Re: Flashers for 2 Hrs Kills 12V Battery

Queue endless battery recommendations...and links to LiFePO4 replacements (see sig).
It would help if you added location to your profile; depending on where you live 3+ years on any lead acid battery could mean it's time for a replacement (especially in a Leaf, where a weak/dead 12v battery can cause so many problems).

Re: Flashers for 2 Hrs Kills 12V Battery

I live on the coast in Northern California (95570).

Can I do a load test myself? That is,

1. Measure voltage
2. Turn on lights in Accessory only mode for x minutes (e.g. 120 minutes)
3. Measure voltage again
4. If voltage has decreased by y percent, battery should be replaced.

What would you recommend for the values of x and y?

Thanks.

Thanks, guys. I think I'll have the batter load tested, and if it's not up to snuff, I'll replace it.

Please recommend the best battery under $200 (exact model).
Don't know if it's "the best", but it's a pretty good AGM battery, it fits without any modification, and it's got a great warranty (4 years full free replacement). $146 at Pep Boys

I installed this 8 months ago, in my 2015 LeafS, 28k miles. So far, so good...but it's only been 8 months!

My '15 SL, 18k miles, Boulder, Colorado, is on its original Michelin Energy Saver A/S tires (soon to be replaced) and its original 12V battery.

Should I pre-emptively replace it since a flaky 12V really causes conniption fits?

The only AGM I've found in my area is this one:

If it isn't more than the $195 it is in my area, it should be fine. As I wrote, anything labeled AGM should be ok as long as it isn't a fake.

Here's an Exide that Home Depot carries. I'd wager the Bosch is actually a rebranded version of this Exide battery. A little cheaper than the one you found and also has 4-years free-replacement warranty vs. 3-years limited.

I noticed you're still working with polymers.
