Ideas to drain battery?

[jmunk]

I was thinking I don't like vaping on a low powered battery so I tent to charge them before they are completely dead. I think get about purchasing a flashlight to drain the battery to ensure proper draining before charging. Am I over thinking this or do you think the would be a good idea?

Why do you Want to Drain your batteries before Recharging?

What kind of Batteries are you Using.... Ni-Cad's?

lithium ion batteries do not develop a memory like the ni-cads of 20 years ago. You can "top off" the battery anytime you wish.

X-Zactly.

In Fact, Most People Recommend that you DO NOT drain a Li-Ion based Battery down all the way before Charging.

Here is some Good Info on All Things Batteries.

Basic to Advanced Battery Information from Battery University

No.

Different kind of battery.

These should not be allowed to drop below 3 volts.

When you see something like "this battery will do 300 recharges" it means 300 full cycles not sticking it in the charger 300 times. If you recharge when the battery gets half way down you should be able to do that 600 times, Use only 10% before recharge then 3000 recharges. About.

You have already had you question answered but I just wanted to welcome you to ecf. There are always folks here that can help ya. That is what makes ecf so very special. Good luck to you and happy vaping.

Do NOT drain a Li-Ion battery until dead! These are more like your Lead Acid batteries in that charging them often and keeping them charged results in the best life. The deeper you drain them, the less life you will get. Most Li-Ions even come with a warning to not let them discharge below a certain voltage and to NEVER let them sit in storage with out a full charge first.

You never want to drain a battery all the way down, you can damage cells this way, when it starts to deplete and you notice it isn't working as well as it could on a full charge put it back on the charger, NEVER drain the battery.

Just to add that's the reason most electronic mods will shut down at ~3.2V. In fact most chargers won't accept batteries discharged below a certain level.

Good to know... Thank you all for your input, I guess there's no need for a cool flashlight anymore :-(

Get one anyway that uses the same batts that your mods use. In an emergency you can always use one of your 3.7v batts.

Huh? There's ALWAYS a reason to get a cool flashlight.

Just like vape gear.. Always a good reason to get a cool flashlight.. cause it's There!!
I have several 850LM lights and just got a 1000LM zoomable flashlight .. all using the same batteries!

Actually you do NOT want to store your batteries fully charged. That will shorten the life. If you expect batteries to not be used for an extended period of time they should be stored at (about) 3.7 volts.

When the batteries are shipped brand new to you they are normally at a "storage" charge. You need to charge before first use. This is not because manufacturers are lazy, it is because it will extend the life of the batteries prior to being sold.

The very high end lithium battery charges have a function that will charge the battery to 3.7 volts and stop. This type of thing is common is radio control airplane/helicopter industry. It is commonplace to not use the batteries the entire winter (in the north, anyway) and storing your expensive batteries at a "storage" charge is necessary. It is not unusual to spend well over $100 for a single battery and most people wish to protect their investment.

No need for cool flashlights .... blasphemy

For all intents anD purposes 'storing' in this case means 'for a few days to a couple of weeks' ie: until the next battery is drained ... You are correct in that if you are going to want to store the batteries for longer than that, then the 40-50% SoC would apply.

So when you purchase a new battery should you use it to drain it a little and then charge... Or throw it on the charger right away?

I charge mine when I get them.
There is no need to drain a lithium battery to max discharge. They are not prone to memory effect. You actually gain lifespan by using shallow charge/discharge cycles. Much like a lead acid battery, Li-ion batteries do not like deep discharge cycles and should not be stored in a state of full discharge.
As has been stated;
For short term storage (a few weeks) fully charged is fine. If you are not going to use them for months, storing batteries at 40 to 50% charge is best for the battery.
