It seems the stock battery is finally giving out, on my 2013 Infiniti G37 coupe.
Are there any good or bad battery options?
Maybe at least something with more power, then the factory stock battery?

 

I hear the Exide 24F from HD is a little beefier/bigger and good ffedback from members here: https://www.myg37.com/forums/general...ry-help-3.html

I actually just got an interstate from Costco since it was about $20 cheaper and my local HD was OOS on the exide - I had a bad cell, so couldn't really afford to wait.

 

this ... if you can find one. 800CCA for close to half the price of ones with 650-700CCA when i was researching them.

 

Right now the Everstart MAXX 24F, sold by Walmart, seems to be a good bargain and value.

 

 

I just installed (20 minutes ago) the (Walmart) EverStart MAXX-24F in my 2013 Infiniti G37 coupe.
I've have not seen my car start up so fast in years, WOW.
So two thumbs up for the EverStart.

 

I can also recommend the Everstart Maxx. It gets high marks from reviewers, and there's a Walmart anywhere you might need one for warranty service. The Warranty is the best reason, however. These batteries don't seem to be built any better than the others, and can fail like any other, but the 3-year no charge warranty is excellent, and it is pro-rated after 3 years up to 60 months; I've exchanged batteries many times within the 3 year window, so at least I always know I'm good for another 3 years without additional charge. The only problem then, which I've had, is that sometimes they are out of stock, but there are 5 other Walmarts that I can check with locally to get the exchange. One other caveat: These batteries require sufficient fluid levels; in the severe West Texas heat, levels can drop. and it's easy to forget to check the level regularly. If you start to have hard-starting, check the levels first, and top them off with distilled or demineralized water. One tip I saw was to equalize all the cells to the same height by using a batter tester or clean syringe to remove some fluid from the more full cells and adding to the lower cells, and then adding electrolye purchased from an auto parts store to bring them up to the correct level. Remember, when looking into the cells from above, the fluid surface should look slightly cupped; a flat surface means more fluid is needed. Charge the battery using a dedicated charger, or take a long drive to let the alternator charge it, and you should be good to go.

 

A while back my battery was giving out. Canadian tire Motomaster brand battery (700CCA, tested at 1000CCA by me) started my car SOOO much faster than it used to!
Working at a parts store has its perks! Got 10% off $140CAD, so not a bad deal!
