Battery + Charger Safety 
Instructions
We pay a great deal of attention to the design of every battery 
pack to ensure that we supply you with batteries that are safe, 
durable and have a high energy density. The battery cells have 
a wide range of safety devices. Each individual cell is initially 
formatted and its electrical characteristic curves are recorded. 
These data are then used exclusively to be able to assemble 
the best possible battery packs.
Despite all the safety precautions, caution must always be 
exercised when handling batteries. The following points must 
be obeyed at all times to ensure safe use. Safe use can only 
be guaranteed if undamaged cells are used. Incorrect handling 
of the battery pack can cause cell damage.
IMPORTANT! Analyses conrm that incorrect use and poor 
care of high-performance batteries are the main factors 
responsible for personal and/or product damage.
mWARNING! Use only approved replacement batteries; 
other batteries may damage the lawn mower and cause it to 
malfunction, which can lead to serious personal injury.
mCAUTION! To reduce the risk of injury, charge the 
EcoSharp
®
 iBAT40 lithium-ion pack only in its designated 
lithium-ion charger, the iCHRG40. Other types of chargers 
present risk of re, personal injury and damage. Do not wire 
a battery pack to a power supply plug or car cigarette lighter. 
Such misuse will permanently disable or damage the battery 
pack.
• Avoid dangerous environments – Do not charge the 
battery pack in rain, snow or in damp or wet locations. 
Do not use the battery pack or charger in the presence of 
explosive atmospheres (gaseous fumes, dust or ammable 
materials) because sparks may be generated when inserting 
or removing the battery pack, which could lead to a re.
• Charge in a well-ventilated area – Do not block the 
charger vents. Keep them clear to allow for proper 
ventilation. Do not allow smoking or open ames near a 
charging battery pack. Vented gases may explode.
  NOTE: The safe temperature range for the battery is -4°F 
(-20°C) to 113°F (45°C). Do not charge the battery outside 
in freezing weather; charge it at room temperature. 
• Maintain charger cord – When unplugging the charger, pull 
the plug, not the cord, from the receptacle to reduce the 
risk of damage to the electrical plug and cord. Never carry 
the charger by its cord or yank it by the cord to disconnect 
it from the receptacle. Keep the cord away from heat, oil 
and sharp edges. Make sure the cord will not be stepped 
on, tripped over or subjected to damage or stress when the 
charger is in use. Do not use the charger with a damaged 
cord or plug. Replace a damaged charger immediately.
• Do not use an extension cord unless it is absolutely 
necessary – Using the wrong, damaged or improperly 
wired extension cord poses a risk of re and electric shock. 
If an extension cord must be used, plug the charger into 
a properly wired 16 gauge or larger extension cord with 
blades that are the same number, size and shape as the 
blades on the charger. Make sure that the extension cord is 
in good electrical condition.
• Charger iCHRG40 is rated for 120 volt AC only – The 
charger must be plugged into an appropriate receptacle.
• Use only recommended attachments – Use of an 
attachment not recommended or sold by the battery 
charger or battery pack manufacturer may result in risk of 
re, electric shock or personal injury.
• Unplug charger when not in use – Make sure to remove 
battery packs from unplugged chargers.
mWARNING! To reduce the risk of electric shock, 
always unplug the charger before performing any cleaning or 
maintenance. Do not allow water to ow into the AC/DC plug. 
Use a Ground Fault Circuit Interrupter (GFCI) to reduce shock 
hazards.
• Do not burn or incinerate battery packs – Battery packs 
may explode, causing personal injury or damage. Toxic 
fumes and materials are created when battery packs are 
burned.
• Do not crush, drop or damage battery packs – Do not 
use the battery pack or charger if they have sustained a 
sharp blow, been dropped, run over or have been damaged 
in any way (e.g. pierced with a nail, hit with a hammer, 
stepped on, etc.).
• Do not disassemble – Incorrect reassembly may pose 
a serious risk of electric shock, re or exposure to toxic 
battery chemicals. If the battery or charger are damaged,
