I've got the Yuasa battery since 6 months and it's working flawlessly ????
I've got about 7 yrs on a yuasa wet battery for 79 flh. I've always had great luck with both harley and yuasa batteries.
I noticed that between 4ah and 5ah battery is little difference, but not much, 15% i would say. BUT 5.5 procore seems like 50% better than 4AH bosch battery and at least 15-20% stronger than bosch 5AH battery. When i say stronger, it is noticable in speed,strenght when i cut pellets, or drill concrete, or doing some 100mm or larger screws.
Energizer or Yuasa are good quality from my experience. I’ve had an energizer for 5 years now still running and my last yuasa ran great till I drained it to zero doing stupid.
I had battery problems and got a YUASA and had no issue since so I think they’re a decent brand (highly recommended by people).
I run a Yuasa in my 114 Streetbob. Best battery on the market.
I’m just pulling out a 4+ year old Yuasa that only started giving me problems about 2 months ago. Gonna try the $30 Mighty Max special this time since it seems to have some favorable reviews and we’ll see what happens. ????
New battery fitted and all ok for about 2 months, then same problem. Took new battery out (AGM Bosch S5 A08) and charged it on the bench, left it there overnight. Next morning its reading 12.2v.
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.
