One of the many reasons I use the little micro size Yaesu VX3 hand held is the super low cost of batteries. (They use the very common NP60 camera battery, Available everywhere, Including Ebay)
A PAIR (2) new batteries including shipping for less than 7 bucks is good!http://www.ebay.com/itm/Wholesale-2pcs-NP-60-Battery-fo-HP-Photosmart-R507-R607XI-R707xi-R07-/140630293124?pt=Batteries_Chargers&hash=item20be37fa84
I have been using the little VX3 for years now with these batteries, Some seem better than others.
At less than $3.50 each, If you don't like a battery, Just toss it out and put in a new one!
(I use that radio every day, And have it on for well over 12 hours a day. Some of those Ebay batteries have lasted well over two years!)
