Thread: Best recharging treatment for Li-Ion batteries?

I use the try not to let them drop below 30% and then charge them up.
I thought the idea of not charging them above 80% is for long term storage.
If you are going to use them regularly there's no real problem with charging to 100%

Do you think it matters if the charging is interrupted? E.g. charging is started, get a phone call - easier to talk without cables and powerbanks in the way - recommence charging after the call.

No I don't think interrupted charging really matters much.

My protool drill and impact driver I bought in 2005, at the time they were expensive because of the “new lithium ion technology “, 17 years later, they still run like new and I’ve replaced one battery because one fell in the river. Both drills have also been underwater in a flood. They pull the pants off all other drills that guys bring to site too, best investment ever. I just charge them when they go beep to say they are flat.

Electronics manufacturers already exclude you from using the maximum technical capacity of the battery to ensure they have a reasonable lifespan (beyond the minimum of their warranty). So the 0% to 100% range you see on your iPhone is really only going from 20% to 90% of what the battery could do. This helps save the battery and stops users damaging them too badly.

It is mainly the deep discharging of the battery that impacts their life so you can help battery lifespan by not draining your battery or going into the bottom 30% too often. Don't worry about overcharging as the electronics already stop it from being charged too much.

Yep, Yep and Yep.

I am terrible with my iPhone and often let it effectively turn itself off because it has run out of charge. Typically I forget to set the sleep time and I fall sleep with music or and audio book running and it will turn itself off. I did the same with the iPhone i had between 2010 and 2016 and with the more recent one which I have had since 2016. Sure, the battery longevity performance is not what it was when it was new but its still pretty good for a 5 year old phone.

Bring back replaceable batteries I say. Hmmph. I got ten years out of my Nokia 6110, with 4-5 new batteries ($4.50 each inc post from Hong Kong).

There are a few generalizations that can be applied, courtesy mainly of the drone manufacturers were battery life is paramount.

Don't charge to 100% then leave the batteries to sit for weeks at a time. My drone battery packs actively discharge to 50% after a set period of non use.
Don't leave them dead flat, though with active battery management dead flat is still likely to have cell charge... you just cant use it.
Charge them to 100% before use if possible.

Apple did introduce some active battery charging metrics based on usage patterns and i've seen it halt charging at 80% and then charge to 100% later

For nearly every practical purpose in electronics just charge and use, LI in general doesn't have memory effects.

For tools etc, daily use as above... weekend, random use then treat them with the 50-80% rule.

anyway that's my 2c, 2.2 with GST worth

So your turnover is >$75k per year then eh?

I use a house fan and a timer that plugs into a wall outlet to reduce over heating my tool batteries.
When the battery is at 50 - 60% put it on the charger and keep watch on it until it reaches 100%
Now set the timer for charging that duration in the future.
I fully charge them when they drain down to 50 - 60%
I sometimes accidentally let a battery fully discharge unexpectedly and recharge it immediately.
No noticeable battery damage or performance issues.
This website is great.

For batteries, I use the NiteCore UM4 charger. Its the bees knees.

On phones, swapping a battery out isn't too challenging. Done it many times.


My experience is only anecdotal, but I've always only charged my devices infrequently, even the phone.

I let it drain down a fair bit before popping it back on the charge and I absolutely DO NOT do it every day.

SWMBO seems to need a new battery every 2 years (that's IF she hasn't smashed the damned thing, again). I have never replaced a battery in any of my phones, ever.


On a slightly different tangent, we've a NiCD B&D dustbuster hand vac that has started to misbehave. It is used all the time and was bought around 2004.... its time to buy some Sub-C's and solder/swap the old ones out


What DOES irritate me, is there is no means of recycling batteries. We need a solution, such as dropping them off at the servo into a hopper.

My local council takes batteries (all sorts I'm pretty sure) at the dump. Might be worth checking if there's a similar service near you. Not sure where the council sends them though...

Battery World accepts all old batteries.
Officeworks accepts batteries, computers, electronic equipment.
Also local councils at libraries.

Office works accepts the following batteries

We accept domestic single use or rechargeable batteries in the following sizes:
• AA, AAA, C, D, 9V
• Laptop batteries
• Mobile phone batteries

*We don’t accept industrial or commercial grade batteries, such as machinery batteries.

So no vehicle lead-acid batteries, also 6V lantern battery are not listed - I suspect they will take them

Our local council waste transfer station will take all of the above plus 6V lantern and lead-acid vehicle batteries

Our local council front office will accept "non-rechargeable household batteries" whatever that means.
