Go ask les Schwab if your battery warranty is up
You can also call them, and they will be able to look it up and let you know as well.
There should be a date stamp on the battery. Abbreviated month and last two digits of the year; this indicated the date it was sold. Most batteries are 1 year free replacement and prorate thereafter. There is also a code embossed in the plastic casing of the battery. Best thing; take it to the pros.
There should be a date sticker on the battery. If not, stop by any Les Schwab store and they will check it.
