Worked for my Dell 5420, says 100% battery life
Worked for my Dell Latitude 5420. I’m unsure of my specific model of 5420, but it’s the 14” with no smart card reader slot, and no tap card reader. Specs are in the pics, I upgraded the ram to 32gb, stock was 16gb. I bought this battery to replace an aging stock Dell RJ40G, which showed up as model 1K2CF19 in system info. Took me about five minutes to swap it out and boot back up. In Fedora 43 with KDE Plasma 6.5.2 the new battery shows 100% health and at 61% capacity says it has about 6 hours to discharge. That’s over twice as long as the battery I replaced that had 52-55% health. I know others have said it didn’t work for their 5420, so still caveat emptor, but it worked in mine. So far it’s good, I’ll update my review if I encounter anything in the next few weeks.

    I got this to replace a battery that had less than 70% charge in it.

    The replacement process was straightforward and didn't require any instructions, thankfully. If you've ever opened a laptop before and replaced a component (HDD, SSD, RAM, etc.) this was only slightly more challenging. Dell made the process as easy as they could while allowing the laptop to retain a decent size. If you do not have much experience opening laptops and replacing components, using this replacement battery to replace your defective battery may be a bit challenging and you should seek assistance, in my opinion.

    I was very glad to have the tools included even though I did not need them, but had this laptop never been opened before, the plastic pick included would have been so greatly needed to ensure the chassis is not damaged by metal tools. I did not use these tools during this process as I have my own and my laptop had been opened before, but greatly to have them included with the replacement battery.

    After installing the replacement battery and closing up the laptop chassis and then turning on the laptop, it did take a moment for my OS to notice the new battery. The laptop would not boot without being connected to power and once in the OS, the battery indicated 29% charge and did not move from there for several minutes. After a few minutes, the battery began showing 11% and then climbed to 57% before I turned off the laptop. Checking the health of this laptop in my OS, my laptop reports this has a 98% health rating which is still decent for a replacement battery like this.

    Excellent product for the price. Definitely glad I bought a battery which included screwdrivers and spudger (looks like a guitar pick). Watched a youtube video for instructions on installation. Everything went surprisingly well. Would definitely recommend.

    This battery fit well, however, It only lasted 6 months and will not charge or be recognized by the laptop. Tried all recommended trouble shooting steps to no avail. Even replaced the charger. It was months beyond the return period so I direct messaged the seller. They responded in less than 1 day. Offered to replace battery free of charge without having to return the old one. What amazing customer service. Would use this seller again definitely!

    I dont know what is going on but so far this year everything I've bought through amazon has been subpar. this battery barely last 3 hours let alone 4 on a full charge and then it just shuts-off with no warning. I am glad I kept my old battery because at last there I get a warning before it shuts off.
