Li-Ion Battery replacement

Hi,

I have one of these Vosonic VP300 Mp3-cum-card reader HDD based device. It uses a very slim 7.2v Li-Ion battery.

I am wondering if some other battery can be used to replace the OEM ones. The replacement battery has to be the same dimensions because the battery fits in the back between the device and the HDD mount so the space available for the battery is fixed. I am looking at a replacement (probably some cell phone battery) because the OEM batteries aren't locally available in India.

Thanks,

Siddhartha

The battery is specified as two Li+ (actually probably Li-Polymer from that set of dimensions) 720mAH batteries. They are wired in series (nominal Li+ terminal voltage is 3.7V).

You might want to use that as a guide to see if anyone carries such a device near you.

Cheers

Probably not.This battery looks very long, too long to fit into a cell phone, and has a cable with a plugh, which was *never* a way to connect batteries to cell phones.Isn't it possible to order the OEM one for your device?

I will have to get them from Australia. One battery costs US$27, which is ok, but the shipping is $24!! So thats my last option.

It might reduce your per unit cost if you order more than one, which probably won't increase the shipping cost.

As Pete already pointed out, these are LiPoly accus. Since model airplane pilots like these accu cells, it would be easiest to find a store or online shop which carries this kind of stuff. You will get single cells, so you need 2. These are sometimes labeled as "Kokams". Bring your old pack to check the dimensions.
