Battery Deka or OEM KIA

I'm using Deka. But it's a good choice. I haven't any problems with it.

Deka batteries are still good quality. They are somewhat harder to find than other brands.

Fall 2016 Update: I just installed a new battery. It is a Deka Group 47 AGM. Cost was about 135$ at Battery Mart, 20$ more than the standard battery the store offered. It is odd in that the carry handle is square to the battery length. The specs say it weights 37-1/2 lbs. 600 CCA at 0 F. Two minor things: The battery foot flange is not thick enough to match the battery holding channel or the holding clamp. Some sort of wedge needs to be used. There are probably height adapters or spacers sold for that. Second, the hood release cable will need to run on top of the battery corner, unless you slide the battery out toward the radiator more than I want to.

I've been buying Deka batteries for awhile now and they have been great to me as a customer.

I just ordered a Deka EXT20L, from what ive read everyone loves it. At $87 from Lowes its worth the gamble. Its a sealed AGM battery so it can be mounted anywhere, ill be putting it under the rear seat.

I have personal experience with with both battery technology and the litium ones put the conventional small battery to shame. If I left my car with the small Deka that's in it for a few weeks without starting, or turning off the cut-off switch, the alarm and small draw I have from a wacky door switch would completely drain it.

My current dead battery is a Deka - lasted 3.5 yrs, can't complain.

Me too. Using a Deka ETX20 right now. Scooped it for $85 shipped from Tri-State Battery. I just got my car back on the road, so I haven't seen how well it holds its charge without running the car every day though.

Another is that the OEM Kia battery just sucks…they fail. The fix is to get a new battery that doesn’t suck. Kia will replace the dead one within warranty but you’ll get another dodgy OEM battery. Most people seem to trend towards buying a good AGM aftermarket battery for this.

Well it's 30 months old and is still 6 months under the pro-rated warranty. Took it to a dealer, they replaced it and said it would be 226 dollars! I asked if they checked the warranty and the technician stepped away and came back 20 minutes later. "kia corporate declined the warranty on your battery".
