Applicability of power tool lithium batteries in UPS power supply When considering using power tool lithium batteries on UPS power supplies, it is important to note that the charging voltage range of lead-acid batteries used in UPS is usually between 14.5-15V and cannot be adjusted. Directly matched power tool TLB12 series batteries may not charge properly.
This is because the electric tool battery is a ternary battery, usually three 3.7V batteries connected in series, and the maximum charging voltage does not exceed 12.85V. If you use UPS to charge directly, it will cause excessive voltage protection and prevent normal charging.Therefore, when determining whether a power tool lithium battery can be used in a UPS power supply, you first need to clarify the voltage of the power tool battery and check whether the UPS supports multi-mode charging function or whether the charging parameters can be adjusted. In addition, the charging voltage range of different types of batteries is also different. For example, the voltage of 3-string ternary lithium batteries for power tools is 12.3-12.6V, the voltage of 4-strings of energy storage lithium iron phosphate is 14.4-14.6V, and the voltage of lead-acid batteries is 14.4-14.6V. The battery charging voltage is 14.5-15V.
Advantages and Disadvantages of GEL Batteries Adding glue to batteries has its advantages and disadvantages. Among the advantages include preventing water loss during charging and discharging, which is beneficial to extending battery life. However, the disadvantage is that it blocks the rapid transfer of electric ions and increases internal resistance, which is not conducive to instantaneous large current discharge.
Therefore, it is not recommended to add glue to starting batteries, as this is not conducive to high current output during instantaneous starting. However, for energy storage, EVF, electric vehicle batteries and other occasions that require small current discharge, adding glue is relatively necessary.
