Hope someone can help...

My wife has a 2000 Suzuki Savage LS650. Unfortunately the battery died a while ago, and now that we've moved to Hawaii, we'd like to get out and ride. Ordered a replacement battery from the store, but trying to slide the battery into the battery compartment doesn't work.

There's a bracket on the closed end of the compartment which is elevated in the center and provides adequate clearance, but the front and back of the battery butts up against this bracket, preventing the battery from seating all the way in. I'd say the replacement battery was the wrong model, but it's also the one that comes up in web searches as the correct model. The battery box says it replaces "B14L-A2" and "YTX14AHL-BS" and it's a sealed battery. The old battery, which was also a replacement from a few years ago wasn't sealed, and fit the compartment with room to spare.

Anyone have any ideas?

The new battery should be better than the stock.
Stock the bike comes with a regular /white/ cheap battery. Any sealed/black/ battery that has the same dimensions and has the "L" in the number, which is the way "+" and "-" are, will be better.
