EverStart ES9BS Battery - * Awesome! *

I had got this battery a 2 or 3 years ago from Walmart but last fall I didn't bother to take it out for charging as I was planning on putting a lighter battery in this spring.

Anyways, today I got the itch to take the bike out and to my amazement with the old battery it was cranking like a champ! I couldn't believe how strong it still was! I guess when they say "maintenance free" they're not kidding

Really? I had officially labeled this brand "NeverStart" as mine completely died shortly after a year of use (Charging system wasnt the issue). Anyways I'm in the market for a new Battery...anyone have a recommendation? http://www.fsmotorcycle.com/motorcycle-parts/electrical/yuasa-ytz10s-activated-battery.html Damn thing is $140 should i just invest in one of those newer Shorai or ballistic ones instead?
