What is a safe Max discharge current for a tubular lead acid battery?

When they say "maximum current of 1 A", that's just a compromise value that they picked. They could have picked 0.5 A and increased the expected life, or 2 A and decreased the expected life. So, when you ask "What is a safe max. discharge current for a tubular lead acid battery?", there is no specific answer.

Does a lead acid battery have a maximum current rating?

Unlike LiPo batteries with have a maximum current rating, the lead acid battery only stated the "initial current", which is used for charging. The label stated not to short the battery. Hence, may I know what/how to find out the safe current to draw? How will the battery fail if I draw too much current (explode/lifespan decreased/?)? Thanks

How long does a deep-cycle lead acid battery last?

A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.

What is a lead acid battery?

Lead acid batteries are fantastic at providing a lot of power for a short period of time. In the automotive world, this is referred to as Cold Cranking Amps. From GNB Systems FAQ page (found via a Google search):

Can a lead acid battery stall a motor?

The motor can draw quite a lot of current when stalling and I am worried of overdischarging the lead acid battery. Unlike LiPo batteries with have a maximum current rating, the lead acid battery only stated the "initial current", which is used for charging. The label stated not to short the battery.

What is a safe max. discharge current for a tubular lead-acid battery?

C20 gives us the recommended current to obtain the advertised cycle life (900 cycles at 80% DoD) using the below equation: My battery bank is 450 Ah divided by 20 hours; 450/20 = 22.5 A. If I need to discharge for 15 to 20 minutes (less than 20 hours), can I use more than 22.5 A and still maintain the same cycle life?
