When it comes to sealed lead-acid batteries, everyone may be relatively unfamiliar or have no clear concept. What is the difference between it and ordinary chargers? Today, we will lead you to learn about the difference between them in detail through this article:
Ordinary chargers are usually designed to provide fixed voltage or current, suitable for general battery types, such as nickel-metal hydride batteries, lithium batteries, etc. These batteries have relatively simple requirements for charging voltage and current, and the control standards are relatively loose. Sealed lead-acid battery chargers need to strictly control the output voltage and current to ensure that the battery can be charged safely.
Management of the charging process
The charging process of sealed lead-acid batteries is relatively complicated, and the charger needs to be managed in stages. First, there is the constant current charging stage, where the charger provides a fixed current until the battery voltage reaches the set value; then it enters the constant voltage charging stage, maintaining a fixed voltage and gradually reducing the charging current until the battery is fully charged; and finally, there is the floating charging stage, where a lower current is provided to maintain the battery voltage to prevent overcharging. Ordinary chargers usually do not have this multi-stage management function, which may lead to problems such as battery overcharging and overheating.
Protection function
Sealed lead-acid battery chargers usually have more safety protection functions, such as short circuit protection, overcurrent protection, and overtemperature protection. These functions can effectively prevent the battery from being damaged or causing safety accidents due to abnormal conditions during the charging process. Although ordinary chargers also have some basic protection functions, they usually do not have complex protection mechanisms for specific battery types (such as lead-acid batteries). In general, in terms of safety performance, sealed lead-acid battery chargers are more comprehensive than ordinary chargers.
Charging method
Sealed lead-acid battery chargers generally adopt the "intelligent charging" method, which can automatically adjust the charging strategy according to the battery charging status to avoid overcharging and extend the battery life. Ordinary chargers generally do not have this intelligent adjustment function, and the charging process is simpler and more crude.
