If you wish to use your telescope in the field or do not have access to a 220V mains power supply, you will need a battery. Depending on the battery capacity and telescope mount, it can power your mount and other accessories for varying lengths of time. (Operating time depends on the condition of the battery, the temperature and, naturally, the mount’s power consumption.)
The 12V/9Ah battery can power SkyWatcher EQ-3/5/HEQ-5/EQ-6/AZ-GT mounts for approximately 4.5–6 hours. (Smaller single-arm GoTo mounts can be powered for approximately 15–18 hours.)
The 6V/4Ah battery is recommended for SkyWatcher EQ-2/EQ-3/EQ-5 stepper motor controllers, in both single- and dual-axis versions. It can power the motors for approximately 15–20 hours.
Our charger has an output of 0.8A, allowing the batteries to be recharged. It features both fast-charging and trickle-charging modes for gentle charging. The unit also includes short-term short-circuit and reverse-polarity protection for up to 1 minute. An LED indicator makes operation easier by showing the charging status: the red LED turns green when the battery is fully charged.
A power cable can be purchased separately for the package, depending on the type of mount or other external device. The battery charger is not included in the package and can be purchased separately.
