What does C5A mean and how do I interpret this datasheet?
1C5A is a standard measurement of the battery capacity, in this case 800mAh. The "5" is for 5 hour ratings where applicable. So, the rating of 800mAh is actually at 0.2C5A. meaning it will provide 20% of the rated capacity (160mA) for 5 hours before the voltage drops to the final terminal voltage of 2.75V (according to datasheet) Farther down, it states 1C5A

What is a battery discharge limit?
This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity. Maximum 30-sec Discharge Pulse Current This is the maximum current at which the battery can be discharged for pulses of up to 30 seconds.
How long can a battery be discharged?
Maximum 30-sec Discharge Pulse Current This is the maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
What is a maximum discharge current?
Maximum Continuous Discharge Current This is the maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity. Maximum 30-sec Discharge Pulse Current
What is the electrical symbol for a battery cell?
This electrical symbol for a battery cell is used no matter what the battery chemistry is. The Open Circuit Voltage (OCV) is a fundamental parameter of the cell. The OCV of a battery cell is the potential difference between the positive and negative terminals when no current flows and the cell is at rest.
How do you write a discharge current?
The discharge current may alternatively be expressed as a multiple of the rated discharge current. For example, if the batt ery is specified at the 10 hour rate, I 10 = C/10 (Ah/h) and is the current which would discharge the battery in 10 hours. Then, if C = 40 Ah, I 10 = 40/10 = 4 A and a current of 10 A can be written as 2.5 I 10.
How does a battery discharge a charge?
A battery delivers direct current (DC) and must be recharged with direct current in the opposite direction of the discharge. In a battery, one discharge plus one recharge equals one cycle. When a battery is delivering current, it is said to be discharging. In a lead-acid battery, the electrolyte is sulphuric acid diluted with water.
