Very good info Caddyshack, Thank you. I they changed something, they made the part compatible with older models, at least, good.
Nakos : You were right. As I measure with analogic Ampmeter, I got the reading immediatly and that was enough for me. But if I keep longuer at measuring, the intensity draw really get changed in 3 steps.
at the final step, waiting a few seconds, I have only 60mA left !
Electronic stuff is “living”, not like passive resistance.
But this is still enough to kill the battery within a few days. 7 days to reach 50% SOC, 14 days to dead.
Lost of people go this AGM battery swelled. I think this happens this way :
1/battery is discharged slowly during a few days of non-use
2/when the user take the road, the charger pushes strong amp to recharge it, from the traction battery but this kind of battery should have a max push Amp of a few 2 or 3 amps, if go over, the gasses emitted inside can’t be recombined and the pressure get high, swelling the cover. This would be too much Amps at charging.
This kind of battery can allow strong draw but can’t be charged strong.(a)
now why have too much amps at on the road charging ?
in fact, it’s impossible not to have : on the road, the charger have to immediatly compensate for head light and other stuff. the charger will not know how much amps are pulled, will only see the low voltage. Then, the charger will push strong amps at least to compensate the draw.
Normally the 12V battery would work well if never discharged, it will provide important energy reserve for lights and safety.
But within a few day of no use the twizy, I get discharged and this is the problem.
The solution is to allow the charger to charge from the main battery even twizy off, that’s what they did in the newer versions, and then the 12V battery would live much long.
I got the problem because the battery was so dead that it was totally discharged after 1 or 2 days without use.
As I have an old charger, I think the way to go is to shut off electricity to the 12V battery everyday, this way I’ll keep the 12V battery in good condition. Always keep well charged and seldom work.
it will not be possible to keep the clock on twizy, but that’s not big problem.
(a) never seen an AGM battery on a vehicule before, Renault problably decide to use it as it is care free, but the conceptor forgot the reasons why open batteries are still used on vehicles !!
now solved the problem with charging even twizy off.
