Buying Guide
- Battery compatibility: Check that the tender supports 12V lead-acid types (flooded, AGM, gel) and any Lithium options if relevant to your bike’s battery.
- Charging profile: Look for multi-stage charging or maintenance modes that prevent overcharging and extend battery life. Desulfation and pulse maintenance can help older batteries.
- Automatic operation: A key feature for UK riders who store bikes for months. A good tender should start, finish, and maintain without manual intervention.
- Safety features: Spark-free operation, reverse polarity protection, and overcharge safeguards are essential for safe garage use.
- Power and connections: Consider the amperage necessary for your battery size (2–8A is common for motorcycles) and the flexibility of lead lengths and connector options (SAE, ring terminals, clips).
- Durability and weather resistance: IP-rated units (e.g., IP65/IP68) perform better in outdoor sheds or damp garages; rugged housings reduce wear from UK climates.
- Long-term use: If you intend to leave the tender connected for extended periods, choose a model with proven reliability and a reputable warranty.
- UK plug compatibility: Ensure the model includes a UK plug or compatible adapter, especially for seasonal or storage setups.
- Maintenance for Lithium batteries: If using LiFePO4 or other Lithium chemistries, verify the tender explicitly supports these chemistries to avoid potential damage.
