+1 Optima Red top and some KY to get it in... When my timing belt slipped and car was being diag'd we must have tested and hit the starter at least 100 times - battery held charge entire time.. Good time to add a battery quick disconnect too.

 

duralast gold in the trunk. works fine i guess
car always starts, no complaints

 

stock 10 year old panasonic... I actually had to replace the engine before the battery.

 

IS there something wrong with the batteries they sell at mazda i dont know about? Mine has been great.

 

I don't think Autozone sells the AGM battery anymore.

Advance Auto Parts

Autozone

O'Reilly

I think the OReilly one might be AGM though.

 

It used to be that mazda didn't sell the AGM battery (what comes with the car at the dealership) - not sure if this has changed but extra cranking power/longevity never hurts. Although my stock battery did last 7 yrs !

 

find someone who parts out miatas and pick up a battery from them... that is what I did.

 

They don't sell the Panny AGM anymore. Now they have a flooded cell. Which, in reality, is probably going to be fine. People act like the trunk is going to explode or something if a battery vents a little in it.

 

I had a non-sealed battery in my Miata for years with out any problems. It was vented via a little hose going to the bottom of the trunk. It was branded Mazda and came from a dealer.

I now have a sealed battery from the local battery recycler. All is good.

went up $5 to $85 + core.

holy crap that's expensive...

 

i have a oem honda civic batter (my cousin was a civic guy when i sold it to him), and have run it dead 6-7 times thanks to shitty autozone alternator belts and damn running lights

 

this thread is a ******* year old.

 

not for a few more days.

blame tonyc.

but did you ever decide on a battery yourself?

 

duralast. the one in the miata has already outlasted my previous 2 optimas at 1 year...and I rarely drive the miata so it charges and discharges constantly.

 

leave a tender on it, or take the battery in the house and put it on a tender. they're like $15 at walmart.

 

$6.99 at Harbor Freight...best I've spent. Who knows how long I can nurse this 9-year-old battery.

 

I forgot to close the door on my car last friday night (horray beefeaters&Tonic). Went to get my laptop out sunday night and saw that the interior lights were on all weekend. Car started right up no problems w/o a sign of drain.
