Must-knows about lenovo battery

Refer to the documentation that comes with your computer before installing
lenovo battery
You can replace the main battery with this Lenovo™ Battery.
To replace the main battery with the optional battery, refer to the online
information provided with your Lenovo computer.
This option package includes the following components:
• Lenovo System Battery
• Reference Guide (this book)
All personal computers manufactured by Lenovo contain a non-rechargeable
coin cell battery to provide power to the system clock. In addition many
mobile products such as notebook PCs utilize a rechargeable battery pack to
provide system power when in portable mode. Batteries supplied by Lenovo
for use with your product have been tested for compatibility and should only
be replaced with Lenovo approved parts.
Never attempt to open or service any battery. Do not crush, puncture, or
incinerate batteries or short circuit the metal contacts. Do not expose the
battery to water or other liquids. Only recharge the battery pack strictly
according to instructions included in the product documentation.
Battery abuse or mishandling can cause the battery to overheat, which can
cause gasses or flame to “vent” from the battery pack or coin cell. If your
battery is damaged, or if you notice any discharge from your battery or the
buildup of foreign materials on the battery leads, stop using the battery and
obtain a replacement from the battery manufacturer.
Batteries can degrade when they are left unused for long periods of time. For
some rechargeable batteries (particularly Lithium Ion batteries), leaving a
battery unused in a discharged state could increase the risk of a battery short
circuit, which could shorten the life of the battery and can also pose a safety
hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or
store these batteries in a discharged state.

Recommended HP 919700-850 battery care practices

Recommendations for HP 919700-850 battery usage and storage are covered in the user guide for your computer.
Additional battery care practices are as follows:
Store batteries between 20°C and 25°C (68°F and 77°F), with 70 percent charge.
Do not disassemble, crush, or puncture a battery; do not short the external contacts on a battery.
Do not leave batteries exposed to high temperatures for extended periods. Prolonged exposure to heat (inside a hot car, for example) accelerates the deterioration of cells.
Discharge the battery to 70 percent and remove the battery if you plan to store the computer (turned off and not plugged into AC power) for more than one month.
For prolonged battery storage, check the capacity every six months and recharge to 70 percent.
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 in HP Support Assistant once a month.

Simple Guidelines when Repairing HP 740715-001 Battery Packs

Only connect cells that are matched in capacity. Do not mix cells of different chemistries.
Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection circuit.
Include a temperature sensor that disrupts the charge current on high heat.
Apply a slow charge to a repaired pack to bring all cells to parity.
Pay attention when using an unknown brand. Elevated temperature hints to an anomaly.
Li-ion is sensitive to reverse polarization. Observe correct polarity.
Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time.
Check a repaired pack for self-discharge. Intrinsic defects often have high self-discharge.
