At 40k my stock battery decided to leave the chat while at a trailhead. Fortunately, I had my little battery jump starter. Highly recommend these for your tool kit, saved me twice now (once on a Tacoma).

Some general points on Battery replacement for anyone interested…

The battery is a DH7/94R

I bought an Optima Yellow top. I’m sure there are other options that are as good, better or cheaper. The thing I love about it is the handle! Dropping a 60lb battery in between cables and other items into the cradle is waaaaaay easier with a handle. It fit perfectly.

To replace the battery you’ll need 10mm and 13mm deep well sockets, a 1/4” ratchet and 6” extension. All included in your Raptor tool kit! A flat head screw driver could come in handy too.

There are 10mm nuts on the battery hold down bracket and the cable clamps. Two 13mm nuts on the hold down bracket. All easy to access.

It’s a little tight getting the battery out, but there’s ample room to come straight up. It’s just difficult lifting a 60 pound battery straight up in tight quarters up and over the fender without a handle. I’d recommend using a step stool.

The felt liner slipped right off the old battery and on to the new.

Once installed it seems that one should perform a battery management system sensor reset. This is easy to do and doesn’t require Forscan or similar software. The procedure is to 1) turn on the ignition, but don’t start the engine. 2) Flash the brights 5 times in succession, 3)then pump brakes three times. 4) You should see the battery icon on the dashboard begin to flash after about 10 seconds confirming the reset. I’m still not sure this is actually required, but I did it anyway.

The before picture, as you can see there isn’t a lot of clearance or room to get your fingers in to lift the 60 pound brick

The Optima and its sweet sexy handle. So much easier to install/remove!

And everyone needs one of these, it holds a charge a long time, but you do need to check and recharge occasionally. This need is directly correlated to the age of your battery and the distance you will be from a AAA accessible point. So easy to use and store.

Good info. Happened to me on the trail as well. That little jumper would been nice to have.
 
I'd be curious if anyone knows what the reset process you went through actually does? I've replaced mine and didn't reset a thing.... heh.
