Guest guest Posted January 3, 2011 Report Share Posted January 3, 2011 as long as it's a standalone battery and not connected to the power mains, house-current, etc should be fine. 6 volts is 6 volts in this case. So tiny a current is required that a lantern battery or a button battery would not make much difference. Just be sure it's a separate battery and nothing about it is connected to the AC 110 volts or 220 somewhere, as in a charger circuit, etc. It has to be free-standing. bG > > Hi bg, > I have a couple of questions.

Guest guest Posted January 3, 2011 Report Share Posted January 3, 2011 Thanks bg, I have a separate charger circuit that I disconnect once the battery is fully charged. I meter the voltage /amperage with a Fluke 77 (separately) in-line and across to monitor the m.a. and discharge voltage.Once again, Thank you.

Guest guest Posted January 3, 2011 Report Share Posted January 3, 2011 Freestanding when in use. You can use rechargeables, no problem, just take them out of charger circuit when you use them. That's the sensible way. In all the years, I have yet to wear out a battery doing this. The electric current available in a single AA NiMh rechargeable 1.5v battery is over 2200mAh. So if 4 of those are used together, you have 8800+ mAHours, that is 8800 hours at 1mA. We use about half of that or even less, so it comes out to maybe 20,000 hours of use before they become unusable. That is just 4 AA's. The big lantern battery could treat a whole village for a year, everyone connected to it at the same time, and still have lots of power left. It is such a crime this is not happening. bG > > > > Hi bg, > > I have a couple of questions.

Guest guest Posted January 4, 2011 Report Share Posted January 4, 2011 bg, My nephew(mid 20's), wife and two young daughters are going to Africa on a missionary calling. According to him, they will be in a remote station. I have sent him a link to your group and am searching for water filters/purifiers and economical /durable solar panels that would work in remote areas. Any information you or anyone in the group could provide would be most helpful. Supply links there are intermittent (at best). The information you and your group supply may be a pivot point for many. God bless you. Larry From: baby_grand <no_reply > Sent: Mon, January 3, 2011 8:30:04 PMSubject: Re: Battery question Freestanding when in use.

Guest guest Posted January 4, 2011 Report Share Posted January 4, 2011 hi, Larry, there is a second group: 2 where a lot of engineers hang out, suggest you post there for more help. bG > > > > > > Hi bg, > > > I have a couple of questions. I have a functioning 6 VDC. 4 A/H rechargeable > > > > > battery from an emergency light system. > > > At full charge, it reads 6.26 VDC. Do you see any problem using it for a > > > Godzilla?
