Hey all, I bought this charger from Jaycar $133.95 (got 2) and it is fantastic. I just use the slow charge and the bike was 80% full in 3 hours.

It is dead simple to use and you can see different readouts e..g % full, amps, rate etc. Has all the modern safety features wont create leakge or overcharge etc.
15A Intelligent 5 Stage Battery Charger
The perfect charger for any garage. Microprocessor controlled for not just charging your batteries, but maintaining peak performance and long term maintenance of your 12V batteries. It's suitable for all flooded and gel acid batteries, including deep cycle batteries. If the temperature changes, it will compensate and also compensates for voltage drops in the cables. It's also ultra-portable with a handy storage pocket in the back for the leads. Simply select the battery type and charge rate and hit the start button. The charger operates in five stages:
1. Soft Start - tests the battery condition. A severely discharged battery needs charging with a reduced current until the voltage reaches 10V.
2. Bulk charging - delivers most of the charge (60-80%). The charger delivers maximum current until the terminal voltage has risen to the set level.
3. Absorption - completes the charging up to nearly 100% at a constant voltage. The current tapers off as the battery reaches full capacity.
4. Float - maintenance charging at constant voltage, keeping the battery at 100% charge.
5. Pulse - long term maintenance charging. Cycles the battery between 80 and 100% charge for maximum battery life. The battery receives a pulse, starting a new charge cycle, when voltage drops to set limit. The charger can be connected for months keeping the batteries fresh.
