2010, 2011, 2012 4runner Dual Battery (Tray$25, no Power Steering Reservoir relocation, no drill)
Dear 4runner owners (2010, 2011 and 2012),
I took a research in the forum and found that there are some modifications for dual battery. Those tech/professional guys choose the ARB or tailor made a battery tray, relocate Power Steering for the project. It would be a little bit costly or may void warranty of your 4runner, not too many people capable to do.
I would like to bring up this project to those people who want to add the 2nd battery but you are not an expert in auto or mechanical stuffs. Please share your thoughts so that we can go through this project together.
Here are the objectives for our group discussion (if you want to join up for this project) :
Requirement:
1. Add 2nd battery (exactly fit into your 4runner under the hood), sufficient to supply power for normal duty use (e.g. light bar, sound, mobile device charger, jump start for emergency….)
2. No modification or drill under the hood (e.g. you do not want to relocate or modify the Power Steering Reservoir…, except run power cable through the firewall).
3. Minimum cost (battery tray, battery, battery isolator, power cable, fuse….)
4. No fancy operation required inside your car compartment (battery monitor, manual switch…), no drilling in your dash.
5. Simple cable connections of the battery isolator, simple operation for jump start.
6. Assume you are not an auto expert or mechanic tech guys (same as me). You do not have too much knowledge how to choose a battery tray, battery isolator… You may not even know too much how to use a screw driver properly.
Steps:
1. To start with, I target the battery Odyssey PC1200 ($220) which is also used in other threads of dual battery system of 4runner. It is small size and provide medium power, should be sufficient for most of the applications.
2. With minimum cost investment and lowest risk to verify if this is feasible, I have to find a battery tray to see if it can fit into the 4runner. I found a battery tray ($23) in Ebay which can fit EXACTLY under the hood. Yes, $23 only ! The supplier can modify the tray (make it compact, the lid bends upright, see photos below) without ADDITIONAL cost. This tray is thin (width X length X height) enough to fit into the slot ! No need to spend hundred dollars for the ARB battery tray !
3. Your initial investment is only $23 to see if it works before you proceed to buy those expensive items e.g. battery, isolator….
4. The challenge would be how to drill 3 holes on the base of this battery tray so that it can exactly mount on the empty slot. Stop here and think about it before go further.
