Ambient temperature during storageAlong with the storage and operating temperature, other factors such as the duration of the storage period and the charge status during storage have a decisive influence on the possible useful life. Batteries should therefore be stored as briefly as possible, always fully charged, and within the temperature range 0 to +20 °C.

Product details

Battery module for SITOP UPS backup

The Siemens 6EP4135-0GB00-0AY0 is a 12-cell lead-acid battery module rated 12 A·h, designed as the energy storage for SITOP UPS systems. It provides DC backup power during mains loss, sized to hold up a 24 VDC bus for the duration determined by the load draw and the capacity derating curve. Capacity falls to 80 % of original capacity per EUROBAT criteria over life — a standard endurance benchmark for valve-regulated lead-acid batteries in float service. The module delivers 4 A at 20 °C typical, 2 A at 30 °C, 1 A at 40 °C, and 0.5 A at 50 °C, so the actual backup time depends on ambient temperature and discharge rate. Operating range is -15 to +50 °C; storage from -20 to +40 °C. Transport tolerance extends to +50 °C. The IP20 enclosure (253 mm wide, 201 mm high, 110 mm deep) mounts via keyhole slots for M4 screws on a flat surface — no DIN rail or S7 rail option.

Carries CE, cURus (UL 1778, CSA C22.2 No. 107.1), EAC, C-Tick, and shipbuilding approvals from ABS and DNV GL. No ATEX rating — not certified for explosive atmospheres. CSA approval is not listed.

Wiring and installation notes

Connection uses one screw terminal per polarity, accepting 0.5 to 16 mm² for +BAT and -BAT. The recommended float voltage is temperature-compensated: 28 V at 0 °C, stepping down to 26.3 V at 50 °C. DIN/VDE 0510 Part 2 / EN 50272-2 applies for ventilation and clearance — keep ignition sources at least 50 cm away.

Frequently asked questions

What approvals does this battery module carry?

CE, cURus (UL 1778, CSA C22.2 No. 107.1), EAC, C-Tick, ABS, and DNV GL. No ATEX or CSA approval.

What is the backup time at 40 °C?

At 40 °C typical, the module delivers 1 A. Backup time depends on the load; the capacity derating curve per EUROBAT applies.

Can this module be mounted on a DIN rail?

No. It uses keyhole slots for M4 screws onto a flat surface. S7 rail mounting is not supported.
