Stock Battery 26 lbs, New Battery 6 lbs :shock:minispeed said:Do you know the weight of the stock lead acid and your new set up?

But how many drivers have been affected? Posts at MNL tend to skew toward those, perhaps few, who have problems. I've never had a problem with my 12V battery, but I'm certainly not going to start a thread to say that.Nubo said:You've noted that often Tom. But too many owners HAVE had 12V problems. I think it's strongly dependent on how the car is used. And the things that impact the 12V health and longevity aren't at all intuitive to the average driver. Meaning they have no reason to suspect or avoid them. So while your battery has performed adequately, either by happenstance or deliberate behaviors, other drivers have not been so lucky.
I agree that the solution is simple and Nissan needs to do something, since some proportion of the current batteries will fail under the current usage and charging regimen. There just isn't any reason not to fix this problem. Perhaps it is due to some sort of corporate inertia.A deep-cycle 12V battery is much more appropriate for EVs that have extra-curricular 12V demands*. Tesla discovered this and had the sense to switch over. Nissan still hasn't gotten the clue.

It was less about weight and more for performance. My family is an ACC vampire clan. Between the tablets and phones, cold weather, etc. My stock battery is only performing at 11ah, which is fine so far as the family uses the car everday. If it sits long enough I notice dim cabin lights when entering in the morning, that's what motivated me to look for this replacement. AGM replacement was expensive, so I figured why not just go full lithium. So far it has been flawless, no weak, flickering lights in the morning, don't have to worry about running the battery on ACC mode, etc.Slow1 said:I do have to wonder, however, if it really is worth the cost. I see that battery is listed as $260+shipping.
Saving 20lbs certainly isn't going to be noticeable on range. Do you expect that this battery will be viable for significantly longer than the stock battery? How many years do you expect it to last?
Well, sure but when I started seeing battery issues reported in 2012 I checked mine and it was quite low. Or, to put it another way "I'd never had a problem with it" But it was on its way, after less than a year. And the problem is compounded because a low 12V on the LEAF has lead to all kinds of weirdness, including braking problems. Ain't nobody got time fo' that! On an ICE, you're usually alerted to a weak battery by sluggish starting performance -- i.e. long before the battery is weak enough to cause electrical gremlins elsewhere.dgpcolorado said:But how many drivers have been affected?

Have you done a 20c test just to see what capacity it scores? Mine appeared to work fine on 11ah, but running on ACC could deplete it without warning. I don't know if the leaf protects from ACC over discharge or not? Anyone know, that is a good question?TEG said:Random data point.
I have a LEAF delivered in Apr 2011 w 30K miles, still on the stock lead/acid battery - no 12V problems (so far.)
The LEAF does not protect the 12 V battery from ACC use. Those who want to run the car's accessories while parked are strongly urged put the car in "Ready" mode. That will support the 12 V battery with the DC-DC converter and the traction battery pack.knightmb said:Have you done a 20c test just to see what capacity it scores?
