| How to Install UPS Batteries
The battery connection method shown in this article is an example, and there is no doubt that the on-site composition varies from site to site. |
| When connecting the batteries, all the batteries in series must be completely identical.
Series connection In series connection, some batteries are connected by connecting the positive pole to the negative pole. The positive battery of the first battery is connected to the negative battery of the second battery, the second positive battery to the third negative battery, etc. The total battery voltage is equal to the total voltage of the individual batteries and must be connected in such a way as to be proportional to the DC voltage required by the UPS. Using this method in connecting batteries, the battery service capacity remains constant and is equal to the initial value of each battery. For example: If 12 12V and 10Ah batteries are connected in series, the resulting battery will have 144V and 10Ah capacity.
Parallel connection The parallel connection is a combination of two or more series connections and should have the same number of batteries in each row. Batteries are paralleled for two important reasons. The first reason is the increased service capacity of the battery (Ah). The second reason is to increase the overall battery flexibility so that one battery in the set does not make the other batteries unusable for the UPS. Also, the negative connector of the first battery series is connected to the negative connector of the second series and the negative connector of the second …The total battery voltage is equal to the voltage of each row of batteries, and its total capacity is equal to the sum of the total capacity of each battery. The connection will have 144V and 30Ah capacity.
It is not common to parallelize more than 6 rows of battery series.
