What is a good battery replacement for the stock battery in Fiio E11? - Page 2

post #16 of 45

Is this battery as good as the original/IEM/Nokia one?

I used it every day since I got it.



1.) FYI, I never turn off my e11. it's either on because I'm listening to it or it's on while it's recharging. Should I turn it off when it's recharging? And my e11 usage is high mode, low gain, boost level 2. How many battery hours would that allow per session?


2.) Further, every day I take a couple of breaks, during which i recharge it in the E11 by plugging in the usb charge cable. normally the charge would finish before i get back since i haven't used it long enough. S
ometimes though it's still recharging it when i get back -- should i let it finish recharge or can i interrupt the charge to resume usage? and is there anything important i should know if after I interrupt the charge?


3.) And every night I fully charge it (the red light is off by the next day.) At this point, should I unplug the charger cable and the e11? I have the e11 turned on 24/7 since i can't be bothered to switch it on/off and go back to my normal listening volume every time I use it.

I believe the stock battery actually comes with warranty. You might want to check with the seller to see if you can claim it or not.

E11 should turn itself off when recharging, but that's beside the point - you should turn it off from time to time, as 'deep cycling' (which is basically what you were doing) is bad for battery life in general. But even so, the battery should easily last more than a month. There might be something there. Anyway, you don't have to recharge it too often. Unless you really do drain it out completely before the end of everyday, my advise is to only charge it once per day. In normal use, you can expect E11 to run over 10 hours in high power mode.

Unless someone have bought the same battery from the same user and tested it, no one really could tell you how good / bad it is.

so after the first few 'cycles,' during normal usage i should turn it off when i'm not using it and recharge every 2-3 days and then 'cycle' it once a month?

 

by 'cycle' do you mean to use it out (over multiple sessions) w/o recharging it yet turning it off when not in use between teh sessions and finally recharge it after it drains?

if you are using it almost 10 hours a day, then you should recharge it afterward, perhaps over night.

if you are using it only 5 hours a day, then you should recharge it every 2 days, but every night is fine just as well.

If you are using it 1~3 hours a day, then recharging it every 2 or 3 days is fine, so is every nigh.

The key is not to run the battery to completely flat. If you can't be sure, just turn it off and recharge it every night (heavy use) or two (light use).

A cycle generally refer to running the battery from full charge to relatively low level (i.e. 10%~30%). A deep cycle means it is run from full to empty . A deep cycle is generally something to avoid, so is not running cycle at all (keep recharging even it is 96% or so all the time). That is, you don't want any of the extreme.

Then what does it using it out mean? To use it until the battery  runs out then fully recharge it?

 

if that is the case, I can use a timer to time how long the battery will last per session. i can use the timer to gauge when I approach the 10-30% threshold...

You can do that, since you don't have a volt meter.

I got them (bought four for $10 shipped).  So far all I can say is they got here and charged.  They work in the E11.  I rarely use my E11 for more than 4-5 hours without charging the battery.  I'll only use this new one though for a bit and report if it's any different.  At least it was cheap, arrived, looks legit, and took a charge.

I don't have one unfortunately.

There is a digital multimeter model DT830, usually sells and ships for around $5-$8, eBay.

Only $4 from China.

do I need a volt meter at this point? and how and when do I use it to monitor the volt level? don't tell me i gotta take out the battery every day to measure it..how many hours does this battery last?

 

edit: well i guess if i forget to trigger the timer i woudl need a volt meter to be safe and measure it...

 

wuld this one do the job?

1) Yes. When the red light is off, the battery is fully charged.
2) You can charge it right away, then use it out. The point is to 'cycle' the battery capacity, how you do it is less important.
3) You can repeat it one or twice, then it should be fine.
4) You don't have to, but it is usually considered better to recharge Li-ion as often as you can. But once in a while (say every month or two), you will want to cycle the battery to keep it in an healthier state.


I just got the battery in the mail today! Woohoo!

 

It says "2012.02" on the hologram sticker. I wonder if that means the date it was manufactured?

 

As for charging the battery, is it possible to overcharge it with the e11's USB charger cable coming from the mini USB charger outlet adapter?

 

Is it better to recharge as often as I can when I'm not using it while it's still on or when I'm not using it while it's off? Aside from the cycling, I plan to discharge the battery's capacity down to 20% (i.e. if a full discharge lasts 20 hours I will discharge it until 16 hours) and then turn it off and only then I will finally fully charge.

 

I'm afraid if I fully charge it every time I turn it off it may reduce the battery's capacity. Likewise, I'm worried if I charge it over night or forget to unplug the USB charge cable immediately after the red light goes off then it will overcharge and damage the battery.

 

Thanks

Yeah, it probably is when it was manufactured.

 

You shouldn't be able to overcharge E11's battery since it has an internal protection circuit to stop you from doing that.

The battery is fully charged in a few hours, at least it appears that way. The red light is off. Should I wait for several more hours or am I good to go?

post #28 of 45

You are good to go. It will likely take another cycle or two for the battery to reach 100%, but there is no reason why you can't use it now.

Great! So far it's just 3 hours in. I'll keep ya updated on how many hours it fully discharges for the first 2 or 3 cycles. How many hours is it suppose to last at 100%?

I jsut cycled it once. that discharge session lasted around 15 hours or more....now i just fully discharged it again at 10 hours! WTH it lasts just as long as the old battery so is it defective ?...lol i just told the seller a few days ago i was gong to test for any defects well there we have it...it's gonna cost a heluva lot mroe than the product itself to send it back...ugh
