And by working, you mean using 4 1.5 V AA alkalines in a plain battery case, used with an iHP-140?

Thanks (yep, I'm skittish about this--too many fried player stories!)--

If your worried PM NPswimdude he will tell you about it. He is a definate example. I dont want to be the only one to assert those worries.

Mike · #**124** (**permalink**) March 3rd, 2005, 08:09 AM

Anyone else with experience/advice here?

**NPswimdude500** · #**125** (**permalink**) March 3rd, 2005, 01:34 PM

i'm using 4x1.5v AAA disposable rayovac batteries, and there have been no problems. i have charged the player ~10 times with my pack so far, and there hasn't been a single hitch (of course, i had to replace the AAAs to charge it this many times)

exactly that. albeit with AAAs (which only differ in mAh, i believe)

Astec · #**126** (**permalink**) March 3rd, 2005, 01:39 PM

So there you have it Mike. The definitive answer. Hope that asserts all the fears you have and that you have a good time making it. Any problems PM me or post in the BP thread. Thats an open invite to anyone with questions.

and whats especially nice is, there are so many different everyday items out there that can be used as a case for your battery pack. case-in-point....an altoids tin

Astec · #**128** (**permalink**) March 3rd, 2005, 01:44 PM

I have a tape box. An old necklace box and a few in the works.

Mike · #**129** (**permalink**) March 3rd, 2005, 02:22 PM

Thanks! Still feel more comfortable with rechargeables, at 4.8 V (1.2 V x 4) ...

Anyone else, feel free to chime in with your experiences (or not) with 4 x AA for 6 V ...

Astec · #**130** (**permalink**) March 3rd, 2005, 02:40 PM

Mike you will find that a lot of rechargables will actually hold a little more about 1.3 in fresh decent ones. so its still over. But if your unhappy thats ok and understandable, but try it and if it goes wrong then RMA to iRiver. (I almost guarantee it wont have a problem no definitive as I dont own a h100 to test it on so dont want to shoot myself here).

Mike · #**131** (**permalink**) March 3rd, 2005, 03:30 PM

Thanks--just was seeing what others think as well, and what others' experiences have been.

Love having all these options, though!

The Sony PSP charger is 5V, 2A, -identical- to the iRiver charger, so this battery pack should be fine. I ordered one, so I'll be the guinea pig

At 3800 mAh, you should get a heap of playing time out of it (on your H140 or your PSP)!

On the iriver.com user forum, I found a thread on how to make you own external battery pack. Here is a link to the original thread.

I followed etrabal's instructions on that thread to build my version. Here is what he had to say:

My version ended up being a little different. I took apart the battery holder and replaced the wire that was in it with the "replacement adaptaplug socket" wire. This required a little soldering, but I think it looks better than if I'd just connected the wires and covered it with heat shrink or electrical tape. Also, I used Energizer 2300 mAh 1.2V batteries.

With the original battery that came with H140 I was getting around 2 1/2 full charges from it. The cost ended up being somewhere around $10-$15 plus the batteries.

The picture that I saw of the official iriver version for the H320 looked nicer, but the homemade version doesn't look too bad. However, I wish the plug was black so it would match everything else. Also, the case has a little philips head screw to hold the battery cover on. This is kind of a pain to take off when you need to charge the batteries.

If anyone knows of a better holder for 4 AA batteries, or a retail version that is available, please let me know.

Here are a couple of pics:

i know im seriously late on this. but the best thing you can do about unscrewing the case, depending on the size of the screw and threads. you are able to find millions of thumb screws for pcs. and im not shure what size screw fits into the case, but its an idea. i plan on making one of thoes before to long.

If you were to use the built-in battery first, then rely on the external pack it'll charge the built-in pack. There is some power loss doing it this way (overall lower running time for both packs combined)

Shame the iriver doesn't have a direct power jack as well that bypasses the charging circuit...so you can use off-board batteries only to operate the DAP, not charge as well.

Hey are you definite about it using the external battery pack as a power source? I've replaced the internal battery on mine for a 2100mAh one and am trying to suss out a way of making use of the old battery externally.
(apologies for multiple posting but I'm not getting very far with this.)

I soldered a plug on it and when I plugged it into the DC in the charge light came on. I unplugged it and my iRiver wouldn't switch on. The battery had not only not been charged, it been drained in the space of a few seconds by the external battery.

I'm thinking of soldering a second female plug into my iRiver as an external battery port but I'm not sure how to bypass the internal battery without actually unplugging the wires from the internal battery and swopping them for the external ones (which would also mean having to keep taking the bottom off my iRiver. Not very convenient.). Also I don't want to mess with the cosmetics of the case if I can avoid it.

Someone said less than 5V doesn't charge the battery but that doesn't seem to be the case.

Any ideas?

zezayer · #**137** (**permalink**) June 14th, 2005, 09:12 AM

couldnt u have a switch on the leads to the battery (with the internal battery connect if switch in 1 postion and the external battery if in the other.)(this could be done automatically if ur good @ electronics) so u can swap which battery is connected to the iriver. if it goes wrong uve only damaged a battery aswel, not ur player.

Cheatah... Ungowa! · #**138** (**permalink**) June 14th, 2005, 09:26 AM

Yeah, that's what I was thinking of doing but I'd still have to have a way of plugging in the external battery. If the internal battery isn't connected, the iRiver doesn't work.

And I don't want to have the external battery constantlay connnected and flapping around. It does just about squeeze into the case behind the iRiver (which is cool, way better than those AA and AAA external boxes) but I want to be able to plug/unplug it, and I need to be able to charge it too.

I've been PMing with Coreman about charging the external battery externally, if you know what I mean, using a mobile phone charger possibly; but it's a bit risky and I don't want to try that unless I know what I'm doing or someone who does can tell me.

Now wait a sec here... I heard that the psp power port is the same size as the h3xx series, which is bigger than the h1xx series. Maybe I'm wrong in this, but I'm fairly sure that this psp batt pack would work with the h3xx series, but would be too big for the h1xx series. mrmike, if and when you get it, could you update us?

mrmike · #**140** (**permalink**) June 16th, 2005, 06:49 AM

It just came, is pretty sturdy... you can't see it in the web picture, but along the joint (where the top/bottom halves meet), there's a green led that flashes when charging, and goes solid when fully charged.

Gorcorps, you're right.
The voltage/current/polarity is on the money, but the plug is too big.

Looks like I need to hit the Rat Shack for an adapter.

gorcorps · #**141** (**permalink**) June 16th, 2005, 08:07 AM

Ya, I thought it was

. A quick fix though, and you'll have a great battery pack there.

qwert-e · #**142** (**permalink**) June 20th, 2005, 08:31 AM

mr mike, i bought two of those amazing 3800mah battery packs last week and have been testing it over the weekend. I bought mine from an ebay seller. both of them didnt work!!! the green light comes on to indicate that its charging, but mysteriously the battery pack doesn't get hot, a sign that it isn't charging. sure enough, after 10 hours charging, the battery pack still would not output any power...

i'd live to hear that your one does work, but 3800mah for less than £15 does sound too good to be true to me.
