Just been quoted £320 by lexus to replace a 12V.  I know from reading a few posts that the Battery in these aren't standard (Gel / AGM is needed).

Anyone have any recommendations for an after market Battery that will fit without having to mess around with the breather pipe and is safe?

Many Thanks,

Darren.

One might recommend you pay the £320 and have it done properly.

That way, should the very worst happen, they’d have no reason not to warrant a warranty claim or give good will if something more serious was to go wrong.

I would definitely wait for some more opinions.

For starters, I'd want to know why my Gel/AGM Battery requires a change after only 3 years, when a normal acid Battery will give more.

Unless it's doing something unique, the 12v batteries in Lexus hybrids normally only help transfer the electrics of the car to the hybrid.  Nothing special needed for that.

OOPS!  Just realised the header says RX450h.  I was looking at your details that list the IS300h, hence my comment about age of Battery.  The other comments stand.

With the greatest of respect - that's a silly statement and if you genuinely would pay that then one might say that you have too much money burning a hole in your pocket. It's not like you'd even be getting a 'genuine Lexus Battery' for that extortionate amount because Lexus don't make batteries!

It's a 12V Battery, nothing more, nothing less and it's an easy 10 minute job to DIY. Even if you don't want to DIY there's still no need to pay such a ridiculous amount, as the screengrab below from another topic on this very forum shows:

I did wonder. When I read this yesterday I looked on the Euro Car Parts site and prices weren't anything like. Even before you add the silly promotion discount.

I’m not sure you can ever have too much money ;)

the cost on the lexus website is £235. So don't accept the quote and ask them why it's £100 more? It was £185 on the website last year when I had mine done. I was quoted £235 (coincidently) and got them to price match the lexus web site. I went to Lexus Sheffield.

That's interesting, didn't know they put prices online. I've ordered a Battery online for £125 which I'm assured is a direct replacement AGM type Battery. Will post details if it's a straight forward swap. 

Well I'm happy to make and shame, it was Lexus Leeds that quoted me. I'd have let them do it for £235 cost.

Just found the details on the Lexus website including prices for other items thanks for that. 

Interesting just seen Leeds and Birmingham are owned by the same group and my experience of Birmingham with my IS left little to be desired (I actually complained to Lexus UK it was that bad).

Found Lexus in Leeds to be a little over priced to say the least, when I got the car from another garage it needed some work doing, Lexus Leeds wanted another £1000 over another Lexus dealer in Stockton, guess where it went.

Euro car Parts are quoting £118.99 for a new battery with a three year warranty

That still sounds a tad expensive, especially since you don't need the cranking amps that a conventional car requires.

Sorry to sound a bit dim but I've only ever been used to an engine starting by cranking with a starter motor. How does the engine on the 450h start if it isn't cranked by a starter motor ?

In a hybrid car the 12V Battery only powers the entry/exit system and it boots up the computers that are required to get the hybrid system into the READY state. Once there, the traction Battery takes on all starter motor and alternator duties.

The engine is spun up by one of the electric motors (MG1?) powered by the traction Battery. Massively more powerful than a traditional starter motor. IIRC it spins the engine up to the correct revs before the ignition actually starts.

That's a neat way of doing it.  I've never been in a hybrid, but this would make the combustion engine cutting in very smooth.  I've noticed the stop-start engines on other cars ignite very smoothly (most of them diesels).  Technology these days!

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
