12V 20AH Sealed Lead Acid Batteries
12V20AH sealed lead acid battery is a battery whose electrode is mainly made of lead and its oxide, and the electrolyte is a sulfuric acid solution.
12V20AH sealed lead acid battery is a battery whose electrode is mainly made of lead and its oxide, and the electrolyte is a sulfuric acid solution. It is fully sealed, does not leak acid, and does not emit acid mist like traditional lead-acid batteries to corrode equipment and pollute the environment. The top has a resealable plastic closure with venting holes. This sealed lead acid battery has the advantages of low cost, easy availability of raw materials, and sufficient reliability in use, so it can be applied to high current discharge and a wide range of ambient temperatures.
The sealed lead acid battery can be used freely without acid or hydration.
The optimized manufacturing process extends service life and is highly resistant to shock, vibration, chemicals and heat.
The high impact battery case is made of non-conductive ABS plastic, sealed with modified epoxy resin sealant, anti-corrosion and no acid leakage.
The electrolyte is made of high purity sulfuric acid and special additives to ensure maximum electrode performance and to suppress short circuits and self-discharge.
The gel battery has advanced sealing structure, no expansion, no electrolyte concentration stratification, strong charging acceptance, less water loss, strong anti-overcharge capability and strong charge retention capability.
