Stanley BC209 Battery Maintainer

I am using this as a battery maintainer. Seems to work fine. It is a higher quality case and wiring than the Schumacher units I had used in the past. These are a buy again.

This appears to me to be the same BC209 as the more expensive all yellow version. This one is advertised as a maintainer but the directions and box refer to it as a maintainer/charger just like the yellow version. The paperwork is dated 2011 so it is a up to date model. I bought this to maintain my starting battery in my motor home while in storage which is most of the time. The "house" charger in the motor home only maintains the house battery (not the starting battery)so I was going through starting batteries way too fast from lack of use. The charger does exactly what I wanted which is slow charge then maintain the battery level. The included plug adapters are all nice quality. I chose to use the cigarette lighter adapter and it works great. The light indicates when it is charging and when it is charged. The unit runs without making any noise at all. I actually put my ear to the box and could barely hear a slight hum. From 1 inch away you can't hear a thing! Also there is no odor from the unit either. I could not be happier and highly recommend this product. Now when it is time to travel I can just start her up and go!

This charger works as good or better than chargers costing 5 times more. I bought 3 of them to use during the winter. Great value!

For anyone who has a vehicle which doesn't get much use, this is a must.

We have a valued, but seldom used vehicle which we would very often forget to start up and run. Hence, whenever we DID want to use it... dead battery and usually dead enough to need a new battery. It was getting silly and expensive. Finally, one honest battery salesman said, "buy a trickle charger" and we got this one. It is just what the doctor ordered. We still have to turn the engine over occasionally, of course, and keep the "juices" flowing, but no more dead battery and expensive replacements if we forget for a couple of months.

This is just a tiny little thing that has a magnet that attaches itself to the side of the car. You crack the window and feed a cord through to insert in the cigarette lighter slot. Attach an extension cord to the other end, plug it in the wall and it just does it's thing.

Love it!

Want Stanley BC209 Battery Maintainer Discount?

The Stanley BC 209 Battery Maintainer is one of the worse battery maintainers that I have used/purchased. The charger gets extremely hot, has wide range in charging voltages (13-15V), and for me, stopped working after 6 months. The overall design is basic and feels cheap.
