Battery Tender Plus 12 Volt - Deltran is rated 4.8235 out of 5 by 17.
Rated 5 out of 5 by from Excellent Investment I recently bought a second Battery Tender to use on my cars I drive regularly. I bought one several years ago to use on my 1956 Chevy which I only drive about every two weeks. The last battery I had in the car lasted 12 years and I attribute that to the Battery Tender which stays hooked to the battery at all times when I'm not driving the car. I highly recommend this product. It pays for itself by prolonging the useful life of a battery thus not having to replace a battery as early as normally would be necessary.

Rated 5 out of 5 by from Very Good I've had one these Battery tenders on my fishing boat but unfortunately got damaged by the rain. They presently make a waterproof one. I am using this one on my Harley and it keeps the battery in excellent condition & ready to go. I really like the fact that it comes with two different connectors so one stays one the Harley which just plugs in when you need it and the other for any other vehicle. Eastwood ran a sale on these plus free shipping so it was an excellent value. Eastwood's service flowed like a well tuned engine...5 stars for the Eastwood Company!

Rated 5 out of 5 by from Old reliable Forgive me, Bill Jenkins, for stealing the name of your first race car, but the Battery Tender is just that. Bought my first one to keep the "little orange rocket"',my 2008 Solstice GXP well charged for a long winter's nap. Added a 4 unit model to my fleet's garage, one for the tractor, one for my son-in-law, one for my boss. Money well spent each and every time.

Rated 5 out of 5 by from Love it! My father bought this charger many years ago. I am not sure how long ago but I know it has to be at least 12 years ago. It hasn't been used lightly and it is beat up. It has some dents from being dropped but it still works great! I have charged countless batteries with this charger and it has never let me down.

Rated 5 out of 5 by from excellent investment Best thing you can buy if you store or drive a car infrequently. I store several collector cars and have drivers that may sit for a couple of weeks. With the battery tender I never worry about starting a car no matter how cold it has been or if the computers have drawn the battery down, it will start.

Rated 5 out of 5 by from This is an outstanding product I have 9 battery tenders in use, some for over 10 years. They have always kept the batteries fully charged so when I use the vehicles I do not have to worry about a dead battery. The price of these are good and you save more than the cost of it by not having to charge/buy batteries.

Rated 5 out of 5 by from Never get disapointed again You never have to worry if your bike is going to start. I mean year round. I've had the same batteries in m two bikes for 4 years now and they keep on going strong. I've used two off brand trickle chargers in the past and they both failed shortly after buying them.

Does this product work with AGM batteries? I only found lead acid battery charging in the descriptions that I have read. I don't currently have anything other than lead-acid but with AGM batteries becoming more popular, I am bound to get one sometime.

Asked by: Weber
Battery Tender lists on to use on lead acid batteries.

Can the battery be charged connected to the car, it wont damage the alternator or the car computer.

Asked by: Kikorb
Hello, Yes the battery can be charge while still hooked up to the car, It will not damage the computer or the alternator. If the car is going to be sitting for a long time with out being run, then it would be recommended the unhook the battery and keep the charger hooked to the battery to keep it fully charged.
