Scientists have attempted to replace cobalt in lithium-ion batteries with metals like nickel and magnesium. However, these alternatives tend to have higher rates of self-discharge—where the battery''s internal chemical reactions deplete stored energy, causing capacity to decline over time.
Besides their promising electrochemical performance, the low self-discharge rate (<5% of the stored capacity over 1 month) of lithium-ion batteries is one of their most significant advantages for ESSs. Herein, contrary to conventional belief, we report that the self-discharge of LIBs can be abnormally accelerated when the battery has been ...
High energy density and stable long cycle are the basic requirements for an ideal battery.

I had the first battery replaced with a brand new lithium battery and the same issue is happening. I will post pictures later, but the only thing I can think of is the small draw on the battery while the cart is off from the lights on the dash. Although, that would not explain why the battery holds a charge until around 60% and then goes to 0% overnight.
