Battery OEM Toyota or Deka

I have a ‘24 RAV4 Prime and a ‘13 Prius V. I can say that my battery and fuel efficiency on both vehicles drops between 30 and 40% as soon as the cold weather hits. Range on the RAV4 Prime goes from 80km/charge to about 55-60km in cold weather, plus the gas runs more often so I don’t go as far on a tank (~1300km winter vs our record 2100km spring/summer).

I only use deka on my service rig. Usa made quality. Though listed at 540 CCA, MY Midtronics tester shows they output 650 - 750 CCA.. I easily get 7 years use in the field with these.

Deka batteries. I’ve turned wrenches for twenty years and they’re the only ones that still consistently test far above their rated capacity when new. I have one that’s 7 years old and just installed one in my other rig last year.

I did this accidentally and my car never stops at traffic. After 3 years the original battery died and I had to replace. I replaced with an after market battery that matches the ratings but not from Toyota dealer. Ooops all works fine except the auto start stop. it says \"incompatible battery\" but never shuts off at traffic signals.

Paid $350 US recently for a 12 volt for a 2018. Yep, I know that's a lot, but I was at the dealership getting routine maintenance done and it tested borderline. Knew this to be true and was carrying a jumppack. However, it's with a lifetime warranty. That sold me.

I bought a Toyota Truestart for $224 USD with taxes. Swapped it in the dealer parking lot in about 5 minutes, took the old one back in for the core charge.

My toyota battery from 2013 lasted 12 years. I hope my 2025 Hyundai battery can come close.

Batteria cambiata nel 2024 avevo ancora l'originale Toyota che m'è durata 15anni.

Assuming that it's a hybrid and not a PHEV it should run you about $2,500 to have it done professionally, or less than $1000 to do it yourself. At least that was my experience with my Prius.

Having been burned with low quality auto parts store batteries (specifically for the Prius) and their being unable to honor their warranties, the Toyota battery is the only way to go.
