It does what you expect










--Genuine Dell part--
1 I compared the labelling of my original Dell battery with this one and they match.
2 The battery has several screw-in points and they are all exactly the same as the original. I had previously seen customer reviews of copycat 33YDH batteries that have found differences in this respect.
3 I compared the "Battery report" [PowerCfg -BatteryReport] & "Energy report" [PowerCfg -Energy] for this battery with those for my original battery. The Battery ID & Name parameters are as expected. Its Design Capacity entry is as expected, 55997 [mWh]. I have seen copycat batteries for other computers in which these factors differ.
4 My bundled Dell utility "Dell Power Manager Lite" says it is a Dell battery
So I conclude that this is a Genuine Dell battery that will last well [its nominal life should be 300 charge/discharge cycles as it gradually degrades from its current charging level of 55997mWh].
--Charges properly--
1 It arrived at about 20% charge.
2 It took a quite sensible 2 hours to reach full charge.
3 After this full charge, I ran the reports again and it had, as I expected, charged up to the full Design capacity, 55997 [mWh].
--"Fulfilled by Amazon"--
1 I already know that Amazon fulfils the responsibilities of a retailer properly when it comes to "fulfilled by Amazon" items.
So everything looks good. I've been searching for a genuine Dell battery for two years and I'm really pleased to have found one at last.
My original battery now only charges up to about 38000mWh [a quite decent level of degradation after two years]. I intend to take the back off the computer every other month to swap the batteries over in order to even out the wear n tear. I also have a 'Dell power companion' [external battery] [https://www.amazon.co.uk/Dell-Companion-PW7015L-External-Inspiron/dp/B00XPUEE4K] that reduces demands on these critical internal ones. With any luck, this set of batteries will last until the computer is at least six years old.

Anyway, this battery arrived with about 20% charge. 12 screws on the case (PZ1 or perhaps PH1) , gently lever open with a small flat head screw driver. The battery is screwed down with six screws (from memory) - again PZ/PH1. There is a single connector to the motherboard. Connect that before screwing the unit down because it is easier. make sure it is fully home.
The laptop accepts it as real (this one claims to be manufactured by Samsung) and it charges correctly and gives a decent lifetime.

So far I am cautiously very happy. I've gone for five stars across the board because it does last pretty well - this is a power guzzling laptop i7, 8 threads and I run an OpenGL window manager and quite a lot of background stuff.

Problem 2: Amazon's returns process fails to mention that lithium-ion batteries are classified as hazardous, so will not be accepted for return by post offices, nor most parcel carriers. After 3 hours trying to find a carrier, I came to the conclusion that Amazon needs to notify returns customers of appropriate transit arrangements with nominated carriers.
