Charge your batteries in minutes

#21
I really like your setup FloridaBill. I have a charger for my fleet of RC Birds, it can charge nimh/nicd, pb, lipo (Lithium) Packs, the voltage and amps can be set any way you wish, fast charge, or slow. It even has a temp probe, and a PC interface adapter, to monitor voltage and charging via computer. It's a Thunder AC6 Bought it new for $43.00 I wish they made a 9V (Lipo)-Lithium Battery for my detector and pin pointer. Some of my RC Helicopters fly on a (3 Cell) (2200mah) (11.1v) (20C) with a weight of only 6.8 Oz fully charged @ 12.4V. Mega Power in a small pack. These type of packs, are a fraction of the weight for the power they can provide compared to AA/AAA/C/D/9V Ect. My pack that only weighs 6.8 oz can crank a riding mower. I hope future metal detectors use lipo packs.

I am a r/c hobbyist so i have a few of these chargers. My favorite is the Duratrax ICE. Here is an eBay link, http://shop.mobileweb.ebay.com/searchresults?cmd=SKW&kw=duratrax ice&x=19&y=10 .

It will charge any number of nicd, nimh, or lipo batteries you would need and you set the charge rate. It peaks them for long life. It will also discharge them properly so you can cycle new batteries the three times recommended before using them.

Only downside is you need a 12 volt power supply if you use it at home.
You can build your own 110 12v power supply from a pc's power supply. Just use the 12v rail and whatever connectors you want to use for charging. You can put a red LED on it to let you know it's power up. Here's the one I made but it's used for RC air.

Charging the batteries too quickly will shorten the life of the batteries. You also risk leakage and even fire.
When charging batteries they should be charged at a slow rate. Quick charging is using a higher current then the battery was designed for. That causes the batteries to heat-up and kills the batteries.

All I know is Pete & I are in our third year of charging the ex cal battery like this and it's always where I can see it because it only takes less than 10 minutes so when I get up I have my coffee and throw it on charge by the time the coffee is done so is the battery.

Sure beats forgetting to charge it for 17 hours and not being able to go that day or worse yet get to the beach and turn it on to find out it never charged because you wont know since there are no indicators, but to each their own,,,

I just bought a totally new technology.
It recharges Nickle metal hydride and Nickel metal
cadmium. It will also recoindition regular alkolyn batteries up to 9 V.

Each battery has a veiw merer that diagnoses the battery in question The readout will tell you oif it is bad or rechargeable.
and will shut it off when the maximum has been reached.

Thanks for sharing this but since I am retired and not in a big hurry anymore I think I'll just use the regular charger. Maybe have a few bourbons while I am waiting.

While this method may work for some, It didn't work for me. Why? I don't know. I bought a new battery Tender Jr, and it was showing the pack being fully-charged in minutes, but I was only getting about an hour and a half digging time before I got the low battery squeal. So I got a new battery pack and put it in the pod, only to have it do the same thing. Switched-back to the factory charger, and all seems well. For a while there, I thought my machine needed to go in for repair, but it seems to work fine. But mine may just be an isolated incident. Just sayin'. :)

All I know is I would rather charge this ex cal battery for 20 minutes, know it charged than to attempt to charge it for 17 hours wondering if and when it is charged.

Like I said Pete has been doing this for over a year with all three ex cal's he owns and has had no battery issues. If I even got a year out of them I am a happy man, batteries are cheap....

I just charged mine up in 15 minutes and felt them and they weren't even warm !!

I am not selling these, I am just offering a solution to a PIA problem with some batteries
Very nice bill thanks for the information

I charge the Excalibur overnight. In the morning , I feel the battery pack and it is always warm. The machine was purchased in June of 2012, so it is relatively new. I'm headed for Florida in December, so I will find out if disconnecting the battery since the last time it was used, has any negative effect on the Battery. I'm going to stick with the conventional overnight charging method. I have used a battery tender on my motorcycle and it shuts off when the battery is charged. I'm not keen on force feeding current into a battery but that's just me.:cool:

They will get warm, but that's usually not a problem. My Tender Jr never made it warm, but then again it wasn't charging much.
