Proper manage new battery

Question

Hello everybody,

I am going to install a new battery on Dell G5 5590, the new battery should be already pre-charged. Does anyone have some suggestion on how to properly manage a new battery? I know that there are a lots of hoaxes on the topic, so I was wandering what is the "real" way:

- shall I first discharge completely the battery and then make a "long first recharge" (e.g. half day) ?

- shall I first discharge completely the battery and then make a normal recharge ?

- shall I don't care about discharging the battery, just install it and work with the charger attached as I normally do?

- other ways ?

Thank you in advance for your replies.

I also would like to spent 2 words about Dell Hardware "Premium" warranty: it doesn't cover the battery replacement, since battery is considered a consumable item. This is not clearly stated in evidence on the recap of what the warranty covers, it is just mentioned in a tiny article in the contract. I think this is a lack of transparency, and I am unpleasantly surprised that even a company like Dell uses these kind of tricks with their customers. Just for the community to be aware.

The answers to your questions are no, no and yes. Never discharge a lithium battery completely or nearly so.

Just charge it and use it normally.

It IS a good idea to charge it to a set percentage (70% works) and have the charge cut off after that -- in other words, it should not be run on AC power, constantly charging to 100%.

As for the rest, it's standard in the industry to warrant batteries for one year, regardless of any extended system warranty. On some business systems, a separate 3-year battery warranty can be purchased.

Hello @ejn63 ,

thanks for your answer. I didn't know it was possible to cut the charge after a certain percentage, is it a BIOS setting?

In this case I should let the battery discharge down to 50% (let's say) and then work normally, on AC power, and battery will charge up to 70% and remain like this. Is that correct?

I have purchased a new battery, activated the upper charge limit to 70% and currently I am testing it. So far so good.

Yes.  You should have that option in your Dell Power Manager software.
