Is this safe to attach to a battery? (I know there are battery warmers, but I have this already)

I would not recommend putting it on a battery. Plus it has a magnet, so it is ment to be attached magnetically. Unless you are somewhere where it is -40, you probably don't need a battery warmer.

Yes, but melting battery lead is very dangerous and highly frowned upon. Google the off gasses of the acid. Be safe!

Absolutely. Last summer, I left my lights on and ran the battery dead. I jumped it from a car and then when I got home I put it on a Battery Tender, Jr. for a full day and let it charge up. It's been fine ever since. Were it an old school battery, I would have had problems from sulfating. These are incredible batteries, and, at least for mine, the Battery Tender worked perfectly.

Had my charger plugged in for a few days with a battery from a recently purchased yard sale 18-volt drill. The unit was warm to the touch, but not hot. I have charged other batteries and they were warm when removed. The charger changes to a solid light when the battery is charged, and I usually remove it at that time. If it's getting really warm, I'd try a different battery if possible. If same result, then I would contact vendor or B&D; as a warranty issue.

From what i have read, it is the opposite that is harmful to Lith type batteries. The combination of heat and charging while warm or hot. As to cold, it shouldnt damage them, however a side effect is that the cold reduces the charge life drastically (in extreme cold). Meaning the charge will not last as long. I have seen it many times on cold weather photoshoots with my DSLR. Have read some on the net about Lipos buldging if allowed to freeze though so i would be cautious

Yes it will stick to the battery. You can not glue it on the battery. Just try aligning it nice when you close the cover.

You could unscrew the bottom and disconnect the battery for a minute. I haven't done that with this product, but if you are handy, you should be fine unless the stupid battery is soldered directly to something. It should have a plug but I wouldn't know.

this is a connector to your battery MAINTAINER not a charger. Its recommended to be connected after the battery is charged.

Yes, it sticks to the battery. So you would need one for each battery you have.

Yes. That is what I did. I used Velcro though so I could replace batteries easily.

I have owned several and they are safe to leave unattended on my houseboat in the winter, but always plugged into a grounded wall socket. They pull too much voltage to plug into a cigarette lighter i would think. could drain your battery very quickly and maybe even short out the heater.

The plastic sleeve is meant to keep the batteries in alignment. Yes, they should work fine. If they slip out of alignment use either duct tape or scotch tape to act as the plastic sleeve battery holder.

Yes - You are correct. The battery will overheat and it can be damaged! Try using a thermostatically controlled outlet like Farm Innovators model TC3-3545 as long as the 120V receptacle (or thermostat) in the same general area as the battery.

I use the Ctek 7002 to maintain my 2 boat batteries over the winter. I bought it for maintenance and trickle charging as my batteries were not discharged very much when I connected them last fall. I can't speak to charging of a heavily discharged battery, but for my application the charger is slightly warm, but not what I would call hot. It sits on a fabric surface in my basement and has shown no issues.

I doubt it will ruin the batteries unless you store them in the cold, however cold batteries will have a lower performance. But these heat up pretty good when operating so I am not sure if it would be observable.

they're just like other lead-acid batteries and will lose their charge quicker in the cold and also sustain damage. i suggest you find a warmer indoor place for your battery. if you're using it at a ski chalet you can either hook a heater up to keep it warm when you're not there, or just transport it around with you. remember tho it's quite heavy

I'm not a battery expert, but you should really stick to the charging voltage and initial current they show on the battery. Overcurrent will certainly warm it up and it may leak or explode on you, or just shorten it's life.
