Adaptive Charging Algorithm Explained
The charger’s 3-stage charging ensures your battery is optimally charged without damage:
- Bulk Stage: Maximum current to quickly recharge the battery.
- Absorption Stage: Controlled voltage to safely bring the battery to full charge.
- Float Stage: Maintains the battery at full charge to compensate for self-discharge.
For lead-acid batteries, the absorption time adapts depending on the depth of discharge, preventing overcharging. For lithium batteries, the absorption time is fixed at 2 hours by default, but you can choose a fixed output voltage if preferred.

Non-Isolated vs Isolated DC-DC Chargers: What’s the Difference?
The Victron Orion-Tr Smart 12/12-18A is a non-isolated charger, meaning the input and output share a common negative connection. This design is common in automotive systems where batteries share the vehicle chassis as negative.
When to choose non-isolated:
- Vehicle setups where both batteries are chassis grounded.
- Systems where simpler wiring and lower cost are priorities.
- Applications where isolation is not required for noise reduction or corrosion prevention.
When isolated chargers are preferred:
- Marine environments where corrosion and grounding issues are concerns.
- Systems needing electrical isolation to prevent noise or interference between battery banks.
Victron offers both isolated and non-isolated options to suit different needs.
