My Optima Red Top is dying. :frown: I need a new OEM battery and wondering if anybody knows a good place to get it. Thanks.
ATERPAK said:Why would you want to go back to an old lead acid battery type when you had an Optima? The gel style battery should be a lot better at vibrations and other extremes faced with the NSX, so I'm curious as to why the change back to a battery which could cause your terminals to corrode and have to be maintained.

They sell Optima batteries (both red top and yellow top) at Sam's and Costco, too...allcoupedup said:I replaced my Red Top Optima battery with this one:

Don't bank on it - if you go below 10.5V kiss it goodbye.allcoupedup said:The Deep Cycle battery allows you to completely discharge the battery and recharge it to 80% capacity multiple times.
Excellent choices. Note that you dont want the straight MJ - you need a "T" version with the SAE terminals. MJ (Metal Jacket) is great if you are in freezing consitions - I got regular case myself. So T or MJT model. You can buy SAE posts as add-on accessory if necessary.temp said:I'm considering the Odyssey PC925MJ and the PC1200MJT as they are both group size 35.

Waht they're actually saying is you can discharge it to 80% level and recover - not what you are suggesting.
Oops. I mistyped that one folks. My original message was a little misleading (Thanks D'Ecrosse). I meant to type "
The Deep Cycle battery allows you to completely discharge it to 80% and recharge it to capacity multiple times." And I'm sure that over time that capacity window gets smaller and smaller. My original battery (Red Top Optima) was only charging to ~10.8V and it hardly had enough cranking power. That's when I threw in the towel and got a new one.
I guess experience will tell if I can "bank on it" with this new battery.
