Perfect!, January 7, 2009
I have a Cadillac XLR that mostly sits in the garage. After 2 weeks of no use I got in to start and battery was dead and door locks were dead and so I was trapped in car in my garage. Cadillac road service was prompt and freed me but I didn’t want a repeat performance. The battery charger works as advertised. It took about 24 hours to charge the first time but I leave it connected and the geen light tells me the battery is fully charged. If you have a car garaged for long periods this is a must item. Modern cars, with all their gadgets, drain the battery quickly so I’m happy I made the purchase.

An essential accessory for every car owner, December 27, 2008
Most people labor under the misconception that periodically driving their car will keep their battery charged. Unless you are regularly putting up hours on the highway this isn’t the case. Average around the town driving doesn’t run the alternator enough to charge up the battery fully. This situation is exacerbated if you run the battery down for some reason (like leaving a light on or running the battery while parked with the engine off). When a battery is used for any length of time with less than 75% charge, sulfation begins to take place. Sulfation is where the sulfur in the sulfuric acid which acts as an electrolyte in the battery bonds to the plates permanently, reducing the battery’s ability to be recharged and basically killing your battery. There’s an easy solution - buy a decent battery charger and be sure to top up your battery’s charge any time you run it down - or periodically regularly for any car that doesn’t enjoy long trips where the alternator gets to charge the battery for hours at a time.

There isn’t a better charger around for the price than the Deltran SuperSmart Battery Tender plus. It’s the granddaddy - and it does the job quickly and well for a very good price. It has two indicator LEDs which show 4 status states (Verifying the battery, charging, charging with battery level over 80%, and fully charged - on trickle charge mode). This makes it easy to see what the charger is doing and when your battery is ready to roll. The Deltran SuperSmart is has a robust powder coat painted metal body and a modular plug attachment that allow you to hook up various battery connectors. It comes with two connectors (clips for car and marine batteries and rings for motorcycles).

While a battery charger cannot bring back a battery that has fully sulfated, a good one like this definitely can reverse partial sulfating. It’s better to prevent sulfating in the first place - and regular use (i.e. quarterly and after each significant battery run down event) will keep your battery in good shape for as long as possible. It’s like dental floss for your car’s electrical system.

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.
