How to Determine Amp Hr Rate
For deep cycle batteries the standard rating is 20 hours. So, if a battery has a rating of 100AH @ 20Hr rate, then that battery was discharged over 20 hours with a 5 amp load. Starting batteries, on the other hand, are typically rated at 10Hr rate, because they are used faster, so the 20Hr rate is not as important.

6 FAQs about [Lead-acid battery rate and capacity]
What is the C-rate of a lead acid battery?
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.
What are the characteristics of lead-acid batteries?
Lead-acid batteries have a capacity that varies depending on discharge rate as well as temperature. Their capacity generally decreases with slow discharges while increasing with high rates. Moreover, lead-acid batteries suffer reduced capacity at extreme temperatures, especially during cold conditions. 3. Self-Discharge Rate
Should a lead acid battery be fused?
Personally, I always make sure that anything connected to a lead acid battery is properly fused. 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.
How deep should a lead acid battery be discharged?
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:
Do lead acid batteries have a good charge efficiency?
Lead acid batteries have reasonably good charge efficiency. Modern designs achieve around 85-95%. The amount of time and effort required to recharge the battery indicates this efficiency. This emphasizes the significance of repetitive charging as a component of applications.
When should a lead acid battery be charged?
It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating. A battery that is in a discharged state for a long time (many months) will probably never recover or ever be usable again even if it was new and/or hasn't been used much.
