Correct Battery?

[900MAN]

First off I wonder if mine's gone.
The optimate says it's ok, it appears to charge (14.1v whilst running) but after a 12 mile ride the other day didn't have enough in it to start, even the lo bat came up.

Just seen this on ebay

Which is the better/correct battery? one has BS at the end whilst the other has B4?

Cheers

what do you think of these gel batts that are supposed to offer a better start?
