Rechargeable batts with Impact.

Anyone using rechargeable batteries that came with Pro-pack. If so, how long are they lasting when using them. And how long does it take you to recharge them? Thanks , Glen.
 
All the time!! I get 2 days full use so far but I'm not running 5k frequency most times. If I do I get more than 9 hours easy. If you buy the "PRE CHARGED" Duracells at BJ's or Costco, they are Panasonic ENELOOP batteries. Awesome life as I am a photographer also and these have the best life in flash units. I would not use anything else. I always have spares with me so I never worry about batteries. I even use rechargeable 9v batteries for my garret carrot.
 
I use Duracell Nimh (2500 Mah ) re- chargeable's I don't think they will last as long as Duracell Alkalines. I am guessing but the the Duracell Alkalines might last maybe 20% longer than re cheargeable Nimh types but I have not done no real testing to prove just how long re chargeables actually last on the impact. .. The battery bar right at the top mark stays "lit" much longer with Alkalines! The Impact needs to be run on Re Chargeables in my opinion though because it will cost quite a bit over the year if using Alkalines.. I wonder why it sucks so much juice...

This machine does NOT suck a lot of juice. I get a full 2 days all day hunting ,18 HRS, running 14k and have never gone below 2 bars. EVER! Buy good batteries to start with. READ MY POST ABOVE. If you can't find the pre-charged Duracells (re packaged ENELOOPS) Buy the Panasonic ENELOOP batteries online. These out last the cheap rechargable junk batteries.
 
I am getting no where near the hours your getting with my Duracell 2500 Mah Re - Cheargeables. I still think the Impact is generally quite a " juice sucker" than many other detectors I have used.
All I have stated is that Alkalines will give more hours use compared to Re Chargeable types. I thought Duracell Battery's were one of the best.. Not junk by my standards...

Duracell makes 3 different Nimh batteries. The Eneloop batteries say "Pre-Charged" right on them. If not, they are the standard Nimh batteries which have about half the life of the Eneloops. Another thing is to NOT use a fast charger with them. The heat build up will kill the batteries fast and just because these fast chargers say the batteries are fully charged they are not. The Eneloop batteries are a different technology Nimh that will hold full charge up to 75 days where regular Nimh batteries start dying as soon as they are taken out of the charger. Eneloops were designed for the camera industry for extreme high drain devices such as flash units. They are worth the extra dollars.

So how many hours use can you get on the impact on these super re chargeables.

I get an easy 2 full days and it goes down to 2 bars. I always change batteries when I get down to 2 bars to keep the machine at its best. I have 2 dozen batteries split 50/50 with Panasonic Eneloops and Duracell "Pre-Charged" and they run the same. These batteries are good for up to 150 charges before they degrade.
 
I use AccuLoop by AccuPower 2600 mah and they are very good. Plenty of run time and hold their charge when not in use.
 
Don't do it!!! NiZinc batteries have the been known to fry sensitive electronics!!! If you overcharge a small capacitor circuit it will fry everything. I have used them in the past (flash units) and I only got 10 charges out of them before they all died and they cost me more than the Nimh batteries with the special charger. By the way, I hunted all weekend, 15hrs and I am at 2 bars. Just buy an extra set and keep one set on charge.
 
I think an on board charging system would have been a good idea on the Impact mudwhale, I seem to be always unclipping the battery housing flap and messing about re charging...Spending too much time watching my battery monitor on the detector dipping....

An on board charging system works great with machines such as Deus where they use Lion batteries. For us "AA" guys the added weight to the unit would be a deal breaker. Almost every machine out there except XP and Minelabe and Makro's other detectors use "AA" batteries. I'm used to it and usually just change out the batteries when I get home (unless I'm Lazy and know I'll be fine the next day) and know I'm good to go the next day because I always carry spares. I keep them in rotation and like I stated before, I have more than 2 dozen from my photography use. While I always have 8 on charge, I have freshies in the Impact as well as 4 spares on me in the field. This is mostly in case of one battery failing completely. It does happen over time. It's happened to me on numerous occasions where a battery died and was a total battery failure. In this case I changed them all in the field and Diagnosed the dead one when I got home. Into the garbage. I personally don't mind changing out my batteries and it gives me a certain satisfaction that my next days hunt will be un-eventful should a battery die completely like said.

My suggestion, Buy at least 12 or more batteries. Use 4 and carry 4 and always have 4 at least on charge. When you get home, take the ones you've used in machine, put in charger, take your spares, put in machine and take the ones from the charger and use in the field as spares. Repeat this cycle religiously. I have never had an issue because no matter how much I hunt all day long, I know I am charged and good to go.

I have never had a machine fail due to battery life especially the Impact! If you hunted 15 hours straight in one day with he Impact, you would still see 2 bars remaining.
