Halogen Lamp Pack
Why do my halogen "puck" lights keep blowing?
I have a string of 8 120/115V 20W "puck" light bulbs in my kitchen. They've been installed for over three years. Suddenly one of them was blowing more than the others. After about 4 replacements in 4 weeks, I came home to find it had blown again and the one next to it (last one on the chain, if it makes a difference) was twice as bright as usual. It blew shortly thereafter. I replaced both AGAIN (you know, one LAST time) and this morning the one that had been blowing a lot is blown again... and taking note, the other lamp seems brighter, though I can't be sure since it is brand new and could look a bit cooler.
The lamps are in parallel, so voltage should not be changing. I also have not handled the bulbs with my fingers at any point, taking care to use a cloth. Line voltage is 119. Bulbs are listed 130V 20W, G8 35mm, and all come from the same 25 pack I bought back when the pucks were installed... so other bulbs from the same batch have been used and not blown so often.
Only can think of a couple of reasons for this to happen. One being that after three years the socket could be going bad from all the bulb replacements and heat that was generated. The other being the brand of bulbs. If they are a bargain pack, they may be inferior. All bulbs are not equal. Check the voltage at the bad socket to see if you are getting constant power. If they seem good you could try putting them on a dimmer or get a lower wattage bulb. My guess is that there is a wiring issue at the first puck you mentioned, either at the socket or link to others on the strand.

how to repair the laptop battery cell
how to repair the laptop battery cell.
Points and then encountered trouble: it was soon filling power (twice as fast than normal), in the course of discharge to 70% of the time will suddenly prompt "The battery is dead, please insert the AC power supply" warning capacity to show an immediate 5%. The beginning of a long time thought it was not using the battery leads to memory effect, we should do like a few of the deep cycle. But after several full charge, after release and found that the improvement is very small, only about 45 percent take power, with half an hour, we still have the problem. The largest may be the Inspiron 1520 battery pack in more than one section or "black sheep" in trouble, have to pull it out!
Red several times in the subsequent discharge cycle every place is full of electricity and have finished after the battery power to open, measuring the voltage of each battery pack to find a group of "different": the per-charge when it voltage to reach 4.2V or even more than the first, leading to cessation of the entire VGP-BPS2 battery charge, and discharge when it was first to reach 3.6V or even less, is a typical decline in capacity. And the largest of which may still be a battery problem. This group of cells separated from the measurement of voltage, respectively, found that a battery voltage is low, only about 3.2V, a separate charge of their voltage quickly reach 4.2V, less than a minute of time, The A1185 battery basically has no capacity to speak with a light bulb when the discharge was found, it has the fundamental output current that can not provide even less than 1mA, measuring its resistance, has reached more than 2K seems to have been scrapped.
As a result of a "shock therapy" after the restoration of the normal cells, but not charging voltage reached 4.0V, it seems that it is "the pot boiled dumplings - do not put out an electric" soldering it back a battery discharge followed by the use of time of up to 90 minutes, has been near normal level of the battery.
However, when the charge is quickly filled, and disturbed mind up soon. Was a discharge, it is less than half an hour, open a test, just fix the bad and the battery.
Not always have to use a "heart to recover," ah, so the value on the lost.
This section of the final decision to do a battery operation, and then they can not, then replaced the batteries. Peeling of the batteries, removed the insulation near the cathode cap and found a slight corrosion around, but I do not like battery leakage and traces, as well as save. With halogen lamp from the battery positive and negative, there is no response Taking into account the previous "Anatomy" the same symptoms when the batteries are inside the battery with the battery cathode output between cathode cap (the pressure on, not welded) oxide occurred, resulting in increased resistance and end-of-life battery , and the internal battery is still good. Oxide layer in the case is not serious as long as the battery cap to strengthen the internal contacts and battery resulting in the battery does not leak if damaged can be restored. The simplest way is to step up the battery forceps are negative (one pad insulation film), while measuring the inspiron E155 battery output voltage (or current), while vertical extrusion batteries, once the battery output voltage is increased, the current increase (the change is often the jumping in nature, relatively large changes) to stop immediately, the battery will be able to repair.
The top edge of the battery cathode cap next to the mouth ventilation valve with cutting pliers, then immediately measured and found that the battery has been restored, the output current increases immediately. In order to insurance purposes, the battery cap in the week between the edge of the chisel a few more in order to increase the contact area to ensure that the use of effects.
The battery to re-wrap, solder back to the XPS M1210 battery pack, charge, discharge. The use of time to reach more than 90 minutes.
Again measured with test software and found that the current capacity of smaller 38.88Wh from the original into a 32.07Wh, a decrease of nearly 20 percent, but this is the real discharge process, there is no jump of dropped. After several red discharge cycle, the capacity has increased by some. Use has been made to the current two months, everything will be all right.
