Lithium batteries are expensive and can be damaged due to over-discharge or overcharge. Damage due to over-discharge can occur if small loads (such as alarm systems, relays, standby current of certain loads, back current drain of battery chargers, or charge regulators) slowly discharge the battery when the system is not in use.
