Best Battery Isolators UK
Battery isolators protect your starter battery from being drained by leisure loads and allow charging both batteries while driving.
Types
- Manual switch: Simple ON/OFF switch. £8-15. You remember to switch it.

- DC-DC charger: Smart charger that conditions power. Best for lithium. £50-120.
Recommendations
| Use Case | Best Option | Cost |
|---|---|---|
| Budget lead-acid | VSR (Durite) | £30 |
| Lithium battery | DC-DC (Victron Orion) | £90 |
| Simple system | Manual switch | £10 |
Installation
- VSRs need a trigger wire (usually alternator signal or D+)
