You should log in to the dell.com website go to the support page & enter the serial # of your machine. From there you will be able to retrieve a list of components or a spec sheet....that will lead you to the correct CMOS battery. I did that & I am very pleased with the battery replacement I purchased. My machine is NOT an E5420. Good luck. **Q: Does this battery fit a Dell M3800 Precision laptop?** A: I appears from descriptions that the CMOS battery which fits Dell Latitude E6420 also fits Precision M3800. A search for it should show pictures & description should give number of pins & voltage. **Q: Will this fit a a 2014 dell e6400 latitude? is it the correct connector?** A: Yes,it fits for E6400 all year models. **Q: Is this cmos battery ok for a dell precision m6300 ?** A: This is a three wire battery - generally for older systems. Physically check the motherboard in the M6300 to see how many wires its battery has. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install. Worked as advertised. Review YouTube Replacement Video(s. ESD Care Required *by R***N on June 1, 2019* After watching a couple of YouTube "how to" videos -- replacement of CMOS battery was straight forward. Required phillips "jeweler" screw driver & find needle nose pliers. Please DO USE protections and good work bench habits to prevent ElectroStatic Discharge (ESD) damages to laptop motherboard & components (see wiki pages for ESD hazards). BIOS restart? When the old CMOS battery went dead, the Dell e6420 lost key BIOS settings -- especially for NVIDIA card use vs default video display handling by operating system. Graphics intensive & GL dependent apps (like Google Earth) will be "broken" until the BIOS is reconfigured to hint & encourage Operating Sytem to "defer" to NVIDIA "display adapter" for screen renderings. Good time to vacuum laptop mother board and clean CPU cooling fans / grills from accumulated dust, lint & dirt. Use rigorous ESD protections w/ vacuum system -- vacuum systems can generate TREMENDOUS ESD hazards. ### ⭐⭐⭐⭐⭐ Good direct replacement for my use. *by R***H on April 16, 2024* Fixed my laptop, installation required some work to install. Overall quick shipment of what I needed. ### ⭐⭐⭐⭐⭐ Perfect fit for my older Dell Latitude 4750 *by S***B on September 3, 2025* Perfect fit for my older Dell Latitude 4750 ## Frequently Bought Together - Replacement CMOS Battery for DELL Latitude E6510 E6410 E6500 E6400 E5510 E5500 E5410 E5400 Backup Reserve RTC Batteries 3 Pins 3 Wires - Fancy Buying New Laptop Battery for Dell Latitude E6400 E6410 E6500 E6510 Precision M2400 M4400 M4500 M6500 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/69625495-replacement-cmos-battery-for-dell-latitude-e6510-e6410-e6500-e6400](https://www.desertcart.co.uk/products/69625495-replacement-cmos-battery-for-dell-latitude-e6510-e6410-e6500-e6400) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-22*
