Battery Life Saver - anyone used this?

$114 buys you 1 battery and that is warrantied to solve the problem. With the ability to cost you a tow and an alternator I wouldn't recommend it. There are places that sell 'reconditioned' batteries - but, even when bankrupt I am not that cheap.
 
Do a Google search on sulfated batteries. Once they're dead, they're gone. No charger will bring them back.
 
No they aren't, CTEK's have a specific Mode for bringing back Sulfated Batteries.

You Charge the Batteries on Normal or AGM / Cold Weather Mode...when that's done, you Switch to Recondition Mode.

When everything is done, the Charger will Analyze the Battery and let you know if it is Operable or Shot.

Unless you've actually used a CTEK, you can't really Comment on what they can / can't do, they are a VERY Capable Charger.
 
Yes. Get the 7002.

I was gonna Sell mine and get the 25000, but the 25000 Model doesn't have Cold Weather or AGM Modes...whereas the 7002 does.
 
I have charged the batteries on trickle charge for several days, cycling them. Once the charger is off, the voltage drops slowly to hold at about 10.5 volts. It will hold at 10.5 volts for days. I had a fluorescent light hooked to one for about 6-7 hours and there was almost no drop at all (went from 10.49 to 10.48, I think. Based on this limited information, to those that have used this CTEK charger, do you think these batteries might be a good candidate for resurrection?

It looks like this 7002 model is about $110 on Amazon, so, obviously, I'm still wondering if it will be worth the money.

Also, to those that have used these, what is your experience with them in terms of battery longevity? If I would have used this on my 8-10 year old Interstate Megatrons, would I still be using them today, in your opinion?
 
How old are the batteries that you are using? If they are not to old, then it may be worth a shot. If they are old enough for replacement, then it is a crap shoot. If it is not holding the voltage, then it may be time to replace.
 
We used the CTEK's in our shops and had pretty good success. If the battery had internal damage or had so much buildup in the bottom that it shorted the plates the battery was history but other than that it usually came back. I was at Walmart a few years ago looking at the marked down stuff on an end cap in the automotive section and there was a Black & Decker charger/reconditioner in a greasy, torn up box (obviously a return) for $9.00 so I figured I'd give it a try. Took it home and stuck it on one of the batteries for my electric trolling motor that was getting weak, grabbed the cooler, and went fishing so I could test it. Worked great and the battery is still working fine. I had about 6 batteries on a pallet that had sat for a couple of years so ran each of those. Two came back. then I tried the old trick on the last 4 of hooking the batteries in parallel (pos. to pos. and neg. to neg.) with jumper cables and hooking the charger to the good battery (in the charge mode, not the recondition mode) and brought back two more, which I then ran through the recondition mode. The two that wouldn't come back had bulged cases and I'm sure had frozen at some point. Probably came out of parts trucks I'd drug in. The only problem I've had is the cost of beer since running the battery on the trolling motor is the best way I've found to give the battery a good test.

Normal voltage is 12.6v from 6 cells. This is about 2.1v per cell.

So 10.5v is 5 of the 6 cells developing full voltage and one cell shorted out. As mentioned above they can't recover shorted cell situations.

You should look for a local place that sells reconditioned batteries.
 
In thinking about this further, I may end up with one of these anyhow, just to use for my truck batteries (my good '95), since I don't drive it the salt. It's known to sit for months on end and this might be a good piece to keep some life in them for a longer period of time.

Anyone who has boats or RVs knows that non-use is death for batteries. Need to keep them charged. If they're left sitting in a discharged state, there's no bringing them back. The siltuation is permanent and no charger will reverse that. Trickle chargers are great for preventing this. I have 3 boats and plenty of infrequent battery use. Every boat has an onboard battery charger that stays plugged in.

If you're considering the charger as means of preventing the batteries from dying while not being used for months at a time, by all means do it. If you think a charger will recover a sulfated battery, your playing with yourself.
