T0TRM Laptop Battery Replacement for Dell XPS 15 9530 Precision M3800 Battery TOTRM H76MV 7D1WJ 11.1V 61Wh Battery

The good stuff that I can say is that the battery came quickly and fit my Dell M3800. However, that is where it ends. I mean, it works and all, but this thing doesn’t hold even 20% of the charge that the OEM battery did. Yes, I followed the instructions and ran through 2 complete charge/discharge cycles. I even did a third one when the battery died too quickly. That hasn’t helped and the battery only seems to last about 45 min. That sucks for any new battery, but this thing used to have a solid 4-5 HOURS when I first got it. So yeah, the reviews complaining about battery life are true. I thought it was because people weren’t following the instructions, but I know I did and didn’t get good results. You are better off avoiding the cheap junk in this site and buying an OEM from Dell. AVOID!!!!

First off, this is for the Dell M3800. I bought this battery for the price. I knew mine was bad (wouldn’t hold a charge and it was swelling) and I wanted the replacement quickly. This battery is fairly close to the original Dell battery. When I was installing the battery I noticed two slight issues. The screw holes didn’t quite align with the posts (first photo). I needed to start one alignment pin and slowly kind of pull the battery over to match the other post. You can see in the second photo that the holes still aren’t perfect but I was able to get the screw started squarely. The second time of note is the battery connection. The orientation of the harness and connector coming out of the battery pack make it tricky to hook up. I had to connect mine first, prior to putting in any screws, in order to make the connection and harness lay properly. You can see how tight it is in the third photo. Overall, I’m happy with the battery.

reasonable price, especially it comes with tools to install.

Easy to install and battery life is great!

Battery came with a set of tools needed, making installation quick and easy. Appears to be good quality and has performed perfectly so far. Appropriately packaged and shipped quickly.Unfortunately, the seller seems a little questionable. The box included one of those "write a review and get a gift card" flyers that are becoming so common and I figured why not. But the response I got asked for my order ID (reasonable) and PayPal ID (unreasonable). While I'm happy to provide my honest feedback, I am not willing to give away my personal info for the offer of $20.

My new battery does NOT work. As it required more than 1 month to install and figure this out, Amazon will not help. Furthermore, after numerous clicks and web searches, the manufacturer cannot be found. Although a 12 month replacement is promised, and manufacturer says to contact them, there is no way to do that, including in the "manual" packaged with the product. Let the buyer beware. Seems I'm stuck unless they somehow contact me here? Also:Used in a Dell M3800You can't find this batt at Dell unless you call"Manual" is translated, cryptic, and difficult to follow and understand.Instructions/rules for readying the battery for first time use are abnormal and complex. You will need more than 30 days to complete that, if you can even understand the English.In short, terrible product, I'm stuck, need a Vanpir replacement, and have already gone to Dell to get a refurb.Oh, and, obviously, there was no $20 in my box to leave a good review. Those who did, did indeed create a critical mass that fooled me.

Great battery for a customers Dell Precision M3800! Unlike other generic batteries - this one did not appear as third party and displayed no warning messages in bios. cable was more than long enough and the free tools were much appreciated!

Followed the included installation instructions, discharged down to 7%, recharged to 100 and repeat 3 or 4 times. So far it is working great!
