Nickel Metal Hydride (NiMh) Approx 1% per day if unused.
A NiMH battery can lose up to 2% of its charge per day sitting on the shelf.
18. What is the self-discharge rate of NiMH batteries? In general, the rate of self-discharge ranges from 15% to 20% per month at room temperature.
NiMH batteries self-discharge up to 20% in the first 24 hours after charging, then as much as 15% per month. Self-discharge is highly temperature dependent. NiMH batteries self discharge about three times faster at 40 °C than at 20 °C. Age also affects self-discharge. Older battery packs self-discharge faster than new ones.
NiMh batteries tend to self-discharge at 3–4% of capacity per day.
