Frequently asked questions
- The Nilfisk-Advance BU800 20B uses the battery shown on this page. Check voltage, capacity and dimensions before ordering. If there is no published price, ask for a quote and we reply the same day.
- Yes, as long as it has the same voltage, fits in the battery compartment and the Nilfisk-Advance BU800 20B charger is compatible. More capacity (Ah) means more run time; changing the voltage or battery type without adapting the charger can damage the equipment.
- Many machines run at 24, 36 or 48 V with several 6, 8 or 12 V batteries connected in series (voltages add up; the Ah capacity is that of one unit). The model page tells you how many units it takes. Always replace the whole set with identical batteries of the same age.
- Not advisable. A starter battery delivers a lot of current for a few seconds; a deep-cycle battery has thick plates built to be discharged to 50-80% and recharged every day. In traction, cleaning or mobility equipment a starter battery lasts very few cycles.
- Some references are not published in the shop: click "Request a quote" and we reply the same working day with price and lead time. Those with a price can be bought online and ship the same day if you order before 6:00 pm.
