Battery Bosch or Energizer

if you have a costco membership they sell the bosch batteries for a bit more but theyre amazing. 4 year warranty too

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.

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.

I typically use what is shipped with the packaging. Most of my red dots are trijicon and they ship with energizer so I will continue to use it. I feel the companies do their own testing trail and error with battery life and usage at all power levels under all temperatures.

Energizer. Better QC than Duracell imho.

I have used Bosch, Panasonic, and now Amaron in my 2013 WK2. Bosch lasted as much as my previous 2 Mopar lasted.

The mechanic I go to gives me Bosch and they last around 2 years if not more. But then they do die within a day when they do.

This is the worst battery i tried, Enegizer lasted less than a year, maybe around 6 months only and it started dying.

A few hours later he came back with a new S4 018 Bosch battery (original one was Yuasa HSB056). He assured me it had the same specs, despite being a different brand (40Ah, 12V). He installed it, and then told me it was a “slightly different base size” from the old one.
