Antigravity has a promo code for $50 off the XP-3. It'll fit in your pocket and start anything from your bike to your truck. (or charge your electronic doohickys) http://shop.antigravitybatteries.com/micro-start-xp-3/ Promo code "advxp3" http://advrider.com/index.php?threads/micro-start-xp-3-super-deal.1128710/ I figured I'd try one out at that price.
Got it in on Saturday, needed it on Sunday. Had left my 350Z in the shop for a couple weeks and apparently the battery is on it's way out. It had enough juice to roll the windows up but not turn the starter. Hooked up the XP3 and it fired right up. The alternative was to push it out of the shop and jump it with the truck or maneuver my bike over into the corner to jump it off. My old lawn mower battery may have had enough charge to do it, but I figured I'd try this thing out.
