5 out of 5 stars Show by Dec 23, 2020 Top favorable review reliable, fail-safe, longlived.this brand of charger has proven itself to be reliable long lived and easy to use.I use these chargers to keep antique car batterys charged over four-six months of wintertime and they always maintain a fully charged condition until springtime. The best thing about this charger is that you cannot hook it up incorrectly, unlike most chargers on the market! great unit to have. Verified purchase: Yes | Condition: New 2 out of 5 stars by 40flinterAug 03, 2021 Top critical review FED UP WITH DELTRANI used Deltran charger/maintainers for years but recently I have had to replace 3 of them that quit working. Two of them were a couple of the most recently purchased. I'm afraid that Deltran has gone down the same road as so many products. More cheaply made and higher prices. Going to switch to another brand in the future. Verified purchase: Yes | Condition: New Bought another one because I liked the first one.I bought this product to supplement one, just like it, that I have been using for the past 12 years. I have had good luck with the original charger, but I needed another. I hope I get the same performance from this one. Verified purchase: Yes | Condition: New IT DOES NOT GET ANY EASIER- GREAT CHARGER.Charger is very easy to operate and functions as illustated in manual. Follow instructions when " hooking it up " and walk away- it will charge to proper level and then maintain battery. It does not get ant easier. Verified purchase: Yes | Condition: New Much better than similar battery tender from Harbor FreightI use this to maintain the battery on a generator. Had it hooked up for a couple weeks now and it's working perfectly. Prior to this I made the mistake of purchasing a similar battery tender from Habor Freight. The Harbor Freight tender lasted less than 24 hours. I have it placed in the garage where the indicator light is visible when entering the garage. Good seeing that green light indicating the battery is at full charge. Verified purchase: Yes | Condition: New A Battery Tender charger is a microprocessor controlled fully automatic charger/maintainer. It is designed to extend the life of any lead acid battery commonly used in automobiles, motorcycles, ATV's, personal watercraft, RV's, boats, airplanes, golf carts, back-up generator systems, etc. Any vehicle or battery operated piece of equipment not used on a daily or regular basis is a candidate for Battery Tender charger. The advanced technology will bring your battery back to a full charge
without overcharging and then float or maintain the battery for an indefinite period of time.
Can a Battery Tender jr charge a car battery?STAY CHARGED
Designed for use with powersports, it can even assist with automotive vehicles!
Can you leave Battery Tender Jr on all the time?Both the BatteryTender® Plus & Junior battery chargers do not turn off after they charge the battery. They automatically switch to a safe float voltage level that keeps the battery charged and yet does not do any harm to the battery.
How long does it take a Battery Tender Junior to charge a dead battery?The Battery Tender® Junior charges at a rate of 750mA, or 0.75A per hour. Therefore, a fully discharged 15 Amp-Hour battery will take approximately 16 hours to recharge to 80% capacity.
