I went go order two BP2EX's today, and damned if the Sony DAPC didn't have anymore!

So, does anybody know where I can get my hands on an OEM battery?

 

[Duncan]

Hmm... me too - I want / need five of the things

You would think that a similar size Lithium battery would exist. I tried to replace a BP-5 at Rat-Shack and they couldn't help. You could always hook up an external battery pack to the DC connector if you really want to take your old discman for a walk.

hehe... cheaper one here

Hrmm, thanks for the two battery distributors Duncan/Pete.

What I was thinking, would it be possible to fashion a normal 9v into the battery compartment by creating a simple conversion pcb or cable. I think it's feasible. Anybody else think so?

Does any one know if the old 9V charging circuits are OK for these newer Li batteries ? Hmm, looking at the d88, maybe there is no circuit...
DV.

I don't think it is deep enough. (9v too fat)

External bat pack not gonna work for you tbdoah?

I'm still considering other solutions as well. (I have a batt pack I made. thread here . Still haven't sanded it down, and clear coated yet, though.)

Guys,

I thought that the BP-2EX is a lead-acid battery. According to the mentioned website, that is li-ion battery. Are u sure whether the li-ion is the right kind of battery. If "yes" this is very nice, b/c li-ion is free from memory effect and can be recharged during while operating.

Purk...

Its a part for part replacement for a camcorder (can't remember the model # now)... so i'm not 110% sure if there were two versions of the BP2... lead acid, and lithium, but I can't see it some how...

I'm another person interested in what effect charging a li-on battery in a lead acid charger will have

 

[D555]

I must have gotten one of the last ones....

Maybe it all works out, but recharging circuits are designed for the particular battery type, NiCd, NiMH, Lithium-Ion, Lead Acid, etc. which have their own recharging characteristics.

It is not recommended to mix types and chargers.

Yup, I tried to fit a 9v into the pack, not gonna fit.

AFAIK, th BP-2EX shipped with PCDP's are lead-acid, as the 14 year old one from my D555 is lead acid (too bad it doesn't hold a charge), as well as the one I ordered from the DAPC in January of '03.

Anyway, I guess the only route will be trying to land a lead-acid, which, most of those battery replacement "superstores" only carry the Li-Ion.

Well, if the Lithium is the right size and voltage I'd still keep it on the list. All you need to worry about is charging it ; a matter of getting the spec sheet for the optimal V and mA. Who knows, maybe 4.5, 6 or 9V @ 300 mA is OK

Hrm, so now we need a charger for 3.6v Li-ion battery. (is this 3 1.2v cells? anyone know?)

I would definitely recommend against this for the older CD players. My D-2, for example, draws 200mA while playing...an alkaline 9V battery is only good for a 40-60mA draw. More than that and you get into nonlinear voltage drops and lots of heat. Besides, it would only last a couple of hours at best. Rechargeable 9Vs can take more current draw but they have even less capacity, maybe an hour's worth of play time.
