Rated voltage: voltage at which the battery works normally.
Rated capacity: For example, 28Ah (20hr, cell, 25 ° C) means that at 25 ° C, 20 hours of discharge (that is, 20 hours of discharge) reduces the voltage of a single battery to the released capacity, which is converted to 1 hour discharge ampere value. Dimensions: Length, width, height, total height.
Internal resistance: for example: Ω (25℃, fully charged)
CCA: cold start current value: under the conditions of ℃ and ℃, the minimum current that the battery can supply when the terminal voltage drops within 30s of a fully charged 12V battery.
Reserve capacity (25 ° C) : fully charged 12V battery, under the condition of 25±2 ° C, at 25A constant discharge until the battery terminal voltage drops to ± discharge time.
Ambient temperature: battery operating temperature, some subdivided charging temperature and discharge temperature.
DODxx% : The battery uses xx% of its power. For example, "DOD80%, 700 times" means that the battery uses 80% of its power each time and can be recycled 700 times.
Maximum charging current: e.g. It refers to the maximum charging current multiplied by the battery capacity value based on the 20-hour discharge standard.
Maximum discharge current: refers to the maximum discharge current when the battery capacity value is multiplied by the 20-hour discharge standard.
Cyclic charging voltage: also known as floating charging voltage, refers to the battery pack and the power line connected in parallel to the load circuit, the power line is only slightly higher than the open voltage of the battery pack, a small amount of current provided by the power line to compensate for the loss of the local role of the battery pack.
So that it can often be kept in a satisfied state of charge without overcharging. Electrode L or R: there are positive and negative batteries. Method of differentiation:
1, on the outer packaging or battery, the reverse pole battery is generally marked with the word "L". Positive batteries are generally not marked.
2, facing the battery pole near their side, the positive battery '+' pole on the left side of the battery, and vice versa on the right side.
Specific energy: Volume energy density: wh/L as a unit, reflecting the unit volume of the battery can store energy size. Weight energy density: wh/kg as a unit, reflecting the unit weight of the battery can store energy size. Specific power: In kw/kg, it reflects the power that the battery can output per unit weight.
