    Battery Tender Works Great

    Customer review by nascaryankee

    5.0 stars by nascaryankee

    I have been using an old Sears manual charger for thirty years. I could not tell if the battery was full and always had to watch the manual charger in order not to overcharge. The Battery Tender is great. The red light shows it is charging, the blinking green shows it is 80% full and the solid green light shows when it is full. When the battery is full, it goes into a safe float mode. I have used the Battery Tender to recharge my new batteries once a month in my two daily drivers. Plug in the evening and by morning, both are full and green. I drive short trips at night in winter and the cars does not have enough time to recharge the batteries. The Battery Tender is good for recharging batteries safely. Recharging may take a long time with a new battery or big battery.

    I have been noticing Battery Tender products for several years and I always considered them to be overpriced considering similar competing products. Regardless, after reviewing other chargers I bought this one. Well after receiving it I used it to charge three of my smaller batteries. It worked very well, indicated charge status throughout the process and entered the Float/Maintenance charge status at the end of the main cycle. It is made completely in the US and I have to say that despite the almost double price compared to other automatic chargers I am completely satisfied. The unit has a very compact, well built, US made feel to it. I have no regrets and do recommend it to anyone who wants to charge smaller batteries (Lawn Tractors, Motorcycles, and similar sized batteries) with no reservations.

    My husband said that it has already paid for itself! He wanted it to charge the battery on an old pickup truck. But then he also found that another vehicle we own had a dead battery too. So he was able to recharge 2 vehicles. This product really works.
