Lithium Polymer (Lipo) Battery Guide
Low Self-Discharge – When not in use, batteries can slowly discharge. Lipos have a low self-discharge rate of approximately 5% per month. In contrast nickel metal hydride (ni-mh) cells typically see 30% per month and 10% for nickel cadmium (ni-cd) batteries.

Battery researchers find possible reason for self-discharge
In lithium-ion battery cells, coiled electrodes of these batteries are held together with simple PET adhesive tape. At higher temperatures in the battery, this plastic decomposes to form dimethyl terephthalate (DMT) – and this molecule acts like an "electrochemical shuttle" that discharges the battery.

Uncovering the Relationship between Aging and Cycling on Lithium Metal Battery Self-Discharge
Understanding the various mechanisms of self-discharge is also critical for realizing practical lithium metal batteries but is often overlooked. In contrast to previous work, it is shown here that self-discharge via galvanic corrosion is negligible, particularly when lithium is cycled to relevant capacities.
How to store lithium based batteries
If the battery is fitted with a safety circuit (and most are) this will contribute to a further 3% self-discharge per month. Lithium batteries should be kept at around 40-50% State of Charge (SoC) to be ready for immediate use – this is approximately 3.8 Volts per cell – while tests have suggested that if this battery type is kept fully ...
