Want to control battery charging

Try3 said:

Mine is what my computer came with five years ago. I have never found a download link for it [there isn't one in my Drivers & downloads section].

I don't think your Power manager lite can set a % charge. The Advanced charging you are working with does not have that capability.

I do not think that your efforts are going to achieve anything tangible anyway.

Do you (or anyone else reading this) know where the later version (version 1.0.7) can be downloaded from? It would just make me feel more in control of my battery charging if I could try out this later version.

For my Dell Inspiron 7779, Dell power manager lite v1.0.7 is a component of Dell Quickset which is available in my Drivers & downloads section.
Dell QuickSet Application - Dell support
I suggest that you use your Dell Service tag to go to your own Dell support, Drivers & downloads section then re-install your own Quickset to see if doing so gets you the utility that will not achieve anything for you anyway.

All the best,

Thanks for those links!
Well, after clicking the links and seeing what driver downloads are available for my computer, there is only 1 with the name of Dell Power Manager, and it's the same one as I've got, and was released in November of 2015. I'm getting the idea that the more recent version that you have is not showing up for me because your computer is newer and is compatible with a newer version of that app, while mine is not, so it only shows me the older version.

Looking through the drivers for your computer, I found the Dell Quickset application which was released in June of 2017. I'm thinking I probably shouldn't download it to mine because it's made for your computer which is a 2 in 1 while mine is a standard laptop. It might mess things up on mine since the driver set would contain things foreign to my computer. It would be nice if they'd just have the later version of the battery manager available. Oddly, I'm not even finding any 3rd party apps that do the job. Grrrrr!

I would not want to encourage you to spend too long on this because there is no publicly available test data that supports the idea that partial charges extend the life of a battery.

BU-808: How to Prolong Lithium-based Batteries - Battery University

It is absolutely 100% for sure a known fact that leaving Lithium Ion batteries in a fully charged state (4.2V) will lower their overall usable lifespan. These batteries simply don't store well long term fully charged. Manufacturers that I know of for sure that address this:

Apple - Apple now has the ability to delay the full charge of iPhone batteries to a full charge until just before your wake up time to make the time spent at full charge less.

DJI - DJI drone batteries will automatically self discharge battery packs for their drones to a certain level if the pack is not used within 24 hours after a full charge. This is done specifically to increase the lifespan of the battery pack.

XTAR - XTAR makes battery chargers that have a "storage" function designed to charge or discharge Lithium Ion batteries to a voltage of 3.7V rather than a full 4.2V for long term storage.

ISDT - Like XTAR, ISDT has battery chargers that provide this same capability.

Dell has some laptops that specifically support custom charge levels to avoid long term storage at full charge.

Sony also had similar support back when they sold their VAIO laptops.

I'm sure that there are others, these are simply the ones that I have drect knowledge of.

You will also find that the makers of some Li-Ion batteries themselves specifically suggest long term storage of between 40% to 60% charge level, with a recharge to those levels every 12 months.

Frankly, it's easy to go overboard on this topic. I typically find that batteries such as laptop batteries that are left fully charged for extended times will still last several years, but let's face it - a battery is a consumable that must at some point be replaced.

And exactly what evidence do you think is in that article? Please be specific.

Denis

Any and all of the related tech literature that's based on hard data from numerous experts worldwide plainly contradicts your earlier statement of the impact of charging level and depth of discharge on cycle life being negligible/nonexistent. So, I had decided to just post a link to an article that correctly explains it in the simplest of terms─put it any simpler than that and it just boils down to the common observation of Dell trying to be mischievous again with more of their same old and worn out marketing BS.

Follow-up:

Here is just one of many spec sheets I was used to working with as an Engineer that makes specific long term storage recommendations.

Note that section 11 on this topic specifically recommends not storing the batteries fully charged:

"Our shipping voltage is 3.75-3.80v . because storage at higher voltage may cause loss of characteristics."
