Quoted from marioparty34:How many of you still use the original battery? I have had mine for a little over 18 months and it seems like its not keeping the charge very well.
Using it just a few times up and down 18 steps takes about 1/4 of the charge.
I have the original battery from 2014 on mine. Fully charged I removed a heavy jukebox from a basement last week and it just seemed to struggle the last couple steps. Not bad being I have pulled over 100 machines from basements in the 6 years I have owned it. Time to replaced my battery.
