The CF-33 ships in two distinct bottom panel configurations: a <strong data-start=\"3454\" data-end=\"3477\">standard flat panel<\/strong> \u0648 \u0623 <strong data-start=\"3484\" data-end=\"3505\">tall bottom panel<\/strong>. These are not interchangeable covers. The tall bottom panel is physically thicker, creating a larger internal cavity that accommodates the CF-VZSU1BW&#8217;s 3-cell, 45Wh pack. The standard flat panel cannot physically close over the CF-VZSU1BW. This is not a nuance \u2014 ordering CF-VZSU1BW batteries for a CF-33 fleet that shipped with flat panels creates a parts-incompatibility problem at the depot that no amount of rework resolves without sourcing the correct covers.<\/p>\n<p data-start=\"3973\" data-end=\"4011\">Compare the two CF-33 battery options:<\/p>\n<ul data-start=\"4013\" data-end=\"4263\">\n<li data-start=\"4013\" data-end=\"4113\">\n<p data-start=\"4015\" data-end=\"4113\"><a href=\"https:\/\/www.balderpower.com\/ar\/panasonic-cf-vzsu1ajs-battery-replacement\/\"><strong data-start=\"4015\" data-end=\"4029\">CF-VZSU1AW<\/strong><\/a> \u2014 Standard Battery: 22Wh \/ 1,990mAh \/ flat panel \/ ~5 hours single \/ ~10 hours dual<\/p>\n<\/li>\n<li data-start=\"4114\" data-end=\"4263\">\n<p data-start=\"4116\" data-end=\"4263\"><strong data-start=\"4116\" data-end=\"4130\">CF-VZSU1BW<\/strong> \u2014 Long Life Battery: 45Wh \/ 4,120mAh \/ tall panel required \/ ~8\u201310 hours single (MK1) \/ ~7 hours (MK2\u2013MK4) \/ up to <strong data-start=\"4246\" data-end=\"4263\">20 hours dual<\/strong><\/p>\n<\/li>\n<\/ul>\n<p data-start=\"4265\" data-end=\"4847\">The Long Life Battery delivers more than double the capacity of the Standard Battery per unit. In dual configuration \u2014 two CF-VZSU1BW units installed simultaneously, one in the tablet section and one in the keyboard base \u2014 the CF-33 delivers Panasonic&#8217;s published maximum of approximately 20 hours combined runtime on MK1 hardware. That figure positions the CF-33 with dual Long Life batteries as one of the longest-running rugged 2-in-1 platforms in the market, relevant for public safety operations, military field logistics, and remote utility crews running extended deployments.<\/p>\n<p data-start=\"4849\" data-end=\"5314\">One additional procurement detail: the <strong data-start=\"4888\" data-end=\"4932\">CF-33 also supports mixed configurations<\/strong> \u2014 one CF-VZSU1AW (Standard) and one CF-VZSU1BW (Long Life) installed simultaneously. This is possible because each position has its own cover. A CF-33 unit with a tall panel in the keyboard base and a flat panel in the tablet section can run one of each. Procurement teams ordering for mixed-configuration fleets need to account for both cover types when specifying battery orders.<\/p>\n<p data-start=\"5316\" data-end=\"5409\"><strong data-start=\"5316\" data-end=\"5359\">\u0623\u0631\u0642\u0627\u0645 \u0627\u0644\u0642\u0637\u0639 \u0627\u0644\u0645\u062a\u0648\u0627\u0641\u0642\u0629 \u0627\u0644\u062a\u064a \u062a\u0645 \u0627\u0644\u062a\u062d\u0642\u0642 \u0645\u0646\u0647\u0627 (P\/N):<\/strong><br \/>\nCF-VZSU1BW \u00b7 CF-VZSU1BR \u00b7 CF-VZSU1BJS \u00b7 CFVZSU1BW<\/p>\n<p data-start=\"5411\" data-end=\"5442\"><strong data-start=\"5411\" data-end=\"5442\">\u0627\u0644\u0637\u0631\u0627\u0632\u0627\u062a \u0627\u0644\u0645\u062a\u0648\u0627\u0641\u0642\u0629 \u0627\u0644\u062a\u064a \u062a\u0645 \u0627\u0644\u062a\u062d\u0642\u0642 \u0645\u0646\u0647\u0627:<\/strong><\/p>\n<div class=\"TyagGW_tableContainer\">\n<div class=\"group TyagGW_tableWrapper flex flex-col-reverse w-fit\" tabindex=\"-1\">\n<table class=\"w-fit min-w-(--thread-content-width)\" data-start=\"5444\" data-end=\"5817\">\n<thead data-start=\"5444\" data-end=\"5499\">\n<tr data-start=\"5444\" data-end=\"5499\">\n<th class=\"\" data-start=\"5444\" data-end=\"5457\" data-col-size=\"sm\">Generation<\/th>\n<th class=\"\" data-start=\"5457\" data-end=\"5478\" data-col-size=\"sm\">Processor Platform<\/th>\n<th class=\"\" data-start=\"5478\" data-end=\"5499\" data-col-size=\"sm\">Panel Requirement<\/th>\n<\/tr>\n<\/thead>\n<tbody data-start=\"5514\" data-end=\"5817\">\n<tr data-start=\"5514\" data-end=\"5588\">\n<td data-start=\"5514\" data-end=\"5526\" data-col-size=\"sm\">CF-33 MK1<\/td>\n<td data-start=\"5526\" data-end=\"5558\" data-col-size=\"sm\">Intel Core i5-7300U (7th gen)<\/td>\n<td data-col-size=\"sm\" data-start=\"5558\" data-end=\"5588\">Tall bottom panel required<\/td>\n<\/tr>\n<tr data-start=\"5589\" data-end=\"5663\">\n<td data-start=\"5589\" data-end=\"5601\" data-col-size=\"sm\">CF-33 MK2<\/td>\n<td data-start=\"5601\" data-end=\"5633\" data-col-size=\"sm\">Intel Core i5-8365U (8th gen)<\/td>\n<td data-start=\"5633\" data-end=\"5663\" data-col-size=\"sm\">Tall bottom panel required<\/td>\n<\/tr>\n<tr data-start=\"5664\" data-end=\"5740\">\n<td data-start=\"5664\" data-end=\"5676\" data-col-size=\"sm\">CF-33 MK3<\/td>\n<td data-start=\"5676\" data-end=\"5710\" data-col-size=\"sm\">Intel Core i5-10310U (10th gen)<\/td>\n<td data-start=\"5710\" data-end=\"5740\" data-col-size=\"sm\">Tall bottom panel required<\/td>\n<\/tr>\n<tr data-start=\"5741\" data-end=\"5817\">\n<td data-start=\"5741\" data-end=\"5753\" data-col-size=\"sm\">CF-33 MK4<\/td>\n<td data-start=\"5753\" data-end=\"5787\" data-col-size=\"sm\">Intel Core i5-1145G7 (11th gen)<\/td>\n<td data-start=\"5787\" data-end=\"5817\" data-col-size=\"sm\">Tall bottom panel required<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<p data-start=\"5819\" data-end=\"6133\">\u26a0\ufe0f <strong data-start=\"5822\" data-end=\"5850\">Before ordering in bulk:<\/strong> Physically inspect each CF-33 unit or check the original purchase configuration to confirm tall bottom panel.
