New battery, won't start...

[Whostheduke]

Just to complete this, it's now sorted. The old battery just needed charging from the looks of it. I got green flag out - they tested the new LI battery which came back as 'state of health 64% - bad and replace'. 

 

So I tried the old battery now with a full charge which worked (only after he'd started it off jump leads). 

 

I think this is basically what you guys were saying so thanks for the help

That's worrying for a new battery

Thanks for coming back and letting everyone know the outcome. As Stu says, very worrying for a new and probably not cheap battery.

Usually a LI battery becomes dead if SOC is below 10-15% and ideally you want to keep it between 20% and 80%.

The reason not to fit one on a motorbike is only if it will be left for long periods without running (over 4 weeks).

Bloody batteries man works just upgraded The trains to a gel battery that goes flat if left for more than 2-3 days

A battery should hold the charge easily for  1 week. My Honda's goes flat after 10 days because of the H.I.S.S. but I got an Oxford trickle charger to keep it top condition.

If you don't have alarm or any safety device that stays awake 24/7 then unfortunately I would think it is in fact something draining the battery.

Refer to my first comment. Get a multimeter and start chasing it. You could be lucky and find it in 1hr

The new battery i got for Xena is an AGM type and it's brilliant, even with the alarm and the parasitic drain in the form of a clock, I know even after a fortnight she will start, which has been the case sometimes this year

This isn’t on my bike or car, I work on the railway and if we leave the trains for more than 2-3 days depending on weather we have to go out with the jump pack or drag them into the sheds to put on charge

AH!

Just put some solar cells on the roof of the trains then

A less environmental solution is to get a small petrol generator and plug it to the train. should get a decent charge in 1hr
