Lead-acid Batteries With Voltage Stability Characteristics
- Aug 22, 2017 -

Lead-acid battery It mainly refers to the lead and its oxide, the electrolyte is a sulfuric acid solution of a battery. Discharge state, the main component of the cathode is lead dioxide, Standard Lead Acid Battery the main component of the negative lead; charge state, the main components of the positive and negative are lead sulfate. Divided into exhausted batteries and maintenance-free lead-acid batteries.

Lead-acid batteries mainly by the tube positive plate, negative plate, electrolyte, partitions, battery slot, battery cover, pole, injection liquid cover and other components. Generally according to their characteristics can be divided into three categories, ordinary battery, Standard Lead Acid Battery which is mainly a voltage stability, cheap, Standard Lead Acid Battery long life and other characteristics.

Because the lead-acid batteries generally have a safe seal, no free acid, deflated system, easy maintenance, long life, stable quality, high reliability, so it is widely used in tractors, tricycles, cars, uninterruptible power supply, Motor power and other occasions and areas.

Lead-acid batteries, also known as lead-acid batteries, is a kind of battery, the electrode is mainly made of lead and its oxide, the electrolyte is a sulfuric acid solution of a battery. In the charged state, Standard Lead Acid Battery the main component of the cathode is lead dioxide, and the main component of the negative electrode is lead. In the discharge state, the main components of the positive and negative are lead sulfate. Generally divided into open-type battery and valve-controlled battery two. The former need regular maintenance of the acid, Standard Lead Acid Battery the latter for the maintenance-free battery. According to the battery model can be divided into small dense, dense and dense. The main advantage is voltage stability, cheap and so on. Lead-acid battery (LAB), refers to the positive and negative active substances are lead and lead dioxide, sulfuric acid aqueous solution as the electrolyte secondary battery. Rich liquid and poor liquid two categories, poor liquid is widely used in the valve-regulated closed lead-acid batteries, in fact, it is not completely closed. Mainly used in transportation, communications, Standard Lead Acid Battery backup power and other fields. With low prices, high reliability, easy maintenance and so on. As the lead to the human body harmful, sulfuric acid pollution of the environment, corrosion equipment, so the application area is limited. Although there is a tendency to be replaced by nickel-metal hydride, lithium-ion batteries, etc., Standard Lead Acid Battery most of the secondary battery market will be occupied for a long time due to price, safety, reliability and other reasons.

What is the lead-acid battery capacity labeling method?

Should be C2, whichever is 0.5C2 current discharge, when the voltage reaches the battery discharge termination voltage when the discharge time and current product should be equal to or close to the rated capacity value. For example: a 12V, 12Ah battery to 5A current discharge, Standard Lead Acid Battery discharge termination voltage of 10.5V, the time can not be less than 140min; Similarly, a 12V, 10Ah battery to 5A current discharge to the voltage to reach the termination voltage of 10.5V, Time can not be less than 120min. The error is 0.1Ah

In fact the industry standard: 10Ah battery to 5A current discharge to the termination voltage time shall not be less than 120min. Enterprise products actually reached 130 ~ 137min.

What is the battery overcharge capability?

Industry standards, lead-acid batteries to 1.2A continuous charge 48h, Standard Lead Acid Battery the actual capacity of not less than 95% of rated capacity.

What is the battery's overdischarge capability?

Industry standards, lead-acid batteries began to discharge current of 12A ± 1.2A, in order to determine the continuous discharge mode 2.0h, the actual capacity of not less than 75%

What is the low temperature preservation feature of the battery?

Industry standards, lead-acid batteries in the -10 ℃ ± 0.1 ℃ under the conditions of environmental storage 10h, Standard Lead Acid Battery the actual capacity can not be less than 70%.

How to evaluate the life of lead-acid batteries?

With a capacity of 75% of the depth of discharge, Standard Lead Acid Battery life should not be less than 350 times.
