The battery is great for heavy use with its leak-proof, high power, and starting ability. There have 4 advanced technology being used in producing, they are Grid Production Technology, AGM Technology, Lead-Carbon Capacitance Technology and High Assembly Pressure Design. Adopting the lead-carbon capacitance technology, the battery’s charge acceptance is significantly improved, therefore, it can more quickly capture the feedback current from vehicle. High assembly pressure design can slow the positive paste shedding and prolong its life time greatly. Besides, the starting life is more than 200,000 times, 2 times longer than ordinary battery. It has a wide operating temperature range of -30℃( -22℉) to 70℃( 158℉). The battery reduce the self-discharge rate below 8% at 25℃( 77℉) after 90 days storage. It is widely used in mild hybrids vehicles with Start-Stop system.

AGM70 12/70 (group 27)


In AGM batteries, the electrolyte (mixture of water and sulphuric acid) is largely absorbed in glass fibre. This type of battery is entirely maintenance-free and there is no gas formation with normal use. AGM batteries can be installed anywhere.

Their construction gives a very fast discharge at very high currents so AGM batteries are ideal for systems that require high currents (for instance when starting an engine). The battery poles can be unscrewed and this type of battery can be combined with every standard battery terminal.

  • Excellent starter function.
  • Perfect upgrade for flooded lead acid batteries.
  • Same initial power surge in an AGM 12/90 Ah as 180 Ah flooded lead-acid battery.
  • Glass-fibre technology ensures low internal resistance.
  • Use of thicker plates extends lifespan.
  • Can be combined with every standard battery terminal.
  • Also for medium cyclical use.
  • Two year warranty.

How 12v 70 Ah Agm Battery is Used in the Automotive Industry

Agm70 12V 70 AH AGM battery is commonly used in the automotive industry as the main power source for starting the engine and powering various electrical systems in the vehicle.

In an automotive application, the 12V 70AH car battery is typically used as a starting battery, providing the initial surge of power needed to turn over the engine and get it running. Once the engine is started, the battery is then recharged by the alternator, which converts mechanical energy from the engine into electrical energy to replenish the battery’s charge.

In addition to starting the engine, the 70AH 12V stop start battery is also used to power various electrical systems in the vehicle, such as the lights, audio system, and HVAC (Heating, Ventilation, and Air Conditioning) system. It may also provide backup power in case the alternator fails or the vehicle’s electrical system experiences a temporary power loss.

How to Properly Maintain and Care for Your Agm70 70AH Battery

Proper maintenance and care are essential for ensuring the longevity and performance of your AGM 70AH 12Vbattery. Here are some tips for maintaining and caring for your battery:

Regular Charging

12V 70AH AGM battery should be charged regularly, even when not in use. This helps prevent sulfation, a process that can lead to reduced battery capacity and shortened lifespan. A high-quality charger designed for AGM batteries should be used to ensure proper charging and avoid overcharging.

Avoid Over-Discharging

Over-discharging can cause irreversible damage to AGM batteries, leading to reduced capacity and shortened lifespan. Avoid running your battery down to the point where it can no longer power your equipment. If you are using the battery for backup power, make sure to recharge it as soon as possible after use.

Keep the Battery Clean

Dirt and debris can accumulate on the surface of the battery and cause corrosion, reducing its lifespan. Regularly clean the battery using a damp cloth or a battery cleaner solution, being careful not to get any water or cleaning solution inside the battery.

Store the Battery Properly

If you are storing your 70AH 12V stop start battery for an extended period of time, make sure to store it in a cool, dry location away from direct sunlight. Keep the battery charged to around 50% of its capacity during storage to prevent self-discharge.

Perform Regular Inspections

Inspect your battery regularly for signs of damage, including cracks, leaks, and swelling. If you notice any damage, replace the battery immediately to prevent further damage or safety hazards.

Avoid Overloading

Overloading your AGM battery can cause it to overheat and reduce its lifespan. Make sure to use the battery with equipment that matches its rated capacity, and avoid running multiple devices off of the battery at the same time.
