Battery works

orr.... maybe its a good excuse to upgrade my battery ?

 

As mentioned. Clean it to remove battery acid. Wire brush. Here is what we used on all the DCV plant when wiring cell towers https://www.sanchem.com/electrical-contact-lubricant.html

 

Buy a new one and send Toyota the receipt. They reimbursed me 350$ for a new AGM lol.

 

wait what??!?!/ more details!

 

I sent them test results of my bad stock batter and a copy of the receipt and they sent me a check in the mail

 

¯\_(ツ)_/¯

 

wire brush the hell out of those terminals, put those battery washers on the battery posts and spray battery terminal protector on the top and bottom of those terminals. Cheap insurance. I've been doing this for years on all my vehicles and never ever get any corrosion. Yours might be too far gone though.

 

Good Idea!

 

Maybe this would be money better spent. I installed this kit, gives me plenty of taps for future connections. (picture from SDHQ)
