## Description

The **scrubber-dryer and sweeper 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.

### Frequently asked questions

### **How long do they last in daily use?**

3-5 years with 5-6 days/week use and proper overnight charging. Sulphation from leaving discharged is the #1 killer.

### **Can I switch to lithium?**

Yes, OEMs are offering factory lithium kits. Make sure the charger has a lithium profile — a GEL/AGM charger destroys lithium in weeks.
