17.4 Replacing the Internal Battery<br />

Caution Fire, explosion, and severe burn hazard! Misuse or improper<br />

installation of the lithium battery can cause severe injury. Do not<br />

recharge, disassemble, heat above 100°C (212°F), solder directly to the<br />

cell, incinerate, or expose contents to water. Dispose of spent lithium<br />

batteries properly.<br />

The <strong>CR200</strong>(X) contains a lithium battery that operates the clock and SRAM<br />

when the <strong>CR200</strong>(X) is not powered. The <strong>CR200</strong>(X) does not draw power from<br />

the lithium battery while it is powered by an external source. In a <strong>CR200</strong>(X)<br />

stored at room temperature, the lithium battery should last approximately 5<br />

years (less at temperature extremes). Where the <strong>CR200</strong>(X) is powered most or<br />

all of the time the lithium cell should last much longer.<br />

The internal lithium battery must be replaced periodically. Factory replacement<br />

is recommended. Contact <strong>Campbell</strong> <strong>Scientific</strong> to obtain an RMA prior to<br />

shipping the <strong>CR200</strong>(X).<br />

If the lithium cell is removed or allowed to discharge below the safe level, the<br />

<strong>CR200</strong>(X) will still operate correctly while powered. Without the lithium<br />

battery, the clock will reset and data is lost when power is removed.<br />
