Where Is The 12V Battery On A Gen5 HEV?

Oh, the XLE pic above is an XLE AWD pic then, and I see the screw hole now, thanks.

 

Which maintainer brand. How many amps is it rated for ? How long do you leave the car sit before starting it ?

 

You are worrying unnecessarily, as neither Gen 4 nor Gen 5 has any real 12-V battery issues. Every now and then, a few people have isolated problems arising from such as the new car sitting in the dealer lot for too long before purchased, car not being driven frequently or long enough, using third-party accessories, using the accessory mode, unauthorized modifications, etc.

Occasionally using a battery maintainer is a good idea. You don't need to permanently install it. Using it every few months is typically enough, also of course, always using it when the car is not regularly driven. Any Noco Genius will do. The 12-V-battery-management system doesn’t like to fully charge the 12-V battery; therefore, occasionally fully charging it using a battery maintainer will extend its life and/or reduce the chances of a low-charge battery.

 

I believe it is called BatteryTender. I told my dealer I wanted to maintain the battery, now that the car will be getting much less usage. and this is what they sold me. I don't know the rating off-hand. I have let it sit for at least four months, maybe longer, expecting the tender to do it's job. I have it wrapped, and it is a pain to unwrap it, just to charge the battery, which should be done through the device that was built to do just that.

 

Get the Noco Genius. You can get the cheapest, 1-ampere one. It safely charges the Gen 4/Gen 5 12-V battery for about two days about twice a week, repeating the charge/standby cycle indefinitely according to the battery voltage, when plugged in.

 

My mechanic says they won't even tell you where a fuse is located,
because they want you to pay the dealer to change it.

 

My dealer has a soda machine with no prices indicated. You have to use your card to find out that you just paid $5 for a can of Coke.

This is in keeping with the predatory attitude I've experienced there since day one.

 

Good to know—I won't spoil the plot twist on p. 452.

 

Thanks. I have bought the genius 5, per Paul's suggestion. I am attracted to the feature that allows a full recharge to a dead battery without breaking out my big charger. I'm not excited about installing it my self, though. Maybe I'll find a service shop that will do it for me.

 

by the way, can this be installed without losing all of the settings when the battery is disconnected?

 

Any charger will charge a dead battery. The problem is that you never want the battery to go dead, as it results in degradation and capacity loss. No charger can fully correct that even using the repair mode.

You normally don't install the Noco Genius permanently. You don't need to disconnect the battery unless you are using the repair mode. All you do is that you connect the red and black cables correctly to the battery or service terminals and plug it in to an outlet. Don't forget to select the correct mode unless the default mode suits your battery (flooded cell for the OEM battery, which should be the first mode light).

 

It comes with a mounting strap that mounts to any surface with 2 screws. I didn't trust the alligator clips, so I removed them, and used the ring terminals instead. There is a 10 mm nut on a stud in the fusebox that is live to the battery, which I connected to.

 

I want to use it to maintain the charge on a rarely used car. Of course I want to connect it perrmanently.

 

Thanks, I'll look for that stud.

 

This is gen 3, but might be similar:
