What does this mean?

I just bought a rechargeable head lamp.

While reading the instructions, I came across this sentence:

Please do not recharge after running out of electricity for a longer using.

I'm usually pretty good at interpreting mangled English, but this one has me stumped.

Any ideas?


Don't let the battery discharge fully before recharging? 


I agree with Joan with the following addition: "To prolong battery life [instead of "for longer using"], don't let the battery discharge fully before recharging."


Bad command of the English language, if you ask me.  I think the message was to recharge after use, BEFORE you run out of electricity again and can't do it.  If you try to charge it AFTER you run out of electricity, you are SOL.  


OK, but none of those make any sense. I've never heard of a rechargeable battery that you can't charge if it becomes totally discharged. Is that a thing?  What do I do then, throw it away?

It sounds to me like the more deep discharges you allow, the shorter the lifespan of the battery overall. You'll notice the battery doesn't last as long after charging. Eventually it will be not worth it to even charge any more.

Then throw it away. This is America where everything is disposable.


I thought that was true with older battery technology, but not with newer stuff.

Who knows.

 You can, but it impairs the battery life somewhat, so better to recharge while it still has some charge left.

i.e. what kthnry said.


In days of yore (yeah, I used that expression) they used to say that it was a problem to let your phone fully charge plugged in overnight. Someone recently told me this was in fact not true anymore, and it was no such thing as 'overcharging'.  That being said, I have a rechargeable flashlight that dies all the time, several electric razors that do the same thing.  Eventually, they don't hold the charge as long and then drain that same charge faster.  I'm with the incredible one on this - you will eventually just have to replace, as it will charge until it doesn't.  


I've been through discussions re:batteries on many photo websites.  There's little to no controversy about battery use.  So, rather than try to decipher "mangled English" I'll try to give the best advice I've found.

Many rechargeable batteries still ship PARTIALLY charged.  It's- 

*IMPORTANT* to make sure the battery is fully charged before first use. 

When to recharge:  Almost every mfr. has said specifically to continue using a battery until it is low NOT depleted.  Then fully recharge.  Many togs like to 'top up' their batteries before setting out for the day.  Panasonic-who manufactures batteries- says that frequent topping up will lead to swelling.  

So, many togs of try to follow this practice.  Most cameras have an on-screen indicator (mine is the usual 3 bars).  When charge life goes from 2 bars to 1, get your next battery handy.  Change as soon as convenient so as to not miss a good op.

Finally, the reason why there's debate about batteries is which mfr's products to use.  That is a whose not how question.  OEM replacement for my Panny G6- MSRP $55.  Wasabi (highly respected)  ~$15 purchased directly from Wasabi.  


Wait, can I go back to the original poster for a sec - you did say you bought a head lamp, right? One of those things you wear on your head at night to see in the dark when you are out there for whatever reason? You have a USB chord to charge it directly when it's low? There is no actual battery that you take out of that little thing, correct?  I'm no expert, but I don't think there is much point to worrying about how much battery is left when it goes.  At that point, you be in the dark.  Funny how this thread became about the merits and functionality of rechargeable batteries in way bigger things.  


It was Agatha all along.....


Actually I'm on your side. I dislike rechargeable batteries in anything light related, but I couldn't find an acceptable one that wasn't rechargeable.

 I could have made this whole thread about bad English that really pisses me off, hence my Agatha reference. I can't help cross posting.   Good luck going out in the dark.  


Yay! That is SO what I thought.  


I actually bought it so I could see way back into my mouth to my extracted wisdom tooth while looking in the mirror. (see the Dry Socket thread)


DB: You may want something like this Otoscope - it's a short focal length camera with a light. It's designed for DIY ear wax removal, but it might work for your viewing needs if it can get the correct angle. Easy to use with a PC - just plug into USB port and use the Camera app to see the image on your screen.

 Just make sure your computer is not connected to the net when you're using it .. you never know who might be watching!     grrr   (Cue those scam emails that suggest that 'someone' has got into your computer and recorded you watching naughty stuff etc etc)

 I've already got a similar device that's more appropriate for the mouth. But in this case I need the light to guide me while I apply medication to the tooth.

 No, really? Thanks for the cross post.  It's like a scavenger hunt now....

 Layer within a layer - All I can say is - EW.  Remind me to tell you the story of my detached retina one day, that was just as fun, but not quite as painful.  Thanks also for the Marathon Man flashback - such an amazing film.
