When you turn over the engine the battery voltage drops so the alarm sounds as it thinks the battery has been disconnected.
Main battery must be losing charge - keep it topped or replace, |

Cheers kmac.
Taking it out on an extended run tomorrow so will give it a decent charge. Will then turn over daily and see if the it is losing charge relatively quickly or just when left for long periods if time. |

I had a similar issue and after lots of head scratching found a bad bulb causing a short and draining the battery quicker than normal, bulb fixed and no more problems still running fine on the same odyssey pc1500 5 years later

Any tips for getting to the bottom of what was causing the battery drain?

For your info
If you talk to Oddesy they will tell you to, at least once a year take the out of the system and give them a full bench charge with a quality charger such as a ctek charger. It certainly helped mine when I did what was recommended |

Andydef90 - Both batteries are about 4 years old.

I have two Defender 2.2. One used every day, the other once a week at best. Both turnover quickly and start immediately. I get a alarm, often on both, sounds like a bird whistling ( no birds were harmed in the writing of this thread) is this the alarm to which you refer as I’ve often wondered what it is.

The hard way - remove all fuses and start putting them back one by one whilst measuring if there is any draw on the batter |

Hmmm, using the tool seems to be a less laborious option.

Kind of lost track of time. Battery or batteries do need a charge. Any suggestions for a charger and whether it can be done in situ or better to remove them and charge indepently?

Have a search for CTEK on here will find you a range of options; including some of the best kit for charging insitu.
