Voltage output for xs battery

[smoldrn]

Does anybody know what the voltage should be on the rechargeable battery for the xs? Mine's not holding a charge very long, so I took it to Batteries Plus to see about them rebuilding it. The tech called me & said that the battery case says 12 volts, but in order for it to do that, there would have to be 10 batteries in the pod, vs 8. He said that 8 batteries would only give you 9 volts.
I put in a call to ML, but they can be slow about getting back to you. Are the rechargeable pods available for sale anywhere?

[size=large]don't have the voltage output facts but just in case ya don't have an owners manual mine says the 1600 rechargables are good for up to 16 hrs. at a time. the reg. aa alkalines are rated for the same time. there has to be a plus and minus in that somewhere. the 1800 NiMH pack is rated for 20 hrs. if you don't have Andy Sabisch's book, " The Explorer/ E-trac Handbook", he puts the life use at 12 hrs. for the battery packs. he does say to pick up some 2000+mAh NiMH batteries along with a fast charger. page 174 in his book. unless you want to keep buying alkaline batteries or a ml spare pack at outragous price.don't know what you think the life of your batteries should be but thats the facts so far.

8 when charged can reach 12V

Apparently each is 1.5 V because the manual indicates its a 12 V pack. However, on page 73 of your owners manual will will see the 1600 NiMH reaches about 11.2 V. That means about As far as how many hours you get depends on your using head phones, how long it was charged, and your settings and hunting conditions. The more it beeps the more juice you use. Even weather conditions can affect a battery. The charger is more than adequate at 15 VDC. The detector has a power regulator so you should not see a significant depth loss as the batteries are depleted.

Just found an old spec sheet on this machine where it says the battery pack is only 9.6 volts.

Alkaline batteries when fresh are 1.5 volt. NiMH are 1.2 volts. So you get 12 volts for 8 alkaline, 9.6 volts for 8 NiMH. Alkaline batteries tend to drop their voltage steadily as they discharge, while NiMH tend to stay near the 1.2 volts and then drop quickly when they run out of juice. Most electronic devices have an internal voltage regulator that limits the voltage to the circuitry, so even if you pumped in more volts it would not matter, as some have suggested trying in these forums over the years.

Best thing to do is get another spare alkaline pack, or use the one that came with the detector and fill it with NiMHs. I've tried several kinds over the years and right now am using eneloops. They are low self discharge batteries, which means they hold a charge much longer than standard rechargeable, but typically have a lesser Amp hour rating. Makes a big difference if you don't detect and/or recharge often. You could tear apart the factory rechargeable pack and replace the batteries, mine is also to the point were it won't hold much of a charge. But it is glued together and might be hard to reassemble. I think I picked up a couple of spare alkaline holders a few years back for not much. NiMH batteries are a couple bucks apiece. I have both a MAHA charger that will charge the whole pack, and a Lacrosse charger that you have to charge each battery individually.
