Replacement battery dimensions (SL572035) for Radsone earstu

by Es100owner on Sat Jul 04, 2020 8:28 am

Hi all,

I'm looking to purchase a replacement battery for a Radsone earstudio es100. The battery inside is SL572035 3.7v 350mAh. This battery appears to be discontinued.

I have found the following two batteries on this website, and want to check whether they have the exact same physical dimensions as the original (or smaller) as the battery must fit inside a small casing.

Lp402025 https://www.adafruit.com/product/1317
Lp552035 https://www.adafruit.com/product/2750

Are the numbers related to the dimensions of the battery?

Thanks for any and all assistance.

If you scroll down to the "Technical Details" on those product pages, the dimensions of the cells are posted.

Another variable to be aware of is the polarity of the connector. Some manufacturers wire them one way, some wire them the other. Double check before connecting the cell. It is not difficult to swap the wires in the connector if necessary.

Edit, this page shows 2 sets of dimensions in the specifications

Thanks for pointing that out. The first set of dimensions looks more believable for a 350mAh cell. But I'll have our web-team verify that and correct the page.
