My wife just ordered a replacement battery for her rezound. At first glance it appears identical, but wouldn't seat in the battery compartment. I checked and noticed the tabs in the bottom corner are slightly different shapes.

Upon further inspection, I see that the battery voltage is 3.7 rather than 3.8, and the part number of the battery is off by one digit. However, both batteries say "Phone Model: ADR6425", which matches the rezound.

Anyone know what gives here?

Would it be safe to simply file the notch slightly to make it fit since it seems otherwise to be the same battery?

Any help is appreciated

 

Thanks for the feedback. I ended up writing the vendor, and they sent another battery (the 3.8v) free of charge.

Unfortunately the whole phone seems to have just taken a dump, a few weeks later.
