Battery OEM Toyota or OEM Audi

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 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.

As someone who bought their first Prius V (Lithium Ion- Australian Model) in 2013 No issues with any degradation in battery from 12 years ago.

I drive a 15 year old gas powered Audi Q7. Still runs like new. My issue with EVs is you can't just keep them tuned up when they're old. No matter how good of care you take of it, the battery will decay and lose capacity.

I have a 10+ year old Prius C that had a 100k-mile warranty on the battery. It failed at 108k and cost $4k to replace. It's at 230k miles now, and I expect to have to replace it again (but who knows?)

Spouse has a 2021 etron, (some issues, inc battery recall), I had a 2022 etron with many issues which prompted my change to a 2025 SQ6. I’ve written to Audi Canada so many times regarding the etron issues with no resolution on any of them. I like the SQ6 but this will be my last Audi - worst experience I’ve ever had with any vehicle and manufacturer.
