Announcement of soil testing results of Shandong Ruiyu Storage Battery Co., Ltd. in 2020

Calculation method:
Add up the total power of the device
For example, the total power of the washing machine = the power of the brush motor + the power of the suction motor + the power of the driving motor
The total power of the device ÷ the voltage of the device = the number of currents during discharge
The number of current during discharge × the working hours of the equipment = the battery capacity that meets the requirements
Remarks: Due to the volume of the battery tank of the equipment, the battery may not meet your requirements (because the volume of the large-capacity battery is also large), so you can only choose a large-capacity battery to meet your needs. 
How to avoid misleading selection of batteries and chargers
Choose the right channel:
Consult with companies engaged in the battery industry
As we all know, car manufacturers do not produce tires and batteries, and refrigerator manufacturers do not produce electricity. Cleaning equipment manufacturers and sellers also do not produce batteries, and they do not have expertise in batteries. As far as we know, some sellers of cleaning equipment provide users with start-up batteries or backup power batteries (probably for reasons that are not understood), and the use time of the batteries is greatly shortened or even invalid after 3 months of use. In addition, some sellers do not guarantee the battery. 
Remarks: Sellers of cleaning equipment can only sell machines without batteries and chargers, and do not mistakenly think that using their machines must use their batteries and chargers (batteries and chargers and cleaning equipment are completely two industries) . 
Consult with companies engaged in power batteries
As far as we know, some users go to the auto parts market to buy starter batteries. Sellers who are engaged in car start-up batteries generally do not know much about power batteries, and even if they understand them, they are out of stock. Generally, they need to order, and then they will transfer the goods to companies specializing in power batteries. In addition, power battery companies are equipped with intelligent chargers to ensure the service life of the battery. 
Note when purchasing:
price: 
If the price is too low, it can generally be a starter battery or an ordinary charger. 
Weight of battery:
The capacity of the battery depends on the area of ​​the internal active material, and the main component of the lead-acid battery is lead. The specific gravity of lead is 11.36g/cubic centimeter, so the larger the volume, the greater the capacity. In addition, if the nominal rated capacity of different manufacturers is the same, the weight is compared. Under normal circumstances, the heavier the weight, the more accurate the data. 
What is the standard for the rated capacity of the battery:
Because there are several different discharge rates in the world (that is, the discharge rate of the battery is expressed by the discharge time or the number of hours required to discharge the rated capacity with a certain discharge current), the common ones are 20-hour rate and 10-hour rate. , 5 hour rate. Generally, the nominal capacity of the 20-hour rate is only 85% of the 5-hour rate. Therefore, using different standards will result in completely different usage times. 
Distinguish the type of charger:
Ask if the charger is dedicated to the power battery
Ask if the charger is power frequency or high frequency
Ask if the charger has a multi-stage charging function
Inform you of the working voltage and capacity of the battery
Never use an open-type battery charger to charge a valve-regulated lean-liquid battery (so-called maintenance-free battery). 
The two charging curves are different, and the termination voltage is different. If an open battery charger is used to charge a valve-regulated lean battery (so-called maintenance-free battery), the valve-regulated lean battery (so-called maintenance-free battery) will be overcharged; otherwise, it will be undercharged.
