A used stairlift I purchased has two Genesis NP7-12FR 12volt, 7.0 AH.. batteries for operating the lift. These 2 batteries are connected in series to drive the lift's 24 volt motor. The Genesis Application Manual for the NP and NPX batteries shows the NP7 can actually produce 20 amps for about 6 minutes at 3 CA ( 21 amps?) before the terminal voltage decreases to 9 volts.
Can anyone give me an idea of what the battery amps drain would be when going up and down a set of stairs. I'm aware that the steepness of the stairs, the weight of a person, and other subtle factors are variables. But I'm just interested in a general range of the amperage drain unless more specific test data is available.
I've searched the Internet without success so far.
