The most common type of maintenance during battery use is balanced charging. The essence of balanced charging is an "overcharge" of the battery. Balanced charging is still one of the ways to address battery inconsistency. Since the process is used in a series battery loop, there will be a difference between the battery and the battery, a difference in capacity, and a difference in voltage (terminal voltage). In order to prevent the battery from widening and develop into a "backward battery" (faulty battery), it is necessary to perform balanced charging on a regular basis.
1 Balanced charging should also be performed in the following special cases.
a. The battery pack supplies power to the load for more than 15 minutes, and requires balanced charging;
b. After the battery is deeply discharged, it is found that the battery capacity is insufficient and needs to be charged evenly.
2 equalization charging method depends on the situation
a, I hope to improve the battery characteristics by equalizing the charging, this situation can be selected by the regular full charge method, according to the use of the provisions: all charged once every six months. This can be automatically set on the charging device, and then automatically equalizes the charging, and after a few hours of charging, it is converted into a floating charging mode, so that the "backward battery" capacity can be complemented.
b. It is hoped that the capacity to be replenished after the discharge is restored by the equalization charge can be carried out according to the full charging method or by the incremental voltage charging method (first floating charge and then boosting).
How long (t) is required for equalization charging, depending on factors such as the depth of the battery discharge, the size of the selected current limit, the temperature at which the battery is located, and the charging device.
Current-limiting charge values ​​are set differently, usually 0.15-0.25CI. (A). Some countries have also set 0.1C10(A) to 0.3 C10(A), and the charging time can be estimated based on the current limit setting.
The time required for balanced charging should not be too long, so that the surplus gas in the battery is too much, which affects the oxygen recombination efficiency; and the corrosion rate of the positive grid is accelerated to damage the battery, and the charging voltage of the balanced charging is higher than the floating charging voltage, and the floating charging is performed. The internal oxygen compounding efficiency of the battery is the highest. The voltage of the balanced charging is already a high-voltage charging. If the voltage is increased by 10OmV, the floating charging current will increase by 10 times, which causes damage to the battery.
In order to reduce the maintenance workload and reduce the number of balanced charging, an effective method is to install a battery voltage balancer. This device enables uniform charging of each cell in a series circuit. According to the health of each single battery, it is allocated to the battery float current flow, for those who have sufficient battery power, less floating charge current, for those who have insufficient battery power, a little more floating charge flow. In this way, each single cell in the series circuit that has been working for a long time does not cause "undercharge" and "overcharge", which greatly improves the uniformity of each cell in the series circuit, and improves the battery pack. The performance of each battery in the battery pack is always in optimal working condition.

Drop-in kitchen sinks, also called self-rimming sinks, overmount sinks, or top-mount sinks, are sink basins that install and sit on top of your kitchen counter. There is a visible rim or lip on the perimeter of the basin that rests just over the cut-out for the sink. Drop-in sinks are supported by this lip and a series of hidden clips that attach to the underside of the countertop.
The Advantages of Drop-In Sinks
Drop-in sinks have some clear advantages over other styles, especially in the kitchen.
Cost
They`re generally cheaper to buy and easier to install than undermount sinks. In fact, even weekend warriors and DIY newbies should have no problem installing a basic overmount sink. If cost is a consideration in your kitchen, an overmount sink with a do-it-yourself install is a great way to stay within budget.
Cleaning
While cleaning may not be your foremost concern when choosing a kitchen sink, it should be considered. After all, you`ll have to care for and maintain your sink regularly. The basin of an overmount sink is easier to clean than the basin of an Undermount Sink.
Protection
If you`ve got soft countertops, drop-in sinks can help protect the edges of the sink cutout.
- Marble and some specialty counter finishes benefit from the added protection provided by the lip of a drop-in kitchen sink basin. It prevents the build up of water on the surface edges of the stone through repeated exposure of use.
- If you have laminate countertops, drop-in sinks are the only option: the particle board below the laminate surface isn`t strong enough to support undermount sinks but plays well with self-rimming basin types.
