How to preserve mp3player battery life?


Recommended Posts

I can't find a suitable forum to post so I just choose this one.

I'm using a Creative MuVo Slim Mp3 Player and it uses a Lithium-ion rechargeable battery. I am concern about the life-span of the battery since it is not user-replaceable and requires to be sent down to Creative should it fails.

Firstly, how often should I recharge the battery? Should I recharge the battery after it has been completely drained or charge it irregardless of the time of usage?

Please advise, thanks.

i would guess hardware forum but im just new

those batterys are pretty good and usually last around 1000 charges , also u can replace battery , but u will have to send it off to be done .

Remember when u get a new rechargeable device before u even trun it on make sure u charge battery for over

12 hours , u will get a extra 3 years outta them :).

I only did the "first ever charge" for about 3 hours only cause it's stated in the manual. I hope it's not going to affect the battery much. Anyway, should I charge the battery after it is completely drained or charge it whenever after usage?

Creative Zen recommends not to use mp3's over 128bit for power saving. Also do a full recharge and time battery life, Next time u use it stop before its due 2 die and pop on recharge. Zen also warns of low battery and stop use so it never dies. Maybe this will help.

:o)

My dad has always told me you should run batteries all the way down till they are totally dead before changing them up fully, im not sure how true that is.

I know for the ipod they tell you to not drain the battery since it's always running and reading off the hard drive even whem sleeping. I don't believe the muvo is hd based? but i'm not sure. Prolly just run it down to when it's nearly drained and then just recharge.

Lithium-ion i think prefer to be charged any time, dont think they like running really low then charging, so keep it topped up

Ni-Cad, Ni-MH these have memories so to prolong its life, fully discharge these before recharging.

Google will be your friend if you use it.

:huh: I woulds get 2 batteries -- keep one charged up -- let the one in use run down completely.

from the first post:

lithium ion batteries should *NOT* be fully discharged. it does not have a memory effect. if you discharge it then the battery life will shorten quicker.

Quoted from http://www.batteryuniversity.com/parttwo-34.htm:

A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges.

Simple Guidelines

* Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.)

Short battery life in a laptop is mainly caused by heat rather than charge/discharge patterns.

* Although memory-free, apply a deliberate full discharge once every 30 charges to calibrate batteries with fuel gauge. Running down the battery in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate. The battery life will not be affected.

* Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.

* Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)

* Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing date. Do not buy old stock, even if sold at clearance prices.

OK, thanks everyone, I've the answer now. So to anyone who is concerned about the Li-ion battery life too, read the words in bold.

Once again, thanks for the replies everyone! :)

I lasts about 18 months according to a video at http://www.ipodsdirtysecret.com . When the battery fails, you've to send it to Apple to get a replacement battery for US$99.

and you're a moron if you believe that video. sure, it happens. but certainly not as often as they'd like you to believe. i have a 2g 10gb ipod (gotta be at least 2 years old...) and the battery still gives me the same power it did when i got it.

those guys probably missed all the tips on how to preserve the battery ;)
