Recommendations for HP ENVY 17-U275CL battery usage and storage are included in the user guide for your computer. Additional battery care practices are as follows:
- Store HP batteries 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.
- WARNING: Keep batteries away from children. Batteries can be a choking and poison hazard.
- Do not leave batteries exposed to elevated temperatures for extended periods. Prolonged exposure to heat (inside a hot car, for example) accelerates the deterioration of battery cells.
- Long term battery storage:
- Charge or discharge the battery to 80 - 90%.
- Place the HP ENVY 17-U275CL notebook into ship mode per your user guide. Refer to your notebook user guide to determine if your computer supports this feature.
- Check the battery charge every three months. If the battery charge falls below 50%, charge the battery to 80 - 90%, and then repeat the steps in the user guide to put the computer back into ship mode.
- NOTE: For the steps to put a business computer into ship mode, go to the Battery storage recommendations section in this document.
- For best performance, use only the battery provided with the computer, a replacement battery provided by HP, or a compatible battery purchased as an accessory. If you have a choice of battery types to use with your computer, use the type of battery with the highest capacity rating.
- To maintain the battery, run Battery Check using HP Support Assistant. Under normal usage, batteries should be calibrated a minimum of once every two to three months. However, a battery that is rarely discharged fully should be calibrated about once a month.
