1, when the floating charge, please use the charging voltage 2.275V / single cell (setpoint at 20 ℃), were constant voltage charging or 0.002CA less current constant current charging. Temperature at 0? C or below 40? C over time,? It is necessary to amend the charging voltage to 20? C as the starting point for change once every, single-cell voltage change -3mv. 2, when the charging cycle, the charging voltage to 2.40-2.50V / single cell (setpoint at 20 ℃), were given the voltage charging. At a temperature above 5? C or less, or when charging 35 ℃ to 20 ℃ as a starting point, the charge voltage adjustment for each degree change -4mv / single cell. The initial charging current control 0.25CA less. Set the amount of charge-discharge capacity of 100-120%, but the ambient temperature is 5? C or less? Make 120-130%. [Lower temperature (5? C or less) the charging end time is longer, the higher the temperature (35? C or more) more prone to overcharging, so in particular when the cycle is used in the 5? C ~ 30? C in the charging better]? To prevent overcharging try to install the charging timer, or automatically converted into trickle charge mode. When charging the battery temperature should be controlled at -15? C ~ + 50? C in the range. ?? Second, on the battery discharge when the discharge temperature control at -15 ℃ -? + In the range of 50 ℃. ? Please continuous discharge current control 3CA following (H control 6CA below). ? Current discharge voltage varies depending on the size, roughly as follows. Note discharge, the voltage must not fall below the following voltage. ? Please charge quickly after discharge. Please also charged immediately after such careless over-discharge. Discharge current? Discharge termination voltage? 0.2CA under? 1.75CA / single cell? 0.2CA above? 0.5CA under? 1.70CA / single cell? 0.5CA above? 1.0CA under? 1.55CA / single cell? 1.0CA above? 1.30CA / single cell? Third, installation considerations? 1, not sticky or stickers class of objects to suppress the cover, because the cover underneath the exhaust valve, the gas generated within the battery will not be able to escape. ? Number 2 ,? parallel - float charging, plug-in terminal of the battery can be associated with up to three columns, bolt-type terminal is not particularly limited, but the increase in the number of small parallel reliability. In addition, when wired in parallel, it is necessary to consider making the connection between the conductor and the contact resistance equivalent to the columns, each column to make the charge and discharge the battery to maintain a balanced, do not over three practical use. When? 3, while using different capacity, different old and new batteries from different manufacturers, due to the different values ??of its properties has the potential to damage the battery and the machine, so please avoid using. ? Fourth, regarding custody? 1 Please note that during storage temperature should not exceed the range of -20 ℃ ~ + 50 ℃? 2, the battery must be kept in custody under NP batteries fully charged state. Because in transit or during storage due to self-discharge will lose some capacity, please add electricity use. ? 3, the long-term storage, to compensate for self-discharge during storage, please add power, add power method as follows:? Keeping the temperature of each issue of supplementary electric power storage temperature interval supplementary charge supplementary legislation (for example) 25??? ?? C the following six months time ?? nbsp; to 0.25CA, 2.275V / (single cell), constant current and constant voltage charging 2 to 3 days ?? nbsp; to 0.25CA, 2.4 / (single cell), constant current constant voltage charging 10 to 16 hours ?? nbsp; to 0.1CA constant current charging 3 ~ 5 hours 30 C following four months following the first three months 35 C 40 C following a two month????????? once? in more than 40? C during storage under conditions have a bad impact on battery life, avoid! ?
