Another dewalt 18v question

I have 2 chargers in my shop and generally kept batteries in both of them, because the instruction say that they have voltage regulators in the and won't overcharge. I read somewhere , on another forum I believe ,that a guy had one like that catch on fire and would of burned the shop down if he hadn't walked in at the right time. What do you guys do?
 
Doug WiI unplug all chrgers when I leave.

I have had to work on too many houses that had fire damage or burnt down due to Cell phone chargers catching fire.
 
Hello Doug Wi,

Remove battery after stops charging. You can leave the pack in for 8 hours after stops cha
rging, once a year, to equalize the pack. The charger has no other function. Its in the manual!

Friend of mine hooked up a four plug box on the wall just for chargers and stuff. Here is the trick, It turned on and off with the light switch for the shop lights, While he was there and the lights were on everything charged. Go home, flip off the lights. Everything safe. Maybe a bit of over kill but he was feeling safe.
 
If you look around your house is full of electrical devices. Any one of them has the potential of burning your house down if you keep them close to easily flammable things. The only thing you can do is be careful where you charge the batteries. It's about as rare as having a toaster burn up.
 
Doug,
I use dewalt charger DC9310 which is designed for all three types of batteries. Li, Ni-Mh and Ni-Cd.
My shop radio has the same charger built in.

Unlike the old Ni-Cd charger which continues to charge, the new charger will shut off completely after battery is charged.

Using the old charger to charger newer Li and Ni-Mh batteries may be a formula for a fire.

To answer your question, I leave battery in charger. When I remove the battery it's cold, unlike the old school dewalt charger. I would recommend anyone worried about battery causing a fire, get a DC9310 charger
 
And I as an insurance adjuster worked too many fires from toasters and coffee makers. One can't be too safe but I, like others, get careless.
 
Jeff, good idea on the light switch. Worked at a shop once that had the compressor contacter wired to the lights, no more forgetting to turn it off.
 
Hello Doug Wi,

My charger is plugged into a timer.

Works for me...

I charge the batteries at my employer's shop. It uses his electricity and if they catch fire they'll burn down my employer's shop.
 
My chargers are 9116 and the batteries are either 9096 or 9098. Don't keep up on the battery types so can't tell you what they are. No information on the battery itself. Thanks for the info.

The DC9116 is the old school dewalt charger that doesn't fully shut off when done charging. This charger is not recommended for Li or Ni Hm batteries, might cause fires too. You can tell when you remove battery, it's still warm 24 hrs later. That charger is only good on the old school Ni-Cds. I feel like the charger is like the old manual car chargers that will cook a battery. I would recommend up grading to the DC9310 charger so if you change to Li or cheaper Ni-MH you will have the right charger. I have two DC 9310 in each workshop and one 12v model in truck. I like the truck charger. NO TIMERS ARE REQUIRED. JUST DROP IN BATTERY AND FORGET ABOUT IT.

If your dewalt batteries are XRP they are most likely Ni-Cd. To my knowledge, dewalt doesn't sell a Ni-Mh, only aftermarket one available. If you have a dewalt Li battery, it's smaller and will say on it's Li.
