Product information

The maintenance-free Exide Marathon L12V32 is a 12 V AGM lead-acid battery from the Marathon L/XL series with a nominal capacity of 31.5 Ah (C10). This battery is characterised by a long service life of over 12 years (EUROBAT "Long Life"), a high power density and very low self-discharge. Thanks to its robust lead-calcium grid plates and AGM technology, it provides reliable energy for UPS systems, telecommunications, security lighting and other critical applications with medium bridging times.

Highlights at a glance

Maintenance-free: no need to top up with water (VRLA/AGM)
High power density with compact dimensions
Very low gassing (≈99 % internal recombination) & low self-discharge
Design Life: ≥12 years (EUROBAT "Long Life")
Transport without hazardous goods requirements for operational blocks (IATA A67)

Powerful 12 V performance for short to medium bridging

The L12V32 delivers reliable currents for power surges in UPS and TC applications. Typical constant current values (20 °C, final voltage per cell):

1.90 V/C: 10 min 50 A, 30 min 27 A, 1 h 17 A, 10 h 2.8 A
1.80 V/C: 10 min 70 A, 30 min 33 A, 1 h 20.2 A, 10 h 3.2 A
Constant power example (1.90 V/C, 20 °C): 585 W (10 min), 318 W (30 min), 207 W (1 h).

The short-circuit current of 966 A and an internal resistance of 13 mΩ underline its high-current capability.

Long service life, high availability, low maintenance

AGM technology enables fast recharging and long waiting times in standby operation. The minimal gas development significantly reduces ventilation and maintenance requirements. Thanks to the low self-discharge, storage and standby times are extended, making this technology ideal for emergency power and safety systems.

VRLA/AGM with robust grid plate chemistry

The electrolyte is immobilised in glass fleece (AGM). The lead-calcium grid plates ensure high corrosion resistance. With an internal gas recombination rate of approx. 99%, maintenance is reduced to a minimum. Development is according to IEC 60896-21/-22, manufacturing in ISO 9001 certified European facilities. The blocks are UL certified.

wFAQs for the Exide Marathon L12V32 battery

For which applications is the L12V32 suitable?

The L12V32 is designed for UPS systems, telecommunications, emergency and security lighting, hazard alarm technology as well as for energy and railway technology.

How long is the expected service life?

According to EUROBAT, the design life is in the "Long Life" class (≥ 12 years), depending on temperature, charge/discharge profile and installation.

Is the battery maintenance-free?

Yes, as a sealed VRLA/AGM accumulator there is no need to top up water. Regular visual and function checks in accordance with standards/manufacturer recommendation remain reasonable.

Are there any transport restrictions?

For operational blocks there are no special transport requirements according to IATA DGR, Section A67 (rail, road, sea, air).

Is there a flame-retardant version?

Yes, in addition to the standard PP housing (UL 94-HB), a UL 94-V0 variant is available.

What does “incl. MTZ” mean?

The package includes the mounting/accessory set (MTZ) for quick, standard-compliant installation (e.g. connectors/screws as per specification).
