Since the internal resistance is low .the ESG 12v250ah high quality solar battery can provide high rate of discharge.
.ESG 12v250ah high quality solar battery-Wide operation temperature range
ESG 12v250ah high quality solar battery capacity is rated at 20°C , and will operate from 15°C (5f)+50°(C (122F)when it is fully charged Ambient temperature is 20°C.service life will be more efficient under 15’C to gel deep cycle ESG 12v250ah high quality solar battery for solar street light.
2.ESG 12v250ah high quality solar battery Construction
Parts | Material | Function |
Positive plates | Lead - calcium alloy with special chemical formula. | Retain sufficient capacity. Maintain capacity performance for long period of time (long life performance). Minimize self-discharge. |
Negative plates | Lead - calcium alloy with special chemical formula. | Retain sufficient capacity. Maintain capacity performance for long period of time (long life performance). Minimize self-discharge. |
Separator | The advanced medium porous Absorbed Glass Mat (AGM) or PVC separators retain electrolyte and prevent shorting between positive and negative plates. Separators adopt a non-woven fabric of fine glass fibers, which is chemically stable in the diluted sulfuric acid electrolyte. Being highly porous, separators retain electrolyte for the reaction of active materials in the plates. | Prevents short circuit between positive and negative plates. Retains electrolyte. Prevents active material fall by pressing plate surfaces. |
Electrolyte | Acid Electrolyte | The Electrolyte is used as the medium for conducting ions in the electro-chemical reaction in the battery. |
Container & Cover | Usually, it should be ABS resins. But can do as client’s request. | Accommodates plate group consisting of positive and negative plates and separators. Retains sufficient mechanical strength to withstand ESG 12v250ah high quality solar battery internal pressure. |
Safety valve | In cap shape. The valve is comprised of the one-way valve, which is made of material such as neoprene. | Releases gas if cell internal pressure rises abnormally high and normalizes internal pressure. Prevents ingress of oxygen. |

7.Our Standard Product Flow & testing part -.ESG 12v250ah high quality solar battery
• The ESG 12v250ah high quality solar battery electrolyte contains fumed silica, and there is no flow, no leakage or no gradation of acid liquor. The ESG 12v250ah high quality solar battery slot and cover is made of ABS materials through hot seal. There is no risk of leakage during the utilization and transportation, and it is safe and reliable.
• The gel electrolyte is in dilute sol state when being injected. Excessive electrolyte can fill in all the space inside battery. Under circumstance of high-temperature and overcharge, the ESG 12v250ah high quality solar battery will not dry out. The gel ESG 12v250ah high quality solar battery has large heat capacity and good radiation performance. It is not easy to appear thermal runaway. The ESG 12v250ah high quality solar battery can work under severe environment.
• The grid of electrode plate is in radial structure, which is favorable for improving the utilization rate of active materials. Pb-Ca-Sn-Al alloy makes the positive plate have a good performance of corrosion proof and makes the negative plate have a high over-voltage of hydrogen evolution. Unique lead paste formula enables perfect recovery performance of ESG 12v250ah high quality solar battery recharging after deep discharging. The ESG 12v250ah high quality solar battery has strong cycle and duration performance, sufficient capacity and long life.
• The terminal is in the structure of tin electrodeposited copper terminal, which is favorable for discharging ESG 12v250ah high quality solar battery with large current and is favorable for the reliability of connection between ESG 12v250ah high quality solar battery . The terminal is sealed through fusion welding and second seal of resin sealant, and the seal reliability is high.
