Good but….

[This review was collected as part of a promotion.] The Stanley FatMax BC100BF 1 Amp Battery Charger & Maintainer for Lead Acid & Lithium Batteries is a solid product. It did an amazing job at charging up my battery that is dying one me due to not using my car in 3 months.
I want to start off with the Cons.
-I wish this was portable and rechargeable. Depending where your car is, you’ll need an extension cord to reach your battery. It took me a while to realize that it wasn’t portable or rechargeable.
-don’t have an on or off button. This confused me.

Charge level indicator and auto shutoff

[This review was collected as part of a promotion.] This is a very nice portable charger. I really like how it shows the charge level and has an auto shut off feature. In general it seems to work faster than other chargers I’ve tried charging my battery from empty to full in several hours. This is a very nice and versatile charger that will be very handy for years to come.

Jumpstarted Our Zero Turn With Ease
on October 28, 2025
Posted by: at0033_3115
[This review was collected as part of a promotion.] The Stanley Fatmax Battery Charger and Maintainer helped my husband and I jumpstart our zero turn lawnmower! The battery charger is light weight and has a handle to help with easy transport. The charger is compact and has a convenient LCD display screen. My husband and I connected the cord to the wall to charge the battery charger. Once it was charged, we connected the positive and negative clamps to the lawnmower battery. We selected the engine star icon on the LCD display and then waited for a minute or two. This allowed the battery to regain its charge. Finally, we were able to start the mower and finish the last cut of the season! I cannot wait to see what we need to jumpstart next. I hope I never have to, but am excited to see it work on a vehicle! Try this Stanley Fatmax Battery Charger to relieve a very stressful situation!

[This review was collected as part of a promotion.] My husband has been using the Stanley FatMax BC100BF charger for our car and lawn equipment batteries, and it works perfectly. It’s reliable, easy to use, and charges efficiently without overheating. The build quality feels solid, and it’s compact enough to store anywhere. It also has great safety features that give peace of mind during charging. Definitely a handy tool to keep around the garage, especially for maintaining batteries during colder months.

[This review was collected as part of a promotion.] If it’s not one thing it’s another, isn’t it? Amazing how somethings just happen and having a resource like this battery charger! It’s a turbo charge and other diagnostic features are what truly make this unit stand out!

[This review was collected as part of a promotion.] Very sturdy. Keeping this in my girls car because we never know what’s going to happen. Very light and not too heavy. It seems like it is going to work very well.
