SITOP BAT1600 battery module for SITOP UPS1600, 24V DC, 12Ah maintenance-free lead-acid battery.
Siemens 6EP4135-0GE00-0AY0 is a SITOP BAT1600 battery module for the SITOP UPS1600 system, containing a maintenance-free 24 V DC, 12 Ah sealed lead-acid battery. It delivers a rated output current of 40 A, a 120 A peak for 30 ms, and a maximum charging current of 3 A, with short-circuit protection via a 50 A/32 V fuse.
The 12 Ah capacity and 4-year typical service life at 20C set the buffering window for connected loads; that service life falls to 2 years at 30C and 1 year at 40C, so replacement intervals should follow actual cabinet ambient temperature rather than the nominal 4-year figure. The 120 A/30 ms peak rating covers inrush current at UPS transfer, and the 50 A/32 V fuse sets the practical output short-circuit protection level for the module.
Battery backup for SITOP UPS1600-based 24 V DC bus supplies, bridging brief mains interruptions for PLC and controller loads, and marine or offshore 24 V UPS installations covered by ABS shipbuilding approval.

| ambient condition | For storage, mounting and operation of lead-acid batteries, the relevant DIN/VDE regulations or country-specific regulations (e.g. VDE 0510 Part 2/EN 50272-2) must be observed. You must ensure that the battery site is sufficiently ventilated. Possible sources of ignition must be at least 50 cm away. |

| service life of energy storage: at 50 °C typical | 0.5 a |
| note | Along 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. |
