The lead-acid battery was first introduced in 1859, and was and is now considered the first rechargeable battery. Lead-acid batteries are relatively inexpensive and easy to use, but it’s important to choose the right battery charger for the job. So, how to choose a lead-acid battery charger?
1. Which types of finished products use lead-acid batteries
Lead-acid batteries are used in a variety of different applications and certain types of equipment. Today, lead-acid batteries are used in a wide variety of applications, from emergency lighting solutions to electric pumping to prevent flooding in the event of a power failure. Perhaps the most important use of lead-acid batteries is for car ignition. They are one of the most reliable car batteries, offering higher voltages.
There is no doubt that choosing the right charger is very important for these applications. Knowing that the battery is fully charged when you need it most is its most important practical utility.
2. What is a lead-acid battery charger?
The lead-acid battery charger adopts three-stage charging, which has excellent quality, good performance and high charging saturation, which can improve the service life of the battery. Need to pass UL, CE certification, and comply with the RoHS directive.
The lead-acid battery charger has been developed to the fifth generation, using a more advanced integrated IC computer chip control system, more advanced technology, more intelligent charging process; Automatic protection, high safety factor, low heat, high efficiency, no damage to the battery, small size, light weight and easy placement. Can be used for motorcycles, electric vehicles, automobiles – 12V/1Ah-28Ah battery, battery charging.
3. Characteristics of lead-acid battery chargers
1. A charger specially designed for small lead-acid batteries, with a wide input voltage of AC100-240V;
2. The output is two alligator clips, positive and negative ends, when charging, clip the wrong poles, automatic protection, short circuit protection (no sparks);
3. The blue light is on when charging, and the red light is on when fully charged;
4. Not afraid of short circuit and misconnection, short circuit, overload, overcurrent, reverse connection automatic protection, extremely high safety factor, low heat and high efficiency;
5. Fully protect the normal use of the battery from damage to the battery due to the quality of the charger.
Fourth, the difference between lead-acid battery chargers and lithium battery chargers
The charging control method of lead-acid battery and lithium battery charger is different. The charging control of lithium battery is to charge according to constant current first, and then when the battery voltage rises to 4.2V, the voltage will no longer rise, and the charger will detect the current. If the current is less than a certain value, the charging ends. Lithium batteries are sensitive to overcharge, so the protection circuit is complicated. The maximum charging rated voltage for a single-cell nominal 3.6V battery is 4.2V, and the upper limit of the allowable error is not more than 1%.
The ideal charging current for lead-acid batteries is pulsed, and the pulsed charging is best to use the 50-60HZ mains power supply we use to directly rectify and unfiltered pulsating DC charging (this is the practice when the circuit is simple and the cost is low). The self-discharge rate of the acid battery is relatively large. When the power frequency charging is used, the constant voltage charging method is generally used.
