Query: A Better Idea!

I needed a replacement battery for my V170 and found that buying a Tracfone C139 phone on sale for $12.99 was a better idea, and Walmart sells them online for $12.88. The battery that comes standard with this phone is a new Motorola SNN5749A (the same as the V170), manufactured within the last year, and if your V170 quits working you have the C139 to use as a backup phone. It also has a travel charger (plug-in, thinner profile, and prongs that fold-in) versus the bulky one that came with the V170 and it works with both the V170 and C139. Just my opinion after looking everywhere for just the battery and getting frustrated that Motorola wanted $39.99 for an OEM battery.
