### ⭐⭐⭐⭐⭐ Bleeping marvellous!
*by K***N on 4 November 2023*

Faced with swapping the ageing battery in my VW Golf, I didn't want the additional hassle of resetting the clock, adding all the radio stations or anything else that might have been lost due to the battery being removed. So, I have a new battery for the car. The previous battery is still in the car, and... I had a spare older 12V battery - not enough to turn an engine over, but enough current to keep a few electronic circuits running. The instructions supplied are in Chinese. I used a well-known search company translation app to understand what to do. 1. I attached the OBD saver to the spare battery. 2. The unit began to beep repeatedly and the red LED lit up. 3. I plugged this into the ODB socket in the driver footwell. 4. I undid the negative battery lead from the car battery (10mm spanner). 5. I undid the positive battery lead from the car battery (10mm spanner). 6. I removed the fleecy jacket from the battery. 7. I removed the nut and clip holding the battery to the chassis (13mm spanner). 8. I removed the existing car battery. 9. The OBD saver was still beeping merrily. 10. I placed the new battery in the chassis tray. 11. I replaced the nut and clip to hold the new battery in place. 12. I replaced the fleecy jacket. 13. I replaced the positive battery lead and secured it again. 14. I replaced the negative battery lead and secured it again. 15. I removed the positive clip from the old spare battery and the OBD saver continued to beep. 16. I removed the OBD saver from the car. 17. The clock was correct, the radio stations were intact. 18. I turned the ignition and the car started in less than half the time of the previous battery. 19. I looked in the mirror and winked at myself for doing a good job. 20. I took a short time to rest and type this review. Apart from the Chinese instructions, this was very straightforward to use. I was back in the house in under 10 minutes and that included putting away the old spare battery in the garage and tidying away the tools I used.
