Don't have any buttons left to compare, but maybe this will help a little...
Here's an LG HG 2 side by side with Samsung 25R and new version VTC-5. Negligible difference in size - not even 1 mm.
Here's the LG in a 2015 woodvil
I realize that spring looks REALLY squished. It's not that bad - here's a closeup...
And here's side by side, LG in a Grand, and Sammy in the Woodvil.
Baby blue only looks taller because it STARTS higher in a Woodvil...
Again - I know spring looks really compressed here, but I'm pretty sure I'd know if it dropped. Honestly, the only time I truly shorted something, I knew
and reacted so fast that the spring didn't have to drop.
I would really like to see pics of these new batteries in a REO. In the Grand and in the Woodvil. Also would like to see the difference in them in button top and flat.
I know my Samsung 25R button tops work in my Woodvils but are just too long for me to feel safe in the Grand. The flat tops give me marginal security in case of a short. Not much spring left to drop.
