In recent years, sealed lead-acid batteries have undergone great development. Some lead-acid battery manufacturers have improved the structure and performance of sealed lead-acid batteries, and a number of long-life, maintenance-free and economical lead-acid batteries have appeared. Let's take a look at the characteristics of these batteries.

  Sealed lead-acid batteries are sealed maintenance-free batteries, and their valve-regulated spill-proof construction allows trouble-free, safe operation in any location. No need to add electrolytes, as the gases generated during charging recombine in a unique "oxygen cycle"

2 easy to handle

Due to the leak-proof battery construction, sealed lead-acid batteries do not require special handling precautions or shipping containers, either surface or air.

3 Economy

The materials used in sealed lead-acid batteries enable high watt-hour values ​​per dollar: they are readily available and less expensive than alternative battery chemistries such as lithium batteries.

4 long service life

The design life of sealed lead-acid batteries can range from 3 to 5 years all the way to more than 12 years, depending on the manufacturing process of the battery.

5 High discharge rate

Low internal resistance allows discharge currents up to ten times the rated capacity of the battery. Therefore, relatively small batteries can be specified in applications that require high peak current.

6 Long shelf life

The low self-discharge rate may allow a fully charged battery to be stored for up to one year, depending on storage temperature. Lead-acid batteries have a discharge temperature range of -4°F (-20°C) to 140°F (60°C) and a charge temperature range of -5°F (-15°C) to 122°F (50°C) ).

7 Deep discharge recovery

Special separator, advanced plate composition, and carefully balanced electrolyte system greatly improve the recovery ability of excessive deep discharge.
