AGM akkumulátor 12 V 90 Ah

This battery uses AGM (Absorbed Glass Mat) technology. In this type of battery, the electrolyte (a mixture of water and sulfuric acid) is fully absorbed into glass fiber separators, making it maintenance-free and without gas emissions during normal use.

The main advantages of this AGM battery are:

It requires no maintenance and does not release gas during normal use. It offers excellent high-discharge capacity at high currents, making it ideal for engine starting. It has low internal resistance thanks to its fiberglass technology, optimizing power delivery. It has an extended lifespan due to the use of thicker plates. It can be installed in any position (though vertical is recommended) and is a perfect replacement for wet lead-acid batteries.

The nominal voltage of this battery is 12 volts.

The nominal capacity of this battery, measured over 20 hours (C20), is 90 Ah.

The weight of this battery is 28 kg.

The external dimensions of this battery (length x width x height, including handles and excluding automotive-type terminals) are 330 x 173 x 220 mm.

Yes, this battery is perfectly suited for engine starting. Its AGM design provides excellent high-current discharge capacity, delivering starting power equivalent to that of a 180 Ah flooded lead-acid battery.

No, thanks to its AGM technology, this battery is maintenance-free. The electrolyte is absorbed into the glass fiber, eliminating the need to check or top up the water level. However, it is recommended to keep it clean and charged.

This battery is fitted with M8 / type A terminals, which are removable and compatible with all standard battery terminals.

For battery installation, it is recommended to:

Install it in a vertical position.Maintain at least 1 cm spacing between batteries.Keep it away from heat sources.Ensure adequate ventilation if installed in a confined space, as an explosive hydrogen gas mixture may escape in case of overcharging.

The recommended torque for terminal connections is 14.7 to 19.6 Nm.

Yes, it is possible to connect several of these batteries in series or parallel. However, all connected batteries must be of the same brand, same type, same capacity, and same state of charge. It is important not to mix new and old batteries.

In case of overload, lead-acid batteries can release an explosive mixture of hydrogen gas. If the battery is installed in an enclosed space, it is imperative to ensure adequate ventilation to prevent any risk of explosion or fire.

It is imperative to use only chargers with an IUoUo characteristic to charge this AGM battery.

Recommended charging voltages at 25°C are:

For float charge: 13.80 V. For absorption charge: 14.25 V (for a maximum of 5 hours).

Yes, a temperature-compensated charge is highly recommended for this battery, with a setting of -30 mV/°C.

This battery is covered by a two-year warranty.

To keep the battery in good condition and extend its lifespan:

Check the battery and its connections regularly (at least every three months), and correct any faults immediately. Keep the battery charged. Recharge the battery if its open-circuit voltage drops below 12.3 Volts. Avoid deep discharges; regular discharges beyond 50% of the rated capacity are not recommended. Recharge the battery immediately after each discharge and never discharge it below the final discharge voltage. Keep the battery dry and clean using a soft, damp cloth. Never use additives, acids, or abrasive products. Never open the battery or add acid or distilled water.
