine operation at high depths of discharge.

How many kWh can a lead battery charge?

As a rule of thumb: a 25kg lead can charge 1kWh. So a battery of i.e. 8kg can deliver around 280Wh (guessing a bit. 0.5kg housing, 0.5kg acid) this is almost independent of what type lead battery it is since its based on the amount of lead used.

How many Ahr is a 10 amp battery?

10 amp constant current for 20 hours (10x20) = 200 AHR at 20 hour rate. 8 amp constant current for 3 hours (8x3) = 24 AHR at 3 hour rate. 30 amp constant current for 1 hours (300x1) = 30 AHR at 1 hour rate. In an application that requires 17amps for 3 hours, a 51 AHR battery (at 3 hour rate) would be needed.
