In other words the faster you drain a lead acid battery the less total current you have to work with over the charge life of the battery. In my example above, the 20 amp hour battery above can produce 1 amp for 20
However I am a bit confused about amp hour ratings. As I understand it a lead acid battery should only be discharged to about 50%, but a LiFePO4 can be discharged much deeper, perhaps as low as 10% or even lower. Unless the lead acid battery amp hour rating is for "usable" amp hours and not the true total in the battery, in which case both
Written by Ryan Gilmore Updated: 20 December 2024. If your car battery is playing up, a quick fix is a quality battery charger, but the time may have come for a new battery.Without a battery, your car is, quite literally, a non-starter. Turn the ignition key or press the start button, and the car should if the battery is charged, fire into life.
To ensure that ratings are given in a realistic way, lead-acid batteries have a few parameters on how they get that “AH” rating. In order to get an AH rating, the battery that
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

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.
For example, this means that a lead-acid battery rated for 200 Ah (for a 10-hour rate) will deliver 20 amperes of current for 10 hours under standard temperature conditions (25C or 77F). Alternatively, a discharge rate may be specified by its charge rate or C-rate, which is expressed as a multiple of the rated capacity of the cell or battery.
The internal characteristics of lead-acid batteries exhibit a relatively higher self-discharge rate compared with some other battery chemistries. For instance, the self-discharge rate of lead–acid batteries is affected by factors such as temperature and battery age. High temperatures accelerate the self-discharge process.
