longer lasting battery
I use Bosch 12 volt tools a lot in my shop and outside. This battery last longer so I don't change batteries as often. Great battery. Should come with tools.

Good Addition
I bought the large capacity battery thinking I would need it for a wooden fence project, but to my surprise the 2.0 amp batteries that came in the combo kit would have been enough to get the job done. I used the 4.0 amp battery during the build one day just to give it a try and because I bought it so I may as well use it. The battery is well made as all Bosch products are and I am sure it will come in handy on future projects.

Must have
These batteries are fantastic. I started a project using the oscillating tool cutting siding with the 1.2 ah and got a little bit done, not nearly what I needed. Next I switched to the 4 and it never died. I was able to finish making the cuts I needed for the day and then some. When used with the drills I haven't been able to run one dead in one day's use granted I am not going 8 hours at a time building houses but for the average joe using the Bosch 12v series these batteries are a great step up from the others. Not to mention the standup ability whith the big base.

Great for the 12v Max drills
I have two of the 12v Max drills, one has the impact feature. This high capacity battery will make these great drills even better. The drills will be able to sink even more 3" screws, tighten more bolts and drill more holes. Plus the battery bulge secures the drill in a belt hook

A Must Purchase!
The little batteries literally last FOREVER and quickly recharge if you, by some miracle, can discharge one in a day! Apart from the battery life, the best feature has got to be the ability to stand the tool up on the battery like the larger tools.

Great Power
I have had this battery for a few months now. I don't use my 12v tools daily but when I do its all day long. This battery lasts forever! It seems to give the drill and impact more power too. I will be adding a couple more of these as my 12v lineup grows. The other thing that I really like about this battery is now my drill and impact can stand upright.

The Battery
The BAT420 makes all of my 12 volt tools more efficient. More power is always a good thing! The drill and drivers stand up on their own, using the battery as a base.
Love it! Bought two!

Hi,
Will this battery work in the Bosch PB120 12 volt Radio?
Thanks
Ted on Jun 24, 2016
BEST ANSWER: I’ve NOT tried this in the particular equipment you’ve stated … but I DO know that the form and function of this batter SHOULD allow that. Only question might be is as to where the battery actually fits. If it’s an OPEN spot for a battery then the answer SHOULD be YES.
Do you ACTUALLY have this thing is stock? If you STILL don't, why not become customer oriented and put a NIS (Not in Stock)? YOU cost me $20 this last go around by my ordering over $100 in product and then subtracting it on the OTHER side by refunding me $40 on the battery since I didn't make the "over $100" when you couldn't produce. NOT good business practices!

BEST ANSWER: This item is a direct shipment from the manufacturer.
Is this compatible with the PSJ120Jacket? Does this include the charger? If not, what is the designation for the charger? I'm thinking of getting the jacket for my son for Christmas and am confused as to what else is required to make it operate efficiently/properly.
mom on Nov 16, 2013
BEST ANSWER: You will need a 12 Volt battery and charger, along with the jacket. Here is the model number for the battery and charger. BSHNSKC120-102
