Battery Bosch or Duralast

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.

Just a heads up I had same issue with my Titan and it was the battery. I purchased a cheaper battery and 6 months in I get only a click when trying to start truck. Sometimes would start sometimes not. Then I bought the same battery again to see if that would fix the issue. This time it didn\u2019t start at all with the same type of battery, tested 100% charge and 100% battery life. So I said let me try buying a better quality battery just to see if anything happens, sure enough the truck started. It has kept starting ever since.

I used euro car parts 444770127 which is a mid range bosch battery. Don't remember any issues

Bosch, m-a tinut 8ani. Acum tot bosch de 70/75am luat.

Duralast is a decent brand, I’ve always went with the gold, no real reason just that it’s what was in the car before.

my 2010 4x4 needs a new battery. This one lasted 4 years Duralast Gold.

The Bosch has slightly lower Cold Cranking Amps at 330 vs the Yuasa at 360. Also Bosch has 4 yr warranty vs Yuasa 5yr.

If you actually worked at AutoZone and knew anything you know the duralast golds are decent.

I bought a brand new Bosch battery last year ( not Halfords)and when I checked the voltage it was less than 10 volts so there are dud batteries out there.

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.
