Scrubbing Productivity & Battery Options
The Karcher BD 50/50 C Bp Classic has the same 20" cleaning path, 13.2-gallon tanks, listed productivity, and 306 lb machine weight in both battery configurations. The main choice is whether your facility prefers the lower-cost wet battery package or the maintenance-reduced AGM battery package.
Both options use the same 20" disc cleaning path.
Productivity does not change between the wet battery and AGM battery package.
Which battery package should you choose?
- Lowest starting package
- Variant SKU: MJK98413690
- 24V / 105Ah wet batteries
- Good fit when your team can maintain wet batteries properly
- Requires routine battery watering and battery maintenance
- Maintenance-reduced battery option
- Variant SKU: MJK98413700
- 24V / 100Ah AGM batteries
- Good fit when sealed AGM batteries are preferred
- Higher-cost package than the wet battery version
Choose the wet battery package for the lowest upfront cost. Choose the AGM battery package when reduced battery maintenance is more important than the lowest starting price.
Actual productivity may vary based on floor type, soil level, pad or brush selection, water flow, operator speed, battery condition, squeegee condition, dumping time, and facility traffic.
