    this battery pack is from a Metz Mecablitz 216 L27CR I have tried contacting the battery manufacturer (Creasefield Ltd) and Metz without any luck. I was hoping for a suggested alternative supply source.

SOURCE: Need help diagnosing dead UPS

Very likely, "would this also explain why none of the indicator leds are working?"...the dead batteries are your problem. you can try this test, since you had it opened: 1.) disconnect internal batteries, label the wires by terminal location. 2.) connect (2) 12 volt car batteries to same exact wires that you just disconnected, noting correct polarity. 3.) power up UPS. if everything ok, then buy 2 replacement batteries for UPS. if not ok, buy new UPS after through search inside UPS reveals no blown fuses or other faults including poor wire connections.

Wsi-op200 won't hold charge

The short answer is: buy a new one. The long answer is: the battery can be replaced with a ATC Cordless Phone Battery 3.6V NiMH for Sanik 3SNAAA55HSJ1 3SNAAA60HSJ1 series (amazon, $3.16)(this battery is the correct size and volt, but has a higher milliamp rating) This, actually, is a battery for a cordless phone. The old battery is not meant to be replaced, but this one will work. To do this: 1) remove the base from the unit, 4 screws can be removed with a long narrow Philips head screw driver. you can insinuate the driver into the corkscrew area. 2) pry off the black switch, this can be done with a small flat screwdriver. 3) slide off the silver sleeve from the unit. 4) separate the black plastic clamshell pieces by removing four screws. 5) remove tape form battery and cut wires next to battery. 6) use a dremmel grinder to create more space at inner side of plastic base part(battery will not allow unit to close as it is flat and OEM battery is curved) 7) solder battery leads to unit leads(electrical tape to cover solders). 8) screw unit together. 9) put axle for switch back into place and slide silver sleeve back over unit.(may need some lubricant and coaxing) 10) screw base back to unit(may need to carefully tape screws to driver so you can get them into place 11) recharge(1-2 hours of work).......or BUY A NEW UNIT.

How to Open a Laptop Battery & Replace the Lithium Ion

Laptop batteries, like all rechargeable battery packs, lose their charging capacity over time. Because new Laptop batteries are expensive, replacing the individual cells inside the battery casing can save a lot of money. However, rebuilding a battery sometimes does not work as expected, so it’s important to be willing to purchase a new laptop battery if the procedure fails.
HP Pavilion DV1100 Battery 12 cells
1、Allow the laptop battery to run down completely. Turn off your laptop, then remove the battery. Write down the model number located on your battery to help identify the type of Li-ion replacement cells you need to purchase.
2、Split open a small section of the laptop battery pack (at the seam) with a screwdriver or craft knife. Continue to pry the plastic case loose moving around the outer edge until the entire top is free. This may take a bit of force.
3、Note the number of cells inside the case (usually four to eight). Write down the part number and voltage information printed on the cell casings. Draw a diagram showing the arrangement of the cells and how they are connected, or take a few photos to help with reassembly.
4、Purchase the correct number and type replacement batteries from online shop such as, based on your battery model and cell specifications. Six Li-ion cells typically cost around $30 to $40.
5、Carefully remove each cell using a craft knife and wire cutters as necessary. Each battery pack is different, but the cells are usually wrapped in a plastic casing with metal contacts attached to one end. Lay the metal contacts, wires and casing material aside.
6、Use double-sided tape or a solder gun (only if necessary) to attach the metal contacts to the cells and circuit board. When finished, the old cells should be completely stripped (naked) and the new cells should look like the old ones as much as possible.
7、Place the new cells inside the case, referring to your diagram or photos if necessary. Glue the battery(Compaq DV6000 Battery) pack top back on. Charge the new battery for at least 24 hours before using it.
Tips & Warnings
Keep an eye on the new battery while it charges for the first time. If the contacts are not connected properly, the battery could overheat and cause damage to the laptop.

How to replace a battery in a waring pro wine opener

Replacing requires some soldering skills.
1. Remove two screws in bottom end and pull off the bottom sheath.
2. Remove six rubber plugs that camouflage six screws.
3. Remove the six screws. The opener will come apart in halves and the motor assembly may drop free but will still be connected so be a little careful. Take note of the orientation of the larger spring near the bottom and the positions of fittings that mate with the shell.
4. Unsolder two leads connected to the old battery pack and remove it.
5. Now you have options for replacing the battery pack. The pack consists of four Nickel Metal Hydride batteries connected in series.
a. Buy replacements (I didn't do this so I don't know if a pack is available that is already assembled). You might have to buy four same-size batteries and assemble the pack yourself. You can determine size by cutting the shrink wrap away from the battery pack to expose the actual batteries.
b. Buy standard AA (or AAA) cells, rechargeable (Nickel Metal Hydride) cells that are readily available everywhere.
6. (Unnecessary if you found a pre-assembled pack). Assemble a battery pack by soldering battery terminal to battery terminal such that all four batteries are in series. You can arrange adjacent batteries with a plus terminal and a minus terminal next to each other. You can make the four batteries into a pack by winding them with electrical tape.
7. (Unnecessary if you chose step 5A). Using a sharp knife or a Dremel tool, whittle away most of three ribs that are formed into the plastic shell. There are two ribs to do in one of the shell halves and one(+) rib in the other shell half. The (+) rib is near the connector block mounted under the operating switch and you can decide how much of it to whittle away also. The objective is to get the new battery pack to fit in the shell halves when they are re-assembled.
8. Solder the plus(red) wire and the minus(black) wire to the new battery pack -- those are the two wires removed in step 4.
9. Add padding if you desire to keep the battery pack from rattling around inside the shells.
10. Reassemble the shells and the bottom sheath.
11. Enjoy your wine.

My 18 volt worx battery will not hold a charge

A lot of ni-cad packs have one or two bad cells. to find the bad one(s); unscrew the cover on the battery pack and use a voltmeter set on dc volt 2v full scale and test the cells one at a time. they should each have at least 1.25 volts. The bad cells can be removed and replaced with good cells from other discarded packs. If they're not too old many ni-cad cells will still work. You can also revive some cells by unplugging the vent hole in the top of the cell so it can breathe (seriously). Also, I have zapped single cells by momentarily connecting them one by one (even in the pack) to a car battery. plus to plus,minus to minus. But only for about a half second. Also, heating ni-cads will kill them.

Milwaukee tool 18 volt nimh battery won!t charge

If the battery pack is more than 2 years old its time for a replacement. The typical charge/discharge life cycle of a rechargeable cell is 500 - 700 times and the shelf life is about 3-4 years from the date of manufacture. If the charging indicator lights up when you dock the battery on to the base and still does not work after 5 hours - its due for a replacement.

The battery won't hold a charge, is there a fix or is it replaceable?

Hi there,

Well first of all you may check that the charger (adapter) is working or not, you may use a volt meter to check it out or use another charger to make sure....... further you may follow the step below -
1. Remove the battery pack from Vacuum.
2. Hold down the power button for five seconds.
3. Reinstall the battery to reset the system.
4. Plug the Charger directly into vacuum.
5. Charge the battery untill the power light is solid green again and keep the vacuum on the charger for an additional 72 hours (3 days). Important: Do NOT interrupt this charging cycle.
If further you have the same problem it means it's time to change the old battery with new one.

Good Luck!!

Thanks for using FixYa!!

Need to change the batteries in a Stanley bar flex light. lost instructions. how do you change the batteries.

I know this thread is old, but I just had to change the battery pack in mine. I could not locate a 4 pin battery pack so here's what I did:

You'll need: 3 NiMH 1.2v AA solder tab batteries, Razor blade, #1 Phillips driver, Kapton tap (standard electrical tape will do), soldering gun/iron, spare 18awg wire
1. Use a razor blade to remove the black sticker from the bottom of the flashlight base, it covers the magnets
2. remove the three outer phillips screws (the inner ones hold the magnets in and can stay installed)
3. Pull off the bottom plate
4. Pull out the battery pack and disconnect it from the flashlight at the 4-pin queeze connector
5. Remove the outer wrap and end protectors from the old pack keeping the end protectors in tact
6. Assemble the 3 new batteries in the same configuration as the old pack using Kapton tape, connecting + to - at the same two spots (use the old pack as a reference)
7. Carefully desolder the 2 wire leads from the old battery pack
8. connect up the 2 power wires to the same two spots as the old pack and insert the temperature probe between two of the batteries as in the old pack
9. Put the end caps on the new pack and wrap the entire thing in Kapton tape to simulate the plastic wrapper you removed
10. Install pack in to base, secure bottom plate and re-adhere black sticker(if needed you can use non-foam double-sided tape or spray adhesive)

The old pack was rated at 1300mAh and I used three 2000mAh each for a total of 6000mAh so theoretically the light should run for about 6 times as long between charges.

Versapak battery will not hold charge

If it is an old battery (3 plus years) it probably needs to be replaced. The other failure point is the charger. That can be checked with a volt meter. should be about 4 volts for each battery in the system. 1 battery 4 v, 2 batteries 8 v. Depending on the system it maybe either ac or dc. Try both with your volt metter.
Amazon seems to have the least expensive replacements.

My generator eu3000 will see its third winter in Western Washington and it does not start with the key. My wife needs the generator to run an oxygen machine, so the key start is critical. When I try the...

The EU3000 is a gel-pack (spill-proof) battery. Using a 10mm wrench or socket, remove the four (4) screws that hold the end cover on the machine.
Use a voltage meter and test the battery at rest (no load, not running). You should see 12 or higher volts DC. Record the voltage and then start the unit manually. Turn the ECO throttle "OFF" so the unit revs up to full RPM. You should see 14 or higher volts DC to verify that the charging system is OK.
The conclusion:
If the 12V test shows less than 10VDC, replace battery.
If the 14V test shows less than 12VDC, have a HONDA AUTHORIZED shop diagnose it for you.

Hope this helps.

No battery communications


You will get that message when the communications cable is not hooked up. It looks like a phone line and daisy chains from one battery to another and ends at the Matrix Control unit. If you have those installed and it still says no communication the system need service.

If you have a volt meter you can check the voltage from each battery at the plug. It should be 48 volts or more, usually on a fresh battery pack it will read 54.0+ volts.

Hope this helps,
