high capacity battery clones for Hanlin V3/Bebook
In the process of researching/buying the Hanlin v3 at the moment. I've noticed it takes Nokia BL-4C, BL-5C and clones and the default battery has a rating of 950 mAH
On ebay you can get much higher rated clones (eg 1400 mAh and 1800 mAh) for a pittance - ie a few Aussie dollars and often including a battery charger.
Has anyone tried out any higher rated battery than the default and have they done any tests on effect on Hanlin battery life. Or does anyone have any thoughts on this ?
I know the battery life is already great at 950 mAh (eg approx 8000 page turns) but for a few dollars is there any harm increasing this to 1000 pages plus ?
Thanks for any thoughts
PS I did this with my panasonic cordless phone (ie bought higher rated batteries) and extended battery life is really noticeable

In my experience, (Palm T3, Nokia 770 batteries) I have had no success at all with these so-called high capacity batteries, even from different sources - ebay and local. Battery capacity was always lower than the original part, and the batteries always deteriorated more quickly as well - often lasting less than a year. Of course, when buying on ebay, by the time you've discovered the battery has a quite low capacity, it is too late to return it.
I'm not saying good high capacity batteries don't exist, just that I've never bought one.
However, the Hanlin battery probably isn't anything special so may more easily be improved on. I certainly don't get anything like the 7000 page turns as rated with my current BeBook battery. More like 1000 page turns although I never turn the device off.
I wouldn't expect significantly more capacity in a package the same size as the original. I see Jinke offer replacement batteries very cheaply, maybe BeBook and the others would be interested in doing so as well.
I don't think that buying an expensive battery will always get you a high quality battery, but buying a cheap one almost certainly won't.

From my experience, switching to original Nokia BL-5c battery increases battery life, and noticeably. At least I can easily get 3-4 weeks (without turning device off) and about 2500 page turns during these weeks.
But cheap chinease batteries sold on Ebay aren't as good, also tried several (on my PDAs - Sony and iPaq), didn't notice great improvement.

I know this is an ancient thread...please don't beat me for posting to it ?!?
I have found a cousin of these readers - a near clone of the Astak EZReader, and since it was very inexpensive I bought one.
It arrived minus any battery - boohoohoo !!
I found that the spare Nokia BL-5C battery for my phone fits the slot and powers it up, but it is too thick for the battery door to shut on this reader.
From what I can find by searching, the Nokia BL-4C battery is very close in size & capacity, but thinner - so I'm thinking that it may fit but I do not have one to be able to check it.
Has anyone got both of these batteries and could you confirm that they are almost the same but that the Nokia BL-4C is just thinner ??
Thanks for any help.
Another battery that seems to be the same as the Nokia BL-4C battery is a generic number 423450 battery, but since those sites listing it are in other languages it is difficult to be certain...

I've just used a micrometer on four BL-5Cs and there seems to be minor variations in depth. Looking closely the thickest part of the battery is the plastic "flange" at each end; you might be able to pare a bit off there to get the width down to the same thickness as the body (the label which wraps round can extend over the flange and increase the thickness unnecessarily). I have performed "surgery" on a camera battery to provide an index indentation on a cheap replacement battery rather than pay 10x the price for a "proper" one - a bit of ingenuity can be financially rewarding with things like this.
Beware of some allegedly very high capacity batteries (I got a Chinese one marked 2450mA/H). Unless the actual discharge rate and end voltage is quoted capacity comparisons can be misleading.

Thanks for pitching in BobC.
I may just have to jump in and buy a BL-4C just to test one...
Trouble is that this reader, unlike the EZReader, has a very dinky battery door with tiny plastic hooks rather than burly tabs and a screw to fasten it.
I may try removing the label from a spare BL-5C, but I doubt that I could slim it enough to get the door on without breaking the dainty thing.
On the other hand - it may be just as well (though uglier) to just use the thicker battery and some clear tape and call it good...only time will tell.
I am still very glad to have found this model as I have always been worried as to what I might use to replace what I have, which is perfectly suited to my preferences.
A friend of mine also wants a reader - really liked mine - and now that I have this one in-hand I can honestly recommend it as comparable.
