Battery Tender Plus 12V 1.25 AMP Car & Motorcycle Battery Charger and Maintainer, Float Charge for Automotive, and ATVs - Smarter Than a Trickle Charger

A 2003 BMW and a Michigan winter is already a bad combination on paper — old electronics, old battery habits, temperatures that seem personally offended by the concept of a car starting. Add in weeks where the car just sits because who's driving anywhere in a polar vortex, and you've got a recipe for a dead battery and a bad morning.This thing quietly fixed all of that. Hooked it up, left it plugged in through the worst of it, and the car started every single time like it had no idea what season it was. No clicking, no jump-starting in a parking lot at 7am, no calling anyone for a favor.The "m

I PURCHASED MUTIPLE UNITS. THEY FUNCTION PERFECTLY KEEPING THE BATTERIES UP ON MY CLASSIC CARS.THEY OPERATE NEARLY SILENT. EASY TO USE & THEY WONT OVER CHARGE YOUR BATTERY. EASY TO USE , EASY TO CONNECT.I HIGHLY RECOMMEND THIS PRODUCT!!!

UPDATE -- It's now been 3+ years since I purchased this battery tender, and I couldn't be happier with it. I've continued forgetting to start up my vehicle, so I've continued needing to charge its battery. Much to my surprise--and delight--I found that the Deltran Battery Tender *WILL* indeed charge a completely dead battery! Yep, I know it will, because I've now done it several times! In each instance I simply hooked it up and left it for about 12 hours. I have no idea how much of that time it actually needed, but by the 12 hour mark my battery was charged. This is in a Toyota RAV4. I LOVE th

Highly recommend the Battery Tender Plus 12V charger and maintainer. I currently have two of them and will probably end up buying a third—they’ve been that reliable.They do a great job of keeping batteries charged and maintaining battery health, especially for vehicles or equipment that sit for periods of time. It’s really helped extend the life of my batteries and saved me money in the long run.They’re simple to use, dependable, and just work exactly as they should. If you’re looking for a solid battery maintainer, this is a great choice.

I was impressed with the packaging, the easy-to-understand instructions, the quality and simplicity, but then I thought it wasn't working properly and feared it would over-charge my new battery (due to some 1☆ reviews I read).My situation: we have a spare vehicle we only use once a month and then only drive short distances. After killing a 2 yr old battery, we got a new battery and our mechanic suggested a battery tender for this vehicle so I bought this. We had a new battery in the car. I hooked this up to the battery and it showed a red light for over 5 hours (meaning it's in charging mode).

Purchased this battery charger for my H/D and worked perfect. I now use it for my Duramax diesel truck periodically to keep the battery at full charge after too many short trips. Moved to Texas and with the heat and winter cold I use it at least 2 times monthly to top off my batteries and keeping them charged to proper voltage. This charger has been through a lot moving but always worked. Very sturdy metal case. 4 stars because it is getting old in design but so am I. 15 yrs old still working!

Battery tender is the perfect size for my motorcycle. It can be set up for direct connection to the battery for fast charging without taking the battery out.

I purchased this battery charger due to the many positive reviews and comments and I am NOT disappointed! I have struggled with my car since I purchased it because every spring after I take it out of storage the battery has died. I have needed to buy a new battery each spring because the battery was ruined. Being a vehicle that isn't driven often, and stored in the winter months, I decided that I needed a battery charter and maintainer to keep the battery charged when not in use for long periods of time. It is crazy how fast the battery will drain from sitting for a week or longer. This charge
