battery life/alternatives

[goldNSX]

Hi
My battery is 3 years old and seems to die. The water level is low. How long does your NSX battery live? Are there any lighter alternative to the 60 lbs. battery which lasts for three or more years and is appropriate for a weekend driver?

Greetings,
Thomas

Thomas,
I just changed over to this one only 14lbs and cranks like crazy. I also picked up the Dali battery mount fits perfect.

When my battery fails I will get one of the Oddsey ones.

As a side note, you can get the same battery (but without the Oddsey label) for a lot cheaper. Hawker batteris makes the Oddsey batterys but cost less.

Here is a link to both:

Great pics, Steven! Thanks, I like it.
The OEM 60 Ah battery needs to be recharged after 2 or 3 months or so. So the 17 Ah are only good for 3 to 4 weeks if nothing is done against the 36 mA drain. How long does it take the recharge an empty battery while driving at 2000 rpm. With climate control, stereoa and lights on, above what rpm will the battery will be recharged, below what rpm decharged?

Greetings,
Thomas

interestingly I just replaced my battery as well, I put no maintenance battery in that has a 2 year guarantee, and i've also just put my car away for a couple of weeks ..and i was wondering whether key locking the car instead of using the alarm to lock, may save some battery juice [alarm not req'd as car is stored in secure lock up]. Key locking the doors [auto locks] it doesn't look to have activated the alarm as the led hasn't lit up...am i right..I do know to disconnect the -ve terminal, but as the car is to be locked up for a short time I thought i might try the above without having the alarm armed and draining...

Does Dali sell the actual connectors. Mine are warn out and loose on the posts of my crappy battery. Time to get one of those with the bracket. There is no end to mods for this car. :biggrin:

How long does your NSX battery live?

I think the key to battery life is keeping it fully charged. I keep my battery charged; any time the car sits unused for more than a week, I plug in my on-board charger ($26.99 here).

I replaced my stock battery after six years. It was still holding a charge just fine. I replaced it as a preventive measure, so it wouldn't die at an inconvenient time. I have no idea how much longer it might have lasted.

That was seven years ago. I now have the battery that was sold as the Black Panther and is simply a relabeled Odyssey, so that battery is still working fine after seven years.

Sort of (but you can't tell that from the link you provided).

The Odyssey battery is made by a company that is now called Enersys, Inc. and was formerly called Hawker Energy. (I don't know if that was due to a simple name change or a merger/acquisition.) Enersys makes two similar lines of batteries, one that is sold under the Odyssey name and another that is sold under the Genesis name.

Here are links to various websites:

Enersys corporate website
Genesis battery factory website
Odyssey battery factory website

Here is a link to another, very useful website that did a comparison of various batteries and talks about which ones are equivalent to others, and which ones cost more than others: http://www.stealth316.com/2-dynabatt.htm In a nutshell, it says that the Genesis costs less than the Odyssey which costs less than the Black Panther which costs less than the Dyna-Batt, but they are all the same or similar.

Thank you guys!
I still have a final question: If I don't use my NSX for short runs (less than 2 miles) is there a probability that the battery drains out?
With lets say 48 mA the 17 Ah battery is empty after two weeks!

greetings,

Threads like this are the reason I'm rapidly becoming addicted to this site.

My NSX is going on 7-years old... original battery. It's still cranking strong but I know I'm on bought time.

Great info.

If you ONLY use your NSX for short runs, it's quite possible that the battery will drain. A lot of current is used in starting the car, and it takes a while (10+ miles?) for the alternator to re-charge the battery. This is no different from any other car...

I can promise you it will go soon :biggrin:

Mine (98-T Blk/tan production 092) died today, and I was expecting it as the cranking was getting weaker. Tracking does put a toll on the battery. After reading all the choices, I was inclined to get the Odyssey for weight saving but after considering the need for a new seat, etc, I ended up with the Optima from Battery Plus at the same $99 that Costco sells them for. And no disposal fee. YMMV but I doubt it :wink:

Let's assume that the starter requires 240 amps during cranking and takes 5 seconds to start. That's 1200 coulombs of charge. Now assume that during driving, the alternator is providing 5 amps to recharge the battery. At this constant charging rate, it would take 240 seconds (4 minutes) to replace the lost charge.

I have very little electrical expertise, but the store said this when we were comparing the cold cranking amps (CCA) of the Odyssey 1200 and the Optima 35/740 (I think that is the correct designation).

The rated cranking of the Odyssey is higher than Optima for the initial 4 seconds but thereafter it is lower. The Optima while rated at 740 CCA, apparently - and routinely according to them - shows a CCA of 1100 when digitally tested ..... not that this was the determining or selling point for me. They had both in the store.

By the way, my dead battery was putting out 240 CCA after they jump started it and it ran for some 10 minutes; so it appears that 240 CCA is not enough to start the electrically stock NSX. YMMV.
