I've got a Batteryminder Plus 1510 that's on a RAV4 Limited and I haven't seen any issue with it.

 

I used the CTEK MXS 5.0 on my '21 Venza during the pandemic after the battery went dead on me, comes with direct connection hardware, worked well.

Thanks. I'll check that one out.

 

I’ve been using a Battery Tender brand for 13 years with my Miata, no issues. Since I store it all winiter I do disconnect the battery from the car before I hook it up. Not sure if that makes a difference or not, but just in case the maintainer does something stupid it won’t hurt the car electronics.

 

I'm just worried about the vehicle dumping all its memory with the battery disconnected. I'd think that could cause issues from the car having to re-learn driving habits to something more severe.

 

Hello all, I was wondering what a good battery tender type device (or would that be a battery maintainer?) that works well and is safe for our RAV4s. I've had a medical issue/surgery and probably won't be driving for a few months. I'm just concerned if those things work as normal as they always have or if there's any additional concerns with such a modern and electronic vehicle. My last vehicle before my RAV4 was a '99, so I've been out of the loop on this stuff for decades. LOL

I'm just looking for something simple to keep the battery from discharging and getting killed. Thanks!

i like this charger
and then extend the power cord out the front grill with a custom cord.
and if you like to have a block heater you can make the cord as a Y cord to power both with one front cord.
i plug in all the fleet cars and trucks after use for the day.
that way i always have a good full battery charge at the first run of the day.
and they help extend the battery life as well.
the last battery in the rav lasted 10 years! no kidding.
the charger did that for sure.

 

Wow, 10 years. That is impressive. And, nobody believes me when I got 8 years out of a battery in northern Arizona with blazing summers and freezing winters. LOL

 

Battery Tender brand
Got two of them and buy a pig tail to install on the battery on all my vehicles (need to get one for my new-to-me Rav)
Great products, reliable and keep your battery from dying.

 

I thought Battery Tender from the get-go because I've used one many, many years ago. Which unit would you recommend? There's several different ones on Amazon. And, safety is a huge concern, too. I don't want the thing lighting off and causing a fire or something. Thanks!

 

lol we do it in Iowa.
105 F summers and -20 F winters.
let alone the wind chill and thermal under the hood temps.
if you take care of a sla or agm battery they will last a long time.

collision tears them up breaking the internal plate mounts etc.

 

Word
Well, again, they're (those plug-in kits) great for mowers, motorcycles, really anything with a battery!

Shop around, Battery Tender stuff is on sale somewhere all the time

 

Thanks again so much!
