Does Ridgid still have lifetime warranty on their batteries? I've found mixed info online.
They never had a "lifetime warranty". What they have is a "Lifetime Service Agreement", called the LSA. It's a big difference.

You have to register the tool, jump through several hoops of mailing them the receipt and HOPING they update your account to reflect it (or else it'll say "3 years warranty" and they'll deny they ever got your letter unless they make you a "one time exception").

Then, if a tool breaks, you must take it in person to an authorized repair shop of THEIR choosing. It was 1hr40min away for me. I can't afford to spend around four hours to take a $100 tool to them, then another four hours to pick it up. And that's assuming the repair shop actually did their job properly. You hear stories about repair shops losing the tool, not fixing it properly, etc. Ridigd doesn't stand behind them, so they just tell you to take the case to small claims court. For a business that's two hours away. For $100.

I don't know how they handle things if they no longer make spare parts for that tool. Given how they run everything else, you're probably up the creek without a paddle.

I'm sure if you live in a big city, you'll have a repair shop closer to you. Hopefully. Not all of us do though.

Sad truth is...warranties in the USA have no teeth, unlike in the EU and Australia. It's a "trust me bro" warranty here, and you hope they honor their word.

Yes. I've registered every battery I've bought including the ones I bought last year. I even recently claimed one of my original 3ah batteries that finally stopped charging after over a decade. They don't make a 3ah model anymore so they sent me a brand new 2ah.
Ah, so they gave you something less for the money you spent. I hope you didn't "let" them walk all over you.

It's much improved in the last year. Last tool they emailed me a shipping label, I stuck in a box and had FedEx pick it up and then 8 days later it came back all fixed!

None of that is true. You register online by uploading the receipt and if you need something fixed, they give you a prepaid shipping label to send it in.

I've never had a problem with a repair or replacement... fill out the form, they send you a label, you shove it in an Amazon box, and you get a repair or replacement in a couple weeks.

LSA has worked for me. HD gave me a much better drill with bats and charger when a 7 year old drill intermittently would stop working. And, HD said to keep the original bats and charger that came with the malfunctioning drill.

Absolutely no true, as long as you register your tool or battery correctly at the beginning , which includes providing proof of purchase by UPLOADING a picture of a receipt, when they first started LSA this was the case and it sucked but nowadays its stupid simple, battery replacements are seamless, you tell them which battery is bad and they mail you out a new one for free, tools have to be shipped or taken to an authorized repair shop

The battery was a decade old.
How many batteries will Dewalt or any of the others replace after over 10 years of use?

I have this tool. Surprisingly this is a brushless... even there is no "brushless" label on the tool. No spark, no smell when turn ON and OFF.

LSA was easy, the approval took several weeks. May be to avoid people registered their tools when they brought their toool then changed their mind and have them returned.

Doubt this specific one is brushless. Their brushed and brushless models look extremely similar.

There are several reviews mentioning it overheating or stalling out. Does anybody actually have this tool? I wonder what's drama versus reality with these reviews. I've never stalled an angle grinder of any kind in my life.
I just got home and mine arrived. Messed around with it a little bit without turning it on but I've got some really hard steel I'm going to test it on tomorrow. I will report back on what I think of it 🫡

It's back in stock... I had a 10% off mailer and need a battery model so went ahead and grabbed one. But it is 100% a brushed model. They have a Brushless model that will be slightly more powerful than this brushed model, but with the lsa it's not a huge deal and most of us got tons of batteries so more battery life on a Brushless model isn't a big deal
