The **scrubber-dryer battery** for Karcher, Hako, Tennant, Numatic, Nilfisk, Comac, Fimap, IPC, Adiatek, Fiorentini works in punishing conditions: daily deep discharges, water and detergent nearby, damp air, unattended overnight charging. Standard: **24-36 V GEL or deep cycle AGM bank**, 100-240 Ah, sealed, zero emissions, no water top-up — essential where the machine works in food, healthcare or climate-controlled facilities. ## GEL vs AGM in industrial scrubbers **GEL** is the classic scrubber choice: tolerates very deep discharges (up to 80% DoD without major penalty) and works fine with older chargers. **Deep cycle AGM** is the modern benchmark: more Ah per kg, better cold weather, faster charge. Both are sealed, maintenance-free, mountable in any orientation. **Never mix chemistries** in one bank — the charger is calibrated for one only. ### Table by model | Model | Bank | Typical capacity | Type | |---|---|---|---| | Karcher BD 50/70 / BR 55/40 | 24 V | 100-160 Ah | GEL / AGM | | Karcher KM 75/40 / KM 90/60 | 24 V | 105-180 Ah | GEL / AGM | | Hako Hakomatic B 75 / B 175 | 24-36 V | 140-240 Ah | GEL / AGM | | Tennant T300 / T500 / T7 | 24-36 V | 105-240 Ah | GEL / AGM | | Numatic TT3450 / TGB3450 | 24 V | 105-160 Ah | GEL / AGM | | Comac Innova 55B / Optima | 24-36 V | 110-240 Ah | GEL / AGM | ### Leading brands - [MK Battery 8GU1H / 8G27 / 8G31](https://baterias.com/gb/batteries-mk) — global GEL reference for professional cleaning. - [Fullriver DC AGM](https://baterias.com/gb/batteries-fullriver) — sealed AGM equivalent. - [Trojan T-105 / T-1275](https://baterias.com/gb/batteries-trojan) — flooded option for ventilated warehouses. ### Frequently asked questions ### **How long do they last in daily use?** 3-5 years with 5-6 days/week use and proper overnight charging.
