Recommendations for battery usage and storage are included in the user guide for your computer. Additional battery care practices are as follows:

Store batteries for EliteBook 840R G4 between 20°C and 25°C (68°F and 77°F) with 80 - 90% charge.
Do not disassemble, crush, or puncture a battery and do not short the external contacts on a battery.
