- Battery Tender Junior 12V, 800mA Battery Charger and Maintainer for Lead Acid and Lithium Batteries - Switchable Battery Charger for Powersports - 022-0199-DL-WH

A small Battery Tender that works on gel and lead acid batteries. The tender has an electronic circuit so it will not overcharge and damage your battery. When the battery is fully charged the tender turns off. If the battery starts to lose a charge it will bring it back up to the correct level and turn off again. Very pleased with its operation. Fast shipping and a nice seller.

Chart says 800ma doesn’t charge boats but I use 2 on my boat batteries for winter; works just fine. They’re regular car batteries. Use one on Deere tractor and works perfect. Good product for the price.

I recently purchased a battery tender, and it has exceeded my expectations in every way. The build quality feels solid and durable, giving me confidence in its longevity. It was incredibly easy to set up right out of the box, with clear instructions provided. I appreciate the smart charging feature, which automatically adjusts the charge level to avoid overcharging my vehicle’s battery. The LED indicators are a great addition, providing clear information on the charging status at a glance. I’ve used it on my car, and it has worked flawlessly, keeping the batterie fully charged during winter. One standout feature is the automatic float mode, which maintains the battery at full capacity without overcharging. Overall, it’s a reliable, user-friendly, and efficient product that I would highly recommend to anyone needing a dependable battery maintenance solution.

Lightning strike blew up the one I was using for my car that was in storage in my garage, however the one attached to my motorcycle was fine and was unaffected...just bought a 2nd Harley and this is what I hook it up to every time I store the bike in garage after a ride just like my other bike...the battery on my first Harley lasted for over a decade using this battery tender (the dealership couldn't believe it), in fact my car battery lasted for almost a decade before I replaced it using the car version and I have every expectation based on previous experiences that this one will do the same in preserving and maintaining the life of my new motorcycle battery...durable and reliable and they work!

Works properly with a 12V Li-ion battery. Yellow means charging, flashing green means 80%, solid green means 100%. Also works with traditional lead acid and AGM batteries. Backward compatible plug with old Tender Jr so no need to replace the old lead if you already have one wired in.

The Battery Tender Junior 800 seems to be well made but one important point is worth noting. This unit will not charge a motorcycle battery that is completely depleted (i.e., dead battery). You have to have a minimal amount of voltage in the battery for the unit to work and so you will need to have a larger charger. Once I partially charged my dead motorcycle battery the Battery Tender did a good job of bringing the battery to 100% and seems to be holding the battery at full charge even in the middle of winter. I like that you can disconnect the alligator clips and permanently affix the connecting cable to the battery.

Perfect for maintaining your car batter. This product is an absolute must for anyone with a low mileage Porsche that gets driven sparingly. My recommendation is to purchase the eye hook accessory and permanently attach those to your battery so you can easily hook this battery tender up whenever necessary without fiddling with the plastic shields covering the battery in your frunk. Take it from someone that knows, if you ever let your battery go dead without having your frunk lid open, you will have an extremely difficult time getting it open! I have owned several battery tenders over the years and highly recommend their product for the quality, ease of use, and reliability.

Works like it should, no issues. Delivered on time.
