Chapter 2 – Hardware Operation

Batteries beyond one year of service may experience shorter run times. WalkAbout recommends replacing your batteries once a year or every 400-500 charge/discharge cycles for optimal battery performance.

Where to purchase replacement batteries

The Hammerhead uses long lasting Lithium Ion batteries that are custom made for WalkAbout Computers. If you need to purchase replacement batteries for your Hammerhead computer, contact your WalkAbout sales representative. Do not substitute any other batteries. Substituting batteries may result in a void warranty.

How to store batteries when they’re not in use

The following storage tips will help you optimize the capacity and performance of your batteries.

•If the battery will not be in use for a month or longer, it is recommended that it is removed from the computer for storage.

•Store batteries in a cool, dry place.

•Do not leave batteries in direct sunlight during the summer months or any other unusually hot location.

•Do not expose battery terminals to metal objects or moisture, which may short-circuit your battery.

•For long-term storage, store batteries below 50% state of charge because the deterioration of battery capacity is slower at lower state of charge. However, do not store batteries in a fully discharged state.

The safety circuit in your battery cannot protect against handling abuse. Please use the following safety rules when handling and using Lithium Ion batteries.
