Where to buy 12 V battery online?

Bottom line, we need to know where Op lives. He may not have Advance near his home. Personally, I like the Duracall Ultra made by East Penn and sold at Batteries Plus. They always give you 10% off if you buy online for in-store pickup and it's free replacement for 4 years. But again, he may not have one near his home. I always try to purchase batteries near my home so if there is a warranty issue, I can get it taken care of.

 

Yep, often times the local Toyota dealerships have better battery pricing than the part stores. If I were Op, I would start there.

 

I don’t think AGM batterirs can be filled with acid, as the acid is saturated into the fiberglass mat. Neither seen hole on them to feel the acid.
Also it was quite some time ago when I got new battery not fully charged, but that’s definately something to check.

 

Factory seal on an AGM is different than a "customer seal".

In the US, most "mail order" AGM batteries can NOT be shipped with the acid in them.......so the holes are open, the mat is dry and the customer puts in the acid and snaps a semi-permanent set of caps on.

Just because you have never seen it does not mean that it doesn't exist.

 

I’ve learned again. In Europe when I order a battery I cannot open and fill it with acid.
I didn’t know this, sorry.
