What battery to buy, Where to buy it?

[idivorceyou]

I am on my 3rd replacement battery. This time I went with the Newertech. my last one was a Cameron Sino purchased off ebay, the first replacement was a no-name. Let's hope the third battery is the charm. The prior 2 replacements started off great, and my Cameron Sino gave me over 24 hours on my first test out of the box (constant play of "random all" until player died).

The replacement this go-round was a snap - having done it twice previously, the entire process took less than half an hour. Tweezers are key!

somewhere above someone mentioned the ipods99 iriver ready battery, but that is a 1700 mah battery, and is $29.95 - no bargain there and if you are going to open up your player, why not add 5+ hours of playing time by getting a 2200 mah ipod 1g/2g battery and simply switching the wires? It really is easy.

If you are on your 3rd replacement, there is something wrong somewhere
There have been reports that it may be board not the battery sometimes
Are you leaving your ac adapter attached after the battery is full and your not using it?

Any reccomendations for an h10 20 gig?

How long did your Cameron Sino last? I was going to get one of these but if it's only going to last 6 months it's not really worth it..

Do you have any further info on this? I'm still quite sceptical that my battery is entirely to blame for my woeful 2 hours max playback, as this happened within a week of installing Rockbox. I know there were initially issues with the USBOTG chip but I have a friend whose battery died the same way and she installed Rockbox after the supposed fix for this .

I guess we know that on average people are getting from 1 to 2 years from the original iriver 1300mAH batteries.So we may need to wait a bit until we can be sure if the no name cheapo 2200mAH replacements are going to last for a similiar time.
I wonder if the Newertech or Cameron Sino ones are really any better than the ebay cheapos seeing as they are also made in Korea or China.

Is it a case of qualty control or are we just getting an identical product with a brandname stuck on it?

I have a cheap one and Im hesitant to try it until my original battery goes down!

My link on the item on ebay is a Cameron Sino one.

Thought I'd report i've found a good supplier of ipod betteries for anyone in the UK.

www.advancedmp3players.co.uk are selling Sonnet batteries for £24.99. I've had very good experiences with them befor, although i've never bought a battery from them. Very good service IMO.

...also, something that came as a surprise to me, the only review was by someone with a h340 who linked to my guide here lol.

[Cputoys]

i opted to go with an ipods99.com battery mainly so i didn't have to fool with the molex plug (changing polarity). They have a video on google http://video.google.com/videoplay?do...26546715798036 which truly is worth a thousand words and have included as part of the "kit" - the mini-screwdriver and prying tool for the case. The battery is only 1700 mAh, larger than the original h300 battery, but not as large as some of the ipod batteries out there. Works for me.

[Cyberflow]

Just bought my Battery, it's the NuPower one. With 2200mAh =)

Can't wait to put this new battery in it and have more hours =)

[Cyberflow]

Btw, nice little video by ipods99.com

[chrisp_h340]

Am I right in thinking that the ipod batteries that require a swap of the leads to the molex still have the black and the red in the same position as the original iriver battery?I dont have a multimeter with me as Im away from home,but my replacement seems to have the same colours to the same pins as the original.
Do I still need to swap them .It is sold as a 2200mah ipod replacement.

BTW my original battery died in 9h50mins with the iriver firmware 1.29k do you guys agree that that makes it pretty well shot.

heres the setup usedfor the test, I think its the recomended way:

xxxxxxxxxxxx
H340 Battery check:

original 1300mah battery
charged complete plus one hour!!

IRIVER FW 1.29k
vol 20
mp3 128k cbr
lcd brightness:0
no remote
senheiser earplugs
no eq

1 dir on repeat: (1 album of 80mins at 128kmp3)
screen on about 4 times very briefly


start time : 2 nov 2006 23.20
finish time: 3 nov 2006 09.10

total time 9h 50min

xxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxx

Shouldnt it be nearer 14 hours?

oh and one thing that has me puzzled why does rockbox (experimental build) show a remaining time for battery life of just over 8hours with a fully charged 1300mah battery?Is it a hangover from the old days before they worked out the USB OTG power drain or is it a realistic time if ur shuffling around and using the screen?

[jimdearras]

I would check the voltage with a voltohmmeter. Red should be positive, and black negative. But I wouldn't bet my H120 on that without verifying, in your case.

Yes, stock battery should last 16 hours in your test. The 2200 will last close to 30!

Short charge time (when the battery is fully discharged) is a bad sign. The charger circuit supplies 500ma. If you assume 80% storage efficency, that's 400mah charge. 1300mah/400mah = just over three hours for a full charge on the stock battery. 2200/400 = 5.5 hours to charge the 2200mah battery.

[chrisp_h340]

Thanks for that Jim.Yes it does charge pretty quickly..I guess i will be putting the new battery in.I wanted to do it anyway!Just better check the polarity first Hmm...

Thanks Saints for starting this thread. The battery on my 2 year old H340 was down to about 3 hours so I bought this one https://www.circuitcentral.com.au/pr...roductid=31091

The new battery arrived the day after I ordered it.

I mainly used Dennys guide (which is great) on changing the battery but I also found this video on youtube which also helped. http://www.youtube.com/watch?v=6HOnpHSgMvw The video comes from iPods99.com.

The only fiddly bit was changing over the black and red cables on the ipod battery. Of course I broke one of the little prongs on the new battery plug. I wasn't sure if this was going to be a problem so I just used the plug from the old battery.

Anyhow, the new battery is in place, the H340 is working perfectly I'm looking forward to great new battery life.

Thanks again Saints and Denny

[chrisp_h340]

Ive just done the battery replacement on the h340 and think it might help to let people know that although the new 2200mAh battery was sold as an ipod replacement the cables to the molex connector did not need swapping.

The red and black cables were already in the correct pins on the new batterys plug.The new battery is working nicely so clearly the polarity is correct.

The battery is a no name and in the packaging and instruction leaflet it is described as an ipod replacement.Although it does have the same serial number that is mentioned again and again in these threads (if only I could find it again)

I hope that this might help to save anyone else from swapping the connector if they do not need to.

I cant give any more info as regards where to buy the battery as it came with a second hand H340 that I bought from ebay,(My H320 was stolen 6 months ago).

Thanks to Denny for his excellent guide http://www.misticriver.net/showthread.php?t=34257

and also to ipods99 for the video.

I did find it perfectly okay to flip up the motherboard in the way shown in the ipods99 video (just make sure the little tiny white holding pegs are unclipped from the board). Although it is quite a scary thing to do there is just enough flexibility in the top of the back casing to clear all the top connectors.

The beauty of this method is that the screen does not get dusty ,something that other people have mentioned to be a time consuming part of the whole battery change mod.

It did fit back together nicely ,tighter but snug.
Hope that this might help others in a similar situation.

Am now looking forward to checking out the new battery life.

By the way sorry if i double post this but its hard to know the best place to put stuff as there are a few similar threads running.

Good luck to anyone else doing a battery replacement.

This next go round I'll try the Newertech or Cameron Sino. unless someone else in this thread found the killer $15 2200 mah battery

I hear what you are saying...Maybe we could start a thread to find out how long the cheapo batteries are lasting.

[Francis H120]

Hello all this is my first post. Recently bought a 2nd hand H120. Battery life is short so I've been checking this thread out and am going to do a change. 2 questions:

1. Maplins has been mentioned on here as a source of batteries for UK peepz. Can anyone who's fitted one of these confirm it lasts - i.e. doesn't drop off too much in less than 6 months? If these are good I'll get one, otherwise go for that eBay seller with the Cameron Sinos.

2. I've read all the stuff about some batteries needing the polarity swapping. I haven't watched the vids etc. but can I confirm that's what is meant is that some have the red and black wires the opposite way round in the connector? So as long as I make sure that red is still going to the pin it used to I'm OK? There's nothing silly like red negative leads or something going on is there!!??

Hey Francis, ive read some people have had problems with Maplins and others havent, Id go to ebay and get a Cameron Sino, as there are no reported failures (yet) and yes its just switching the wires you can see pics in Dennys thread on replacement, (link is in my signature), good luck

[Francis H120]

Cheers done it (as in eBayed one). A tenner (UK£). At that I guess I can afford to experiment as I feel reasonably confident about the replacement (cutting the old battery wires and soldering to them sounds like an easy alterative if you're fairly proficient with an iron).
