I have seen several threads on batrety care but did not see the answer to my question. Please forgive me if I missed it.

Our 2010 RT-SE battery is weakening. It left DW stranded at the gas station this am. It was only off the battery tender for a week........

Anyway, the local stealer has to order one. Really?? It will be a week at least based on past experience.

I saw in the specs it needs a 21ah 12V battery. Is there a specific size?? As long as the ah is correct and it is sealed can I get just any motorcycle battery??

I have read the OEM is a good battery. Is it better to just wait and keep it in the charger/tender until the new one arrives?
