Replacing the battery is straightforward, but because this equipment relies on older NiMH or NiCd battery technology, it requires a little extra care. Here is a quick, safety-first troubleshooting guide to help get your total station back up and running smoothly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Diagnosing the Issue (Is it Really the Battery?)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before you order a replacement, make sure the battery is actually the culprit.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Check the contacts:<\/strong>\u00a0Inspect the metal terminals on the battery pack and inside the total station compartment. Are they dirty, green, or corroded? Sometimes a quick wipe with an alcohol swab or a gentle rub with a pencil eraser is all it takes to restore the connection.<\/li>\n\n\n\n<li><strong>Test the charger:<\/strong>\u00a0If the charger light doesn\u2019t come on, you might just need a new BC-19 charger rather than a new battery.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the terminals are clean and the charger works perfectly, but the battery dies after just 10 minutes of use, it is time for a replacement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Finding a Safe Replacement<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Finding a brand-new, original battery for a&nbsp;<a href=\"https:\/\/www.batteryone.co\/detail\/1745800\/BT-32Q\">GTS-200<\/a>&nbsp;can be difficult today. You will most likely need to choose a third-party aftermarket battery. Keep these safety tips in mind when shopping:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Match the specs:<\/strong>\u00a0Ensure the replacement battery is rated at exactly 7.2V.<\/li>\n\n\n\n<li><strong>Consider repacking:<\/strong>\u00a0If you want to keep your original plastic housing, some specialized electronics repair shops can repack your old battery by opening the case and soldering in fresh NiMH cells.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Safe Replacement Process<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Replacing the battery on the GTS-200 is very simple, but working safely and carefully prevents damage to the instrument&#8217;s internal calibration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Power Down First<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Never try to remove the battery while the instrument is turned on. Turn off the total station using the power button and wait a few seconds until the internal system shuts down completely.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Release and Remove the Battery<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Locate the battery release lever on the side of the instrument. Press or slide the release mechanism firmly but gently. The battery pack should pop loose. Carefully slide it out.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Inspect the Internal Compartment<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With the battery out, look inside the empty slot. Make sure there is no dust or moisture. If you are working in the rain or a dusty environment, try to perform the swap inside a vehicle or under cover.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Install the New Battery<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Align the rails on the new battery pack with the slot on the total station. Slide it in until you hear a distinct click. Give it a gentle tug to ensure it is locked into place. You definitely do not want the battery dropping into the mud in the middle of a job!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Important Safety Reminders<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Dispose of old batteries safely:<\/strong>\u00a0Do not throw your old BC-19 battery into the regular trash. NiCd and NiMH batteries contain heavy metals. Please take them to a local electronics recycling center.<\/li>\n\n\n\n<li><strong>Avoid extreme temperatures:<\/strong>\u00a0Never leave your battery baking on a truck dashboard or freezing overnight in the cab. Extreme temperatures will rapidly degrade battery capacity.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Ready to get back to work?
