Every time I want to fire up my old 71 Datsun (that’s Nissan for those of you younger than 30) 240 Z there’s a good chance that the battery has drained down and that I can’t start it! Looking around at car forums I read about this nifty little gadget….It’s like a battery trickle charger….sort of. Whereas it’s not recommended to keep a trickle charger hooked up all the time, this one has circuitry to limit the current and sense when the battery needs charging. It only charges at 1.25 amps which is easier on the battery.
I’ve had it on for a month now and it’s great. The first couple of days, the red light was on indicating charging. Since then it’s been on green and the car starts right up. I live in Houston where the heat and humidity can be just as brutal on batteries as the cold.
I highly recommend this “tender” for those that have cars that stay unused for long periods.
As other reviews have mentioned it comes with a set of adapters that allow you to permanently attach pigtails to the battery posts and then you can quickly connect the tender without having to use the alligator clips (also included).
For the price and free shipping you can’t go wrong!
This little gizmo is dynamite.
I have a 4 year old Accord that, due to circumstance, only has about 4400 miles. Rarely driven…and what driving is done is mostly at night.
Sat for a week once in very cold weather…dead battery.
Ordered this. Hooked it up. 100% charge and the battery is very powerful once again.( had thought I would probably need a new one).
It’s very small size makes it extremely easy to use and store. And it will not overcharge, so you do not have to babysit the process.
It’s LEDs glow red when charging. Green and red blink once 80% has been achieved. Solid green at 100%.
It did, in very cold weather, take a long time to establish a full charge on my almost completely discharged battery. The battery would have been usable in a few hours, but 100% took close to 18.
Highly recommended.
I recently purchased a Deltran Battery Tender Plus (they are made in China) battery charger for a total cost of $63.30. It has never worked correctly from the first day I got it. It charges great, but it never goes into the “storage” mode, or notifies you that the battery is at 80% charged. It apparently just keeps charging the battery whether it needs it or not.
I contacted Deltran’s “technical” department a few times about the problem, and told them that I suspected the charger was faulty, but they kept telling me it was the battery, or “check this” or “check that” or “the weather was too cold” (in Florida), even though I had told them the battery was new. So, figuring they knew what they were talking about, I purchased another brand new battery at the cost of $79.92.
I left the “new” battery on this charger for a few days, and it was the same thing as the “old” battery. The charger never showed a full charge or went into storage mode.
So now that the equipment that this battery is from has been out of service for a couple of weeks, (because Deltran recommended I remove the battery from the equipment since I was having a problem charging it), and I couldn’t afford to fiddle around any longer, I bought a competitors battery charger for $46.45, and as it turns out after connecting the new charger, within a matter of a few minutes both the “old” and the “new” batteries showed fully charged, and the new (competitors) charger went into “storage” mode with no problem.
Now that I knew for sure that this Deltran Battery Tender Plus charger was not working properly, I reviewed the Battery Tender Plus “LIMITED” 10 year warranty, and found out they (Deltran) wants a $9.95 “handling” fee (if you have had the charger over 90 days), and if you have the original sales receipt, if you want to send it in for repair.
If you don’t have the original receipt, then it is a $15.95 “handling” fee no matter how long you have had it.
Having wasted about 2- weeks fiddling with 2- different batteries and 2- different chargers all because the Deltran Battery Tender Plus did not work correctly in the first place, I am not about to spend another $15.95 “handling” fee (because I don’t have the original receipt) plus shipping (maybe $10.00) to return it to Deltran for exchange/repair, and then wait another week or two to get the charger back and have to hope that it now works correctly.
Deltran also told me that since I did not buy the Battery Tender Plus in question directly from them, I would need to send it back to where I originally purchased it. Not having the original receipt (because I bought it someplace online and don’t remember where), I asked Deltran what’s the difference where I purchased it since they (Deltran) are the manufacturer and supply the warranty as well, and I was told that “it is the same as trying to return a Chevrolet to a Ford dealership”. That I don’t understand, because if a person has a problem with a Chevrolet, they can take it to any Chevy dealer in the country and have it fixed (and maybe any GM dealer).
They also said in so many words that I should have known sooner that the charger was defective, which must mean that their “technical” department is not fully competent to be advising anyone, and that I should have not paid any attention to their suggested remedies in the first place.
Because of the investment of time and money I now have in this Battery Tender Plus, and the poor “technical” support I received from Deltran, I would never buy another one and would not recommend it to anyone else. Their 10 year “LIMITED” warranty is also a joke. Battery Tender PlusSucks! It should be called Battery Tender Negative!.
