in the replacement of new batteries on my 7865XL norelco, is there a wrong way way to install? I notice they are not marked positive or negative batt

The ends of the batteries with the single metal strip show be the postive. Just make sure that end is pointed towards the head of the razor.Charge the razor and it's like new.

Yes, you need to use a volt meter to find the positive and negative side of the battery.

I'm in North America. Make sure that the positive side of the batteries are put into the position in the charger where the positive polarities are. Make sure that the negative sides are where the negative side of the charger is. There should be a latch on the negative side pushing them forward to charge. I put these batteries into a high power LED flashlight. They are outstandingly powerful. Good luck.

On the white plastic carrier that holds the batteries, on the side on it, there is a faint outline of an arrow. This arrow needs to point inward as u put it back in the light. As far as positive and negative, any device u put batteries in....u put the flat part of the battery on the spring

Eleanor, normally you would place the batteries in with the negative side first. BUT, that is if they are going in one on top of the other.

You should be able to wire together all positive an all negative and just connect one + and one - to the battery. The current draw is fairly low so it should be no problem.

I have only been able to insert the batteries one way. The plastic shapes on the inside are designed so that the bulge on the positive side of the battery fits just overtop of a mold, while the smooth side is tight against the edge of the container. If this is reversed, the positive side does not fit in, and the flat side juts over the mold so that the cover cannot close.I would personally recommend keeping only your charged batteries in the case, and using a rubber band or something to bundle your discharged ones until they are replenished. Or you could buy more cases and label them. That would look much better actually. I have only been able to insert the batteries one way.

Mine came brand new with a dead battery. You need to desolder the old battery and solder in replacement, or just splice in a CR 2032 battery to make it work. Wrench

Turn the lantern upside down. Unscrew the black cover, If the old batteries are still correctly installed, replace them one at a time with the same orientation, replace the cover with the tab in the slot, and screw it down. If the batteries have been removed, take out the inner cage and insert the new batteries in it one at a time with the plus sign as marked. Replace the cage with the batteries sticking out - it only fits one way. Insert the tab on the black cap into the slot, press it down and screw it on.

Hi Diane H. - Remove the 3 screws - latches located at TAX- CI/C & 1 0 on left side .TAX switch M- & - = on right side . Lift top up LCD part , a little , Twist the two halve in opposite first latch , Push to side get the other , separate halves . Battery AG13 / LR44 what ever . Look at battery , in center is a little tab pushing on top of Battery , when done make sure it's there Push battery out LCD side , not over the circuit board , may need to bend tab on side of battery holder , replace battery note + & - are right , Also note little tab on top of battery holder bend side tab back to , after installing Battery - reassemble. I hope this helps

pull off the solver cover...then the battery will be able to taken out and replace or what ever you need to do. obviously observe the polarity of the positive & negative when you replace cover.

Whoops. Thought you were asking how to "charge". According to your manual: Replacing the Battery Uses one 3.0 volt "CR2" lithium battery (Tri-Tronics #1181300). Remove the collar strap from the Bark Limiter. Unscrew the 2 screws on the bottom of the Bark Limiter, alternating between screws, until the two halves can be separated. Remove the old battery and install a new battery, matching polarity.

I don't remember for sure. I'm thinking it was the black. You can easily find out though. Just hold one wire on the battery positive and ground the other. If it lights up you know which is the positive. If it doesn't light up just switch the wires and it should work.

Several possibilities for the problem. Use quality batteries such as Duricell and be sure to buy from a supplier with a high turn-over. Be very sure that the battery's are fresh. Even a dead battery will measure 1.5 volts but it will not be able to deliver the required current. When operating with low voltage, contact resistance is always a problem. To minimize this resistance issue, always spin the battery's after installation, this polishes the contacts. There is always the possibility that the unit is defective. I have not had any problems with my unit..............hope this helps.............Bill Several possibilities for the problem.

Hello Brian, The instruction should be on the back of the black box. Please remove the plastics on the battery terminal before using the battery. Thank you

Slide the top in first to match the connectors, large connector (negative) on the left. Then push the bottom part in to the battery compartment. Good luck.

Almost all, if not all button batteries are stamped with their brand name, type I.D. and a positive symbol on only one face of the button battery cell. Since the opposite, rear, or unmarked face of the battery is always the opposite polarity to the marked polarity, and considering the marked polarity is always positive (+), the opposite face will be negative and thus no negative (-) mark or stamp is required. With button batteries their proper installation into a product, e.g. a watch or calculator, is normally assured by their physical stepped edge design which dictates in what orientation they must be installed, i.e. which face should face into the device. Normally this would be the unmarked face. The marked face you will normally see after the battery is locked into place. If the battery's power is exhausted and it is properly installed, then the device it is to power won't work. Normally putting in a fresh battery in its correct orientation will get the device working again. If that doesn't fix the device, the device is either defunct or you may have installed yet another exhausted or dead battery. A voltmeter is really the only practical testing tool that can tell you if a button battery is exhausted, that is to say dead.

You merely remove both small screws, take off the cover, take out the old batteries and insert the new. Watch what direction the writing on the old batteries face so you insert the new ones properly.
