Battery Tender 4 Bank 12V 1.25A Smart Battery Charger & Maintainer for Motorcycles, ATVs, Lawn Mowers - Automatic Charging for Seasonal Vehicles & Power Equipment Storage

I’m not sure why the description doesn’t list car batteries first. Almost seemed like it was shying away from mentioning automobiles. I hope there isn’t a reason for it. I have the bank tending to a Cadillac, Trans Am & a Harley simultaneously. All’s good so far!The charger is small, lightweight and very well built, which is not often the case. The charger is perfect for charging the rv batteries in the off season.I like how easy this is to use. No dislikes at this time. Perfect for me. I use this to keep the batteries for the winch and generator in good shape while sitting dormant for long periods of time in our race car trailer.It is a very good productI love using this for my boat batteries. Seems to have extended the life of both of them (at least beyond what I was expecting).The maintainer worked well initially and did exactly what it was supposed to. After about 19 months two of the banks failed to power up or do anything. I checked that they were receiving power and that was ok. I contacted customer service, they were willing to have me send the product in for repairs under the 2 year warranty. That unfortunately did not suit my timeline. I purchased another manufacturers product.This is the second one of these I have purchased over the last 5 years. It works great. The first one I bought is still working too!6V, 12V, flooded, AGM, even Lithium. This unit does it all!OverviewI use this to keep the batteries in top shape on a pair of motorcycles. I have the quick connect harnesses on the batteries…no hassle with access and alligator clips.I no longer remove the batteries in our beautiful Ottawa winters…and have never had an issue even with the bikes sitting in storage for the entire winter.The cost of one lost battery is more than the cost of this tender…with the optional quick connect harnesses.Pros• Fool proof• No more lost batteriesCons• They should include the quick connect harnesses. I’m sure the vast majority of people do/will use them.Recommendation – Would buy it again and would highly recommend.<---Click below if you found this review helpful--->Se supone que o es lo suficientemente poderoso para cargar una bateria de carro desde cero, sinceramente no he comprobado eso, pero es algo a considerar cuando se obtiene. yo la consegui para mantener la bateria de un auto y la de una moto y lo hace perfectamente bien. A pesar de haber dejado de usar el carro mes y medio no tuvo nigun problema de encendido cuando lo volvimos a usar. Es muy versatil para tu cochera y si lo recomiendo.The product name Tendering. Sorry, lol. Between our best friends (in our bubble) we own 6 sleds, lawn mowers, and generator batteries. We winterize and tend to everything. Right now there is 5 batteries hooked up now. My first question is, why did the info that came with it said, weight 13 books, and only 6 battery hookups came with it. This tender came with everything, all ten hookups. It is well worth the money. Right now being well used, and will continue to when we summerize our snowmobiles. thank-you.I have a boat, a side by side and two ride on lawn tractors. Four batteries being taken care of at the same time without having cords everywhere. Great charger and battery maintenance unit for multiple batteries all at the same timeIam a snowmobilier and it's awesome to have the unit charge 2 machines at once.unit is light weight and at night when we are up north at -30 nice to know machines will start in the trailer since they do not have pull starts...really handy to have plug ends on batteries all the time.CheersJames
