With the development of technology, some storage battery manufacturers have been able to develop lead-acid batteries with more performance, and now the batteries have a more powerful discharge function, longer life, better anti-strike ability, and better working ability, and can even be sealed The function of the maintenance-free battery, some better batteries can have these characteristics.

(1) Sealed and maintenance-free

The valve-regulated spill-proof construction of the sealed lead-acid battery allows trouble-free, safe operation in any position. There is no need to add electrolytes, as the gases produced 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 the high watt-hour value per dollar: they are readily available and less expensive than alternative battery chemistries such as lithium batteries.

(4) long service life

Sealed lead-acid batteries can be designed to last anywhere from 3 to 5 years all the way up to over 12 years, depending on the battery's manufacturing process. There are many factors that affect battery life.

(5) Design flexibility

Sealed lead-acid batteries can be used in series and/or parallel for a choice of voltage and capacity. Thanks to a recent design breakthrough, the same battery can be used for cycling or standby applications.

(6) Solid structure

The high-impact battery case is made of non-conductive ABS plastic. High-capacity batteries often have polypropylene casings; all of these materials are highly resistant to shock, vibration, chemicals, and heat.

(7) 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 requiring high peak current.

(8) Long shelf life

The low self-discharge rate may allow a fully charged battery to be stored for up to a year, depending on storage temperature.

(9) Wide operating 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) ).

(10) Deep discharge recovery

   The special separator, advanced plate composition, and carefully balanced electrolyte system greatly improve the recovery ability of excessive deep discharge, and the performance of the deep cycle gel battery is even more obvious.
