+KrazyKrew Posted October 11, 2004 Share Posted October 11, 2004 I never took the time to buy rechargeables. But I figured I would need to with my GPS as I would be spending a lot of money on Batteries. Well I bought Energizer e2 Lithium and a charger by same brand. Well the 1st Energizers I bought the regular kind last many trips out and many times playing and learning the unit and are still about 1/2 strong. But I charged my rechargeables for 2 days and put them in and in one day out only about maybe 3 hours of battery use I got the low battery signal and unit started to die. Are all rechargeables this quick to die. If not what is a good brand for AA that lasts and holds a strong charge. the battery package says LONGEST LASTING AA BATTERY IN HIGH TECH DEVICE. Thought I made a good purchase. Not impressed. After 35.00 for charger and batteries I am depressed! Krazy Krew Quote Link to comment
+Renegade Knight Posted October 11, 2004 Share Posted October 11, 2004 The Everedy Lithium batteries that I see in the store are not rechargable. The ones that I do see are Nickel Metal Hydride (NiMH). Double check your package. If you do have Lithium rechargables awesome! But then check your recharger to be sure it's for the Lithum as if you got a NiMH recharger it may not work so well. I'm not sure if lithum takes a higher voltage or what, but most NiMH chargers only claim to do NiMH and NiCAD batteries. Quote Link to comment
+KrazyKrew Posted October 11, 2004 Author Share Posted October 11, 2004 ok I did it. I paid 10.00 for these batteries and I put in charger for 2 days and ran them down on my own and they ARE NOT recharable batteries. My mistake 100%. I should take the time to read package. Quote Link to comment
+Renegade Knight Posted October 11, 2004 Share Posted October 11, 2004 Lithum batteries are great cold weather batteries. They charge a pretty penny for the things. Everedy also makes the Rechargable ones. The last time I looked they had 2300 milli amp hours ones out. The higher the rating the longer they last in your GPS. Good luck. Quote Link to comment
+pcmike Posted October 11, 2004 Share Posted October 11, 2004 The e2 lithiums are not rechargeable like you said, but I've had the best experience with them. I'm a weekend (4-10) and random (random cache every 5-10 days) cacher and the e2s last me a good solid month. This was before I got my automotive mount w/ cig adapter, so I now expect these batteries to last me even longer. I love them, they're light... last along time and hold a more constant charge (like it matters on a GPS, but still). I'll continue to pay the $10 for 4 of these batteries, they perform too well to switch! Quote Link to comment
+Byron & Anne Posted October 11, 2004 Share Posted October 11, 2004 (edited) Before spending the money on rechargable batteries check your owners manual for the piece of equipment you're going to use them with. Different type of batteries have different voltage outputs. NiMH batteries are about 1.2 volts per battery. Alkaline are about 1.5 volts per battery. (AA and AAA) If you put NiMH batteries in a piece of equipment that wasn't designed for the lower voltage if might not work, or you get an apparent short battery life.

+5nomads Posted October 11, 2004 Share Posted October 11, 2004 If you would still like to have rechargeables, I recommend Maha 2300. They are very long lasting, and charge at a low temp when used with Maha's pulse charger. I use them in everything. Quote Link to comment
+Learned Gerbil Posted October 11, 2004 Share Posted October 11, 2004 I agree - I was growing disillusioned by rechargables until I discovered the 2300s - they seem to last forever! Quote Link to comment
+jollybgood Posted October 11, 2004 Share Posted October 11, 2004 I agree. The brand can make all the difference in the world. I use PowerX batteries exclusively because of the excellent guarantee/replacment program along with the MAHA charger. I still have my first pair of PowerX batteries (about 3 years old) and they still hold a decent charge. Quote Link to comment

CharlzO Posted October 12, 2004 Share Posted October 12, 2004 actually, the camera manuf. recommends NiMH because the power drop slope is a lot more gradual than an Alkaline. An Alk has more volatge for decent period of time, but when they start to drop, they go quick. The NiMH doesn't have the same max power, but it stays at a more level reading longer, and takes longer to drop down. just to put it out there lol. I personally use (when I use em) the new IC3 batteries (they charge in 15 mins) and are I think a 2100 or so rating. Quote Link to comment
+NightPilot Posted October 12, 2004 Share Posted October 12, 2004 Alkalines work well in low current draw applications, but don't do very will in high current draw applications. Camera flashes are high current devices, and will kill alkalines very quickly. Alkalines work well in a GPS, but the NiMH rechargeables are cheaper in the long run. Quote Link to comment
+YuccaPatrol Posted October 12, 2004 Share Posted October 12, 2004 (edited) There is not a handheld GPS out there that will not go a whole day on a set of rechageables. Toss an extra set of batteries in your caching bag and you won't ever have to worry about losing power. One thing I have done in the past few years is to do my best to buy small electronics that use AA batteries only. With about 20-30 rechargables around my home, I always have plenty of power and if I am on the trail and need extra batteries, I can scavenge them from a device not being used at the time. Alkaline batteries are best left in a flashlight that rarely gets used and needs to work if I try to use it 3 years from now. . . . Edited October 12, 2004 by YuccaPatrol Quote Link to comment

trashcann Posted October 12, 2004 Share Posted October 12, 2004 My magellan Meridian gets 16 hours of use out of a set of 2300 mAH Energizer batteries. In cold weather this might be reduced but when I go out I have little worries about my batteries going dead Quote Link to comment
coureur des bois Posted October 12, 2004 Share Posted October 12, 2004 In my Garmin 60CS, I always use NiMH batteries. My GPS unit usually pulse a bip after 4 hours on continual use. Then I replace the batteries. I am satisfied with that. I put my unit under my coat and use an external antenna, most of the time, for the gain of accuracy. Jacques Quote Link to comment
+pcmike Posted October 13, 2004 Share Posted October 13, 2004 You need to try some better batteries! 4hrs (even with continuous use) is unacceptable. I've gotten and I'm sure plenty others have too... way better performance! Quote Link to comment
+NightPilot Posted October 13, 2004 Share Posted October 13, 2004 Lithiums do last longer unused, but alkalines will last for a few years, while NiMH batteries will self-discharge after a few weeks. The premium you pay for lithiums over alkalines may be worth it, but I'm not completely convinced, unless you really plan to leave that flashlight unattended for several years. Quote Link to comment

Sounds about right for the indicator to go from 4 full bars down to 3 bars in only 4 hours of continuous use. Quote Link to comment
+CompuCash Posted October 13, 2004 Share Posted October 13, 2004 both my Magellan and my Garmin have settinging in the unit for the type of battery you are using - make sure if you are set for NMHi batteries if you are using them. Quote Link to comment
+5nomads Posted October 14, 2004 Share Posted October 14, 2004 NightPilot Posted on Oct 13 2004, 03:32 AM Yep, and if that is your intended use, be sure to reverse one of the batteries in the chamber to prevent slow drain and your will have light when you need it. Quote Link to comment
+NightPilot Posted October 15, 2004 Share Posted October 15, 2004 If you want to have something lying around ignored for years, and then have reliable light when you need it, you might want to look into one of the 'shake' lights. They don't use batteries at all, they just use movement to generate power; you shake it for 30 seconds or so and get a few minutes of light. You can get one for about the price of a couple of sets of lithiums. Quote Link to comment

+NuvoSeeker Posted October 16, 2004 Share Posted October 16, 2004 In simple terms, please, (for a non-technical person): What are the differences a person should consider among rechargable Alkaline, NiMH, NiCad or Lithium batteries for use in an Etrex Vista GPSr? Thanks! Milt Quote Link to comment
+Night Stalker Posted October 17, 2004 Share Posted October 17, 2004 I am using a Garmin 60CS with NIMH 2100's. I am also using the MAHA charger. This charger completely discharges the batteries before recharging them. This maximizes that charge in the batteries. This combination gives my GPS a life that exceeds 20 hours. I keep WAAS off and turn the compass off until I really need it. I don't know how much this extends the battery life, but I am sure it is significant. I have long since paid for the charger with the savings in batteries. Quote Link to comment

coureur des bois Posted October 17, 2004 Share Posted October 17, 2004 Sorry for the bad link. I tried to put an illustration here, but did not have success. What I wanted to show is a combinaton of 8 batteries giving 10-12 volts for the GPS unit and the Palm. This lasts an all day long for GPS, Palm and external antenna.

peter Posted October 17, 2004 Share Posted October 17, 2004 What are the differences a person should consider among rechargable Alkaline, NiMH, NiCad or Lithium batteries for use in an Etrex Vista GPSr? Rechargeable alkalines can be significantly cheaper to use than regular alkaline cells, but suffer from relatively few recharge cycles compared to other rechargeables. If allowed to discharge fully then they won't hold as much of a charge on subsequent cycles. Usually they only hold a reasonable charge for about 20 - 50 cycles. NiCd cells can be recharged up to 1000 times, but have a limited capacity (under 1000 mA-hrs) and have almost completely been replaced in the market by NiMH cells. NiCd cells self-discharge faster than alkaline, but not as fast as NiMH. NiMH are the most commonly used rechargeables for GPS receivers. They can be recharged hundreds of times and provide high capacities (up to 2400 mA-hrs) so the run time per charge is at least equal to what you can get from good single-use alkaline cells. One drawback is that they self-discharge fairly fast so they'll lose about 30% of their capacity after just sitting for a month (the rate is also highly dependent on the storage temperature). It's recommended that you charge them shortly before use to get the maximum performance. Rechargeable Lithium ion cells have a chemistry that provides a much higher voltage (over 3V as compared to 1.5 V for alkaline and 1.2 V for NiCd and NiMH). Therefore they can't be directly substituted for other AA cells. One work-around is to make them in a shape that resembles a pair of side-by-side AA cells and this is the RCR-V3 type of Li+ cell. [Two 1.5V AA cells = One 3V RCR-3V] These look very promising with high capacity, low self-discharge rate, and good low-temperature performance. But they don't work in all devices that take AA cells depending on the exact shape of the battery compartment and they require a special type of charger. I haven't tried these yet in my GPS receiver and don't know for sure if they fit properly in the eTrex series. [Note that the Eveready Lithium AA cells have a completely different chemistry that gives about 1.6V and is *not* rechargeable.] Quote Link to comment
+4x4 Trail Busters Posted October 17, 2004 Share Posted October 17, 2004 If anyone is interested, I was visiting the local Wally Mart the other day, and while waiting for my wife to finish shopping I strooled over to the sports section and lo and behold they have in their display case a battery charger with four NiMH batteries made by Garmin. Now the salesman wasn't around so I could see them but, (Garmin) there in the market to compete with the rest. Despite what their literature says about using rechargable batteries.

+Fitzdawg Posted October 17, 2004 Share Posted October 17, 2004 I recently purchased some 2200 mAH NiMH rechargeables from Wal-Mart (basically generics) and a charger for considerably less than their brand name counterparts. The package came with both a AC plug and a Cig. adapter plug. So far I have no complaints about the performance in my etrex legend compared to regular alkalines. Besides, for the money I save in the long run, I'm content to get slightly shorter run times out of the rechargeables (a spare set in a backpack only weighs a few ounces anyway).

+tneigel Posted October 18, 2004 Share Posted October 18, 2004 My sportrax eats up the recharables. I get little time compared to you guys. Like 2-3 hours. The true test will be when I use the same ones with the same charger in my new 60cs. I hope they last longer. Will see. Also, a lot of batteries rate their rate as 1800, 2000,2300. However under use and a few uses, they don't hold onto that rate. Of course you can get the 2300's or the highest and if they don't hold it, you hope they do better then the competition. However some cheap batteries like radio shack won't hold their rating long. I use some (since I had to buy some on vacation in a pinch). I do by the new energizers, however don't buy the ones included with the charger combo because the include the lower rated batteries (even the 1800's) so look over the packaging carefully. I did get some industrial unlabeled sonys (all green) and they were something like 2000, but that still outperform the 2300 energizers. They all seem to work ok in my dig camera so I am not sure why I get the low run time. And I do the deplete option often on the charger too. Most chargers have that fold out ac plug which has been problematical at best. I mean junk... Still like the quickest charge since I use the converter in the car to charge them on trips (a moose gift). stuff tom Quote Link to comment
