Charge characteristic:

Four-stage intelligent charging curve(small current activation→Large current constant current→Fixed pressure flow→ floating charge) is used in the charging process. The battery is recharged by small current at first. It can help to fully activate the rechargeable battery and improve the ability to accept large current charging charge in the second stage.The intermittent pulse current will be inserted which will activat original vulcanized plates and effectively reduce the battery plate vulcanizing phenomenon.Compared with the traditional three-stage charging, this way is more reasonable and effectively improve the battery usage. Embedded intelligent MCU control technology is integrated with the ways which is to identify battery power such as charging voltage rise rate(dv/dt), maximum charge voltage(Vmax), maximum charge time(Hmax) and so on. It can ensure battery not be over charged, under charged to achieve better charging effect.
