And yet my 2008 VW had a Bosch battery out the factory ????♂️.
Fucking thing lasted 10 years or so though. So credit to Bosch for that one!
I've had good luck with Bosch (made by Varta iirc) and Yuasa.
Change the battery to a bosch one, I had this issue and my car does 600 miles a week for work took it to toyota and they just kept charging it then giving it back to die again the next Monday morning, they tried to say I wasn't driving it enough until they pulled up the service history (2020 with 54k miles) but they still wouldn't agree to replacing the battery
2014 Mazda 3, about 65k km.\n\n2nd battery only because I left the lights on one time a few years ago and needed a replacement. Nil problems otherwise.
I find that the Bosch batteries I regularly sell last 5-7 years or 5-7 months.
the IP64 battery cover can't close because the battery is too high, it should work no problem with any other 18V Bosch battery including the Procore 4.0Ah.
Good light though, it's really bright.
And heavy.
The OEM batteries are shit. It died around the two-year mark.
My battery died last July at exactly 2,5 year mark. Mazda OEM battery is a cheap trash and so are the replacements too.
After 7 sets of battery drains, I installed a new set and left it on a shelf untouched for a week. Turned on and dead. Made a warranty claim with Bosch to which their lazy troubleshooting reply:
Let me start by apologizing on behalf of BOSCH for any inconvenience this has caused you. I performed a complete inspection: I 1st charged up your lithium battery. I then calibrated & tested unit with both alkaline & lithium batteries: PASSED. I know it’s an inconvience. But: Leaving any batteries in unit when not in use: ( Unit will drain all battery types )—( Unit self discharges batteries when not in use ) --That is why Bosch put in manual tom remove batteries. PG# 21—Attached – ( they actually don’t say how long the “ extended period is “) That way it is not considerd a factory defect. Other than that: unit is operating to all Manufacurers Specification & Tolerances. Best regards,
-Well I'm never buying another Bosch product again with customer service like that. Pissed that I bought this expensive paperweight. What product in today's world drains batteries when not in use? Clearly flawed engineering they are hiding and do not value the end users. A recall is in order.
I switched to Bosch after that. that failed after 2.5 years, just under warranty. so it can happen with any company. some batches might have good quality some do not.
