CK65 Models for Use in Hazardous Locations
An I/O cover is supplied with CK65 models marked as certified for use in hazardous 
environments. CK65 models intended for use in hazardous locations are 
identifiable by specific labeling on the back of the device.  
About the Battery
The computer uses a rechargeable Li-ion battery as its main power source. Several 
factors determine the life of your battery, such as display brightness, display 
timeout, input device, extreme temperature, and usage. Honeywell recommends 
that you keep the battery charged at all times to prevent data loss. 
CK65 computers are designed for use with standard battery model CK65-BTSC 
and cold storage battery model CK65-BTCS manufactured for Honeywell 
International Inc. CK3 battery models AB17, AB18, and 1001AB01 can also be 
used with standard CK65 models, but not with cold storage or hazardous location 
models. See the CK3 User Guide for more information. 
Note: To view specifications specific to your battery model, see the battery insert supplied 
with the battery. 
Warning:  Before you attempt to use, charge or replace the battery in CK65 
models marked for use in hazardous locations, carefully read all 
labels, markings and product documentation provided in the box or 
online at sps.honeywell.com.
Warning:  The I/O cover must be attached when using the CK65 in a hazardous 
environment.
