There are <strong>two completely different generations of Latitude 3450<\/strong> with incompatible batteries, this article covers the older 2015 Latitude 3450 (5th Gen Intel Core, widely sold in refurbished markets) using <a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-3450-replacement-battery.html\"><strong>TRHFF<\/strong><\/a> battery. Do not mix it with the new 2024 Latitude 3450 which uses DR02P \/ R73TC series batteries.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Dell Latitude 3450 (2015) is a durable entry business laptop for office, school and field work. Powered by 5th Gen Intel Core i3\/i5\/i7 processors, it remains a popular refurbished unit. Its internal lithium-ion battery is the most common worn-out part after years of daily charge cycles. This guide includes&nbsp; specs, hands-on runtime testing, installation notes and full FAQ.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dell only offered one factory battery solution for this 2015 Latitude 3450 chassis: <strong>TRHFF, 58Wh, 4-cell, 11.1V Li-ion<\/strong>. Cross reference PN: <strong>0TRHFF, 1V2F6, 01V2F6, PD19, 0PD19, 58DP4<\/strong>. This battery also fits Latitude 3550, Inspiron 5542, 5543, 5545, 5547, 5548. There is no alternative smaller or higher-capacity&nbsp; battery for this chassis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hands-on Product Review<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We tested a certified <a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-3450-replacement-battery.html\">replacement TRHFF 58Wh battery<\/a> on a Latitude 3450 configured with i5-5200U, 8GB DDR3L RAM, 256GB SSD, HD non-touch screen, Windows 10 Pro. Screen brightness set to 50%, Wi\u2011Fi enabled, standard room temperature.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Runtime Test Results (Brand New Certified TRHFF 58Wh Battery)<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Light office work (Word, Excel, web browsing): 4h 10min \u2013 4h 50min<\/li>\n\n\n\n<li>Video conference (Teams \/ Zoom): 2h 50min \u2013 3h 30min<\/li>\n\n\n\n<li>Local 1080p video playback: 4h 20min<\/li>\n\n\n\n<li>PDF reading &amp; document note-taking: 4h 30min<\/li>\n\n\n\n<li>Sleep standby: ~1\u20132% drain overnight<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">An aged original battery that only retains 30\u201340% capacity often lasts merely 40\u201360 minutes under light office workloads. Dell\u2019s long-hour marketing rating was captured under low-power lab conditions and cannot be achieved in real mixed daily use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What we like about certified<\/strong> <a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-3450-battery\"><strong>replacement dell latitude 3450 batteries<\/strong><\/a><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Accurate smart communication chip: Windows battery percentage, BIOS battery info and Dell SupportAssist health readings display correctly. No random percentage drops or \u201cbattery not recognised\u201d alerts.<\/li>\n\n\n\n<li>Stable discharge curve: No sudden hard shutdown at 10\u201320% remaining charge, a common defect of cheap generic batteries without qualified BMS protection.<\/li>\n\n\n\n<li>Exact OEM shape, mounting holes and connector: Direct drop-in fit after removing the bottom base cover, no cutting or modification required.<\/li>\n\n\n\n<li>Multi-layer safety protection: overcharge, over-discharge, short-circuit and over-temperature protection for safer daily use.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Weaknesses &amp; Important Caveats<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>No higher-capacity upgrade available. The Latitude 3450 (2015) chassis only fits TRHFF 58Wh.<\/li>\n\n\n\n<li>Critical compatibility warning: <strong>TRHFF for 2015 3450 \u2260 DR02P \/ R73TC \/ 2X1V9 for 2024 new 3450<\/strong>. They share the same model name but different connector and size, zero cross-compatibility. Many listings mix these two part numbers and cause returns. Always match the PN printed on your old battery label.<\/li>\n\n\n\n<li>Rated cycle life is approximately 300 full charge cycles under normal room temperature. After that, usable capacity will decline steadily.<\/li>\n\n\n\n<li>Installation requires removing the bottom base cover. Before touching internal parts, power off the laptop, unplug the 65W barrel charger, disconnect the battery cable and press the power button for 10 seconds to release residual static power. Do not bend, twist or puncture the lithium-ion cell.<\/li>\n\n\n\n<li>Swollen batteries are extremely dangerous. Stop using the laptop immediately if you spot bulging, warped bottom cover or lifted trackpad. Do not squeeze, pierce or attempt to charge a swollen battery. Dispose of it at a professional lithium battery recycling station.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-3450-replacement-battery.html\"><strong>Rechargeable dell latitude 13 3450 Battery<\/strong><\/a> <strong>Maintenance Tips<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use the original Dell 65W barrel AC adapter. Higher-wattage Dell barrel adapters work, but low-quality unbranded adapters may trigger slow charging or charging errors.<\/li>\n\n\n\n<li>Avoid draining the battery fully to 0% regularly. Deep discharge damages the protection board and shortens service life.<\/li>\n\n\n\n<li>If you keep the laptop docked and plugged in all day, use Dell Power Manager to set a charge limit (60\u201380%) to slow battery aging.<\/li>\n\n\n\n<li>Run battery diagnostics in SupportAssist or use powercfg \/batteryreport in Windows Command Prompt to track capacity degradation.<\/li>\n\n\n\n<li>Keep the laptop away from high heat, direct sunlight or soft beds while charging; heat is the biggest factor accelerating lithium-ion battery degradation.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>FAQ for<\/strong> <a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3450-battery.html\"><strong>Replacement Dell Latitude 3450 (2015) TRHFF Battery<\/strong><\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q1: Which<\/strong> <a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3450-battery.html\"><strong>battery part number fits Latitude 3450<\/strong><\/a> <strong>(2015)?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A:&nbsp; PN: <a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3450-battery.html\"><strong>TRHFF<\/strong><\/a> <strong>\/ 0TRHFF, 58Wh, 4-cell, 11.1V Li-ion<\/strong>.

There is no&nbsp; higher-capacity battery upgrade option.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q3: My<\/strong> <a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3450-battery.html\"><strong>Latitude 3450<\/strong><\/a> <strong>only runs when plugged in, Windows shows 100% battery. Is the battery dead?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: This is a classic failure symptom. First run Dell SupportAssist battery diagnostics and check battery data in BIOS. If the diagnostic marks the battery failed, replacement is needed. Rarely, this issue can also be caused by a loose battery connector or faulty charging circuit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q4: Can I replace the<\/strong> <a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-3450-battery\"><strong>latitude 3450 battery<\/strong><\/a> <strong>myself?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: It is internal and non-hot-swappable. You need to remove the base cover, disconnect the battery cable and remove fixing screws. If you lack electronics repair experience, hire a professional technician. Always power off and unplug the charger before disassembly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q5: Does<\/strong> <a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-3450-battery\"><strong>TRHFF<\/strong><\/a> <strong>support ExpressCharge?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Original OEM TRHFF supports ExpressCharge. Only certified replacement batteries with the correct smart communication chip support fast charging. Cheap generic batteries usually skip this function and charge slowly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q6: How do I check my battery health?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Two reliable ways:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Press F2 during boot to enter BIOS and open the Battery Information page.<\/li>\n\n\n\n<li>Open Command Prompt and run powercfg \/batteryreport, or launch SupportAssist to run the battery hardware scan.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q7: What charger should I use for Latitude 3450 (2015)?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Dell original 65W barrel-style AC adapter is recommended. USB\u2011C PD chargers are not native for this older model and may not charge reliably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q8: How many cycles can I expect from a new replacement battery?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Around 300 full charge cycles under normal office temperature. With light daily use and proper care, it can stay usable for roughly 2\u20133 years before capacity drops noticeably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q9: Is it safe to leave the laptop plugged in 24\/7?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Dell firmware stops charging once full. However, keeping the battery at 100% in warm conditions speeds up aging. If the laptop stays docked long-term, set a charge limit via Dell Power Manager whenever possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q10: What should I do if my<\/strong> <a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-3450-battery\"><strong>latitude 3450 battery<\/strong><\/a> <strong>is swollen?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A: Stop using the laptop right away. Disconnect the power adapter. Do not squeeze, puncture or force the battery out. Take it to a repair shop or authorised e-waste recycling centre for safe disposal.More info:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-3450-battery\">https:\/\/battery4pc.com\/product\/replacement-dell-Latitude-3450-battery<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.pc-battery.co.uk\/dell-latitude-3450-replacement-battery.html\">https:\/\/www.pc-battery.co.uk\/dell-latitude-3450-replacement-battery.html<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3450-battery.html\">https:\/\/www.pcsbattery.co.uk\/replacement-for-dell-latitude-3450-battery.html<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dell Latitude 13 3450 Battery Replacement Dell Latitude 13 3450 Battery Review &amp; Buyer Guide Important note: Latitude 3450 battery is a 14-inch business laptop, many sellers mistakenly title it \u201cLatitude 13 3450\u201d.
