Hi guys! So this started to happens recently, never did that before. I have a wave60 that start at 100% battery after plugged/charged all night long. after 3-4 hours of use it have dropped to 76% (100% then 92%, 84% then 76%). I left the wave on here without using it for 5min, then when I use it back after 5min and try to go forward (or reverse) the bdi from instantly from 76% to 0% witht he "charge battery" message. So.. it goes 100% to 0% in like 4 hours... normally I can do 4-5 days and its not even at 20% lol!
There is a crown tech that checked the batteries, and out of the 4 batteries this is only 1 battery that is a little bit weaker so he said the 3 other batteries need to push more to compensate for the small loss the weaker battery have. Well... is this normal? even if there is 1 battery that is a bit weaker its not suppose to drop from 100% to 0% in like 3-4 hours of use! Whats the problem? I heard to check the battery voltage when the wave will be at 0% because maybe the battery could still be full after 3 hours but the wave sees them at 0% is this true? if yes then its the bdi that is faulty? If not then I don't see how it can goes drastically to 0% in 4 hours and also going from 76% to 0% in an instant??
Thanks in advance!

I asked someone to test the overall voltage for all 4 batteries but thats when the wave was powered on and at 100%. The overall was around 25v. If I check back when the wave is dead at 0% then if batteries overall are still at 24-26v then the problem is not the batteries but a misreading from the wave?
Yes that is quite normal. I'm not sure if that tech tested the batteries under a load but sometimes one battery looks slightly weaker when idling but drops extremely when put under an electrical load. Typically I see Wave batteries last 2-4 years before needing replacement.
I would check the overall battery voltage of all 4 batteries combined idle (should be around 24-26 volts depending on charge) then check when running the hydraulics to deadhead (as high up as possible) and check the voltage while still running the motor. If it drops more than 15% from the idle battery voltage, then one or more of the batteries is dying and needs to be replaced.
I typically recommend replacing all 4 batteries if they are older than 3 years to prevent any further issues, but it is possible just to replace one at a time.
