There is only 1 Aux 12v Battery replacement = Optima Brand?

have you tried sears, auto parts stores or batteries plus bulbs?

 

I'm not sure if it's the same battery as regular 3rd gen Prius, might well be. There's several options:

The stock battery is a Yuasa, believe the dealerships should carry that, though it's getting overly expensive, over $270 a couple of years back when I was looking.

Canadian Tire carries a rebadged Exide, at least for ours, under the name "Motomaster Eliminator Ultra AGM"

I went with the Optima Yellow Top, coming up on 2 years back. Amazon has it, but AFAIK know they're actually coming from SaskBattery. That's the route I went, it was maybe $10 cheaper, it was shipped for free (no small task), well packed, and they only charged GST. I hooked it up to a smart charger before install.

Next time around, I believe I'll go the Canadian Tire route. I had a recent experience there buying a battery for another family member's Honda Civic, and the Can Tire battery was physically identical, just rebadged to Motomaster, their house brand. They had a pro quality electronic load tester on hand, and were quite willing to check it status before selling to me (it was fine). There's a $20 core charge, refunded when you bring back the old battery.

My notes, and again, this is for a regular 3rd gen Prius, might be the same:

Any S24B24R group/capacity/size/format battery will work. Some prefer to stay with AGM. They come in sealed and vented designs. Be sure to hook up the vent tube on a vented battery.

 

I buy a Yuasa YBX3053 lead acid3 months ago and works fine. Have the same size, the same specs and is more cheap (75euros).
Why buy Agm? 3 or 4 times more expensive and life time isnt so different. ( lead acid 4-6 years vs agm 5-7 years)

The original was AGM. What you bought is SLA and has reversed posts.

 

Correct Air Boss.

 

Spill-proof in accident, or no? Plus venting into the cabin?

 

Yes it's spill proof ( it's secure inside the car) and have a vent pipe like the original.

 

I've been using this for 3 yrs. in October. Didn't have to modify the cable ends, just removed the bolt and inserted the battery post and replaced the bolt. I used a one and one half inch piece of wood under the hold down. The battery is sealed, no vent and no spill in any position.
