CUSTOMER REVIEWS

Rated 4.8 out of 5 by 33 reviewers.
Rated 5 out of 5 by Terrific unit I found myself in a situation where I had to store my motorcycles remotely, while I moved cities. At home I used a an ultimate unite that I swapped between 3 bikes, but with a move I had to store the bikes a 2 hr drive away for several months and I had to find an alternative, reasonable cost solution. The ultimate is a great device also but way more costly. I decided to order two of these B&D units as I have always been happy with their products. I researched the background and figured if B&D bought the company that designed these they must be OK. I hooked up two of my bikes with these units and left them for 5 months alone in storage hoping I would not need to buy new batteries when I got the bikes out. When I got back, the green LEDs were illuminated on both units. Turned the keys and both bikes started up like champs. Batteries were strong cranking and kept fully charged. I have since moved the bikes to the new house and these units are on them constantly while we endure winter in the east. really really satisfied with this product. At 20 bucks each I already exceeded the value from them in saving me over $200 cost in new bike batteries. They saved me in this storage and now are holding me through winter. Enough said!!

Rated 5 out of 5 by Awesome I used it on the back up battery I purchased for my 4 wheeler and it did a great job of maintaining a charge on the battery. October 22, 2014
Rated 5 out of 5 by Frankenstein Like Frankenstein.... This trickle charger brought my battery back to life. It's easy to use and works great. I purchased this for my Toyota land cruiser which hardly gets any use. And every time I need to take it for a drive it starts without fail... and for the price... you can't beat it. August 29, 2014
Rated 5 out of 5 by DC Residential Lighting System Our home has built-in 12vdc LED lighting in most rooms that operates from a large, central deep cycle battery. It can operate our house for about a week before needing to be topped off (typically @ 70% charge). The battery was rotated with another one in our solar powered workshop and recharged away from the house. A minor hassle - but worth it for clean, bright Off-Grid illumination. Attaching this BM3B trickle charger to the central battery has made it in effect a Uninterrupted Power Supply - keeping the voltage close to a healthy full charge at all times and eliminating the weekly switch-out. And when the grid goes down for an extended period (as happens in our rural area a couple of times a year) we still have the solar recharge option. It installed very easily. Took a few hours to top-off the deep cycle - but went into float mode overnight and kicks back into trickle charge mode for a few hours after a night of using the lights around the house. Its case gets slightly warm when charging. Expected. Mounting screw holes are very useful in our application. I agree about the 6v/12v switch feeling a little cheap - it needs to be more "clicky" to instill confidence that it won't easily/accidentally be knocked into the wrong voltage setting. Only thing yet to be proven is it's long-term serviceability. Here's hoping - it's a very simple and elegant solution! February 15, 2014
Rated 5 out of 5 by Keeps it charged I have 2 of these and use it to keep my quad and jet-ski batteries charged. Light on unit will tell when it is fully charged or is in the charging state. Has different type on connections where you can permanently attach an end to the battery and have a quick connect. August 28, 2014
