    Installed this battery in a 2007 HD Herritage in December 2010. Bike is ridden year round so it hasn't been stored. Been having hard starting problems, so I checked it with a meter. Only putting out 10 volts. Didn't last much longer than the warranty.

        I purchased this battery for my 1986 Hond Goldwing as my last battery only lasted two years and required maintenance. This has a great warranty comparably. High Cold Cranking Amps (CCA) and is maintenance free!

                    This battery replaces a PC680 lightweight battery for use in my 2004 STi. Where the PC680 struggled on cold days the ext-18l shines with its higher CCA rating. It accepts M6 threaded terminal posts although it's not clearly shown in the pictures.

                                  Do I need to keep this battery on a trickle charger when not using it for a few weeks at a time? The charger light goes from amber to green in just a few minutes.

                                    A:

                                    Most batteries will self discharge in about 3 months, or about 90 days. This means that the self discharge rate is about one percent per day, so a trickle charger is used in such cases. At the end of the charge cycle, when the green ready light is on, the charger is trickle charging the battery in constant voltage float/standby mode, nominally at 2.3 Volts per cell. This is the same charge method used for batteries in standby applications such as alarm panels or emergency lighting, where the battery is intended to be charged 24 hours a day, every day. At this voltage, the battery will not be gassing so loss of electrolyte is minimal. The charge current drops exponentially to a very low level, sufficient to maintain the battery in a fully charged state and to compensate for any self discharge. Over time this low rate of charge will tend to equalise charge imbalance between the cells, which can extend the battery life. By leaving the charger switched on, you will prevent any risk of damage to the battery from sulphation (which can be caused by allowing the battery to stand in the discharged state). The energy consumed in standby mode is minimal, typically about 10 Watts for a medium size charger.

                                  Can this battery be mounted on its side? Can you supply amp hours and reserve minutes?

                                    I would not recommend mounting this battery on its side as the acid in the battery would probably leak out.

                                    Mine is marked 330 CCA. No other data on the battery or the package. It is pre-filled and sealed so it could be mounted sideways.
