Battery And Charger; Battery Maintenance; Handling Precautions - Recharge Mower PMLI-20 Operator's Manual

Lithium-Ion rechargeable batteries require routine maintenance and care in their
use and handling. Read and follow the guidelines in this document to safely use
Lithium-Ion batteries and achieve the maximum battery life span.
Overview
1. Do not leave batteries unused for extended periods of time, either in the product or in storage. When a battery has been
unused for 6 months, check the charge status and charge or dispose of the battery as appropriate.
2. The typical estimated life of a Lithium-Ion battery is about charge cycles. One charge cycle is a period
of use from fully charged, to fully discharged and fully recharged again. Use a two to three year life expectancy for
batteries that do not run through complete charge cycles.
3. Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss
of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (cutting
time) decreases.
4. Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage. Routinely check
the battery's charge status.

BATTERY MAINTENANCE

1. Routinely check the battery's charge status.
2. Carefully monitor batteries that are approaching the end of their estimated life.
3. Consider replacing the battery with a new one if you note either of the following conditions:
-The battery run time drops below about 80% of the original run time
-The battery charge time increases significantly.
4. If a battery is stored or otherwise unused for an extended period, be sure to follow the storage instructions If you do not
follow the instructions, and the battery has no charge remaining when you check it, consider it to be damaged. Do not
attempt to recharge it or to use it. Replace it with a new battery.
STORAGE
1. Charge or discharge the battery to approximately 50% of capacity before storage.
2. Charge the battery to approximately 50% of capacity at least once every six months.
3. Store the battery at temperatures between 40°F (5 °C) and 68°F (20 °C)
NOTE:
The battery self-discharges during storage. Higher temperatures reduce the battery storage life.

HANDLING PRECAUTIONS

1. Do not disassemble, crush or punc t ure a battery.
2. Do not short the external contacts on a battery.
3. Do not dispose of a battery in fire or water.
4. Do not expose a battery to temperatures above 140 °F (60 °C)
5. Keep the battery away from children.
6. Avoid exposing the battery to excessive shock or vibration.
7. Do not use a damaged battery.
