12.8V 7.5Ah Motorcycle Starting Battery Solution

Writer: TOPAKRelease time: 2023-12-19Page View: 0

The motorcycle starter battery is an important component of the motorcycle, and its function is to provide sufficient current when starting the engine, so that the engine can start normally. Motorcycle starting batteries are usually composed of lead-acid batteries or lithium-ion batteries. Lead acid batteries are a relatively traditional type of battery, with large weight, small capacity, and low temperature difference; Lithium ion batteries have higher energy density and lighter weight. Generally speaking, if a motorcycle needs to start frequently or be used in cold environments, it is necessary to choose a larger capacity and longer lifespan starting lithium battery.

Electrical Characteristics & Test Condition

No	Item	Standard	Test condition
1	Normal capacity	≥7.5Ah	After Normal charge, discharge @0.2C current to the end of discharge voltage.
2	Internal Impedance	≤10mΩ	@50% SOC @1kHz AC internal resistance test Instrument.
3	Discharge temperature Characteristic	-20℃/25℃≥45%	Battery shall be charged according to standard charge, discharged at 0.5C to 10.0V. Battery shall be stored for 4 hours at the test temperature prior to discharging and then shall be discharged at the test temperature, The percentage shall be calculated using discharging capacity compared to the minimum capacity
		-10℃/25℃≥65%
		0℃/25℃≥70%
		25℃/25℃≥100%
		55℃/25℃≥95%
4	Discharge performance in normal temperature	Discharge capacity 0.2C ≥100%	When the battery is in the environment of 25 ℃± 2 ℃, after standard charging, rest for 10min, and then discharge to 10.0V with 0.2C, 1C, 2C. Calculate the ratio of discharge capacity to rated capacity at each multiple.
		Discharge capacity 1C ≥98%
		Discharge capacity 2C≥95%
5	Cycle life@DOD100%	≥2000 cycles	After Normal charge，discharge @0.5C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.
