Presuming the new battery had a full charge when fitted (honestly not all of them do) then the charge should last longer than ten days even with the items drawing power you mention. For those who like Welsh Mountains and narrow boats have a look at my videos and photos at..

Something is not right, it should last longer than that.

I'd say you have an excessive drain..
Not sure what the acceptable paracitic drain is on a defender but would be unlikely to exceed 50 mili amps.. Most probably less.. So at that sort of draw you could expect 3 or 4 weeks at least and still expect a start.. You really need to determine what the draw is.. Then try and trace it by isolating circuits.. |

If you have a clamp meter for checking current your task will be much easier.. Save breaking in to the circuit. And it should be sensitive enough for this task..
This is the one I use..  Click image to enlarge |

I would generally expect a battery to last 3-5 weeks. Charlie

I know mine's a 2.2, but I get about 3-4 weeks of sitting and a good start, little sluggish, but nothing I would consider poor.
Did you chage the battery prior to installation, or after fitting go for a long run to fully charge and condition the battery? Even the VARTA I got from Tayna Batteries needed an overnight top up from a CTEK MXS 5 (5 amp chager) before I did the install.

If I’ve done this right I’m getting a reading of 02.48 (clamp multi meter I’ve disconnected the negative battery terminal and clamped to that set to dc 60A)

Not sure I'm following you correctly.. You can measure the current on the negative lead from battery to chassi.. But it has to be connected.. If it wasn't connected you wouldn't have a circuit and the reading should be zero..
2.48 amps is high.. Your battery wouldn't be good for more than a day at that drain.. Your meter is on the dc scale??? |

Ah okay the guide I found said to disconnect the negative use the red to the cars negative and black to the battery negative but I wasn’t getting anything so I used the clamp to the negative lead. I’ll reconnect and try it how you have said, Thank you will update wi the results!

The clamp type meter doesn't require the circuit to be broken and leads attached.. That is the case with traditional multimeters..
With the clamp meter just switch it to the current setting and place the clamp around one of the circuit wires.. As I said make sure it's on the dc scale.. That should give you a reading.. It ma take a few seconds to settle to a steady reading.. I'm sure there will be plenty on you tube, which will cover it far more clearly than me👍 |

The clamp Amp meter is not as accurate as wiring in the Amp meter (in serial with the battery). The clamp is great for reading high amps without being able to disconnect like: is my alternator charging. When you wire in the Amp meter you can easily fry your meter as it typically only rated for 2 or 10 Amps and if you are lucky has a fuse.
To measure parasitic losses that would drain a battery you are looking at ~250 - 500mA (0.25-0.5A) so you can disconnect the single negative battery lead and then wire in your Amp meter between the battery terminal and the negative lead. Then don't switch on the car because any large draw will go through your amp meter.. With the parasitic loss shown you can now start pulling fuses one by one to see where the losses take place. I bet you it is the radio or any aftermarket alarm system so start there. |
