Your hedge trimmer sounds like it has died or is in the process of dying. A quick google search confirms that this can occur with Black & Decker hedge trimmers, although it does not appear to be wide spread. Because you didn't provide the model it isn't possible to give you a more specific reason why it has failed. My opinion is that when you were ...

Acid cell and Alkaline Batteries function by a process of controlled corrosion of two different elements which creates a voltage potential and a current if the circuit is completed. This process is in continuous motion from the day of manufacture, while it sits on the shelf in its packaging, while installed in the equipment during off/idle periods. It ...

Yes on battery removal. I've had better luck with name brand batteries. Before you pitch the lamp, try some vinegar, scraping off the scale ( I used a cotton swab soaked in vinegar) then neutralize with baking soda and finally rinse with water. I just resurrected a kitchen timer this way. I think ( but don't know), that the battery chemistry is more ...

Since you have an old car battery, the cost of damaging it by overcharging isn't much ($40?) and that would only happen if it got a lot of sun over weeks. A small home solar system might have thousands of dollars of batteries, so standard practice has long been for those to always have charge controllers. For small systems the cost of a charge controller ...

If you are willing to sacrifice a battery charger, you could gut the charging circuitry out of the charger housing and wire it as a battery dock.

It is generally always recommended that the batteries be removed from devices that are not in use. Even the device manufacturers recommend this. I'm not sure what actually leads to batteries leaking other than a failed seal. It is possible that a device exposed to wide temperature excursions may make the battery seals more prone to failure. There is more ...

For one, the magnetic field generated by the magnets are going to be small potatoes compared to the magnetic fields generated by the motor while in use. Two, battery chemistry is essentially unaffected by ferromagnetic fields of the magnitudes you'll encounter in everyday life. Thirdly, there exist specialty tools that have a big magnet on them out of the ...

Doubt it. I've carried several magnets right on top of my blackberry and all is well. I consider the drill heavier duty than a blackberry so I think the drill will be fine.

The "memory effect" is not typically a problem with modern batteries. The effect is generally "broken through" by large discharges, too, so if it's a battery for a power-tool, then it's a self-correcting problem. Modern chargers won't over charge so you shouldn't have a problem. Power consumption for continuous "trickle charge" is tiny. Opening your ...

If you can not find someone to take care of the acid for you, it is possible for you to dispose of it yourself. this page which references batterycouncil.org which most discreetly describes the process outlined here that states: Gather together all the acid you need to dispose of and put on some sort of concrete pad. The high acidity may harm grass and ...

I'm going to second mikes advice about wearing rubber gloves and safety glasses, especially if you can't guarantee that the container is properly sealed. If you get any on you, simply flush with lots of water, and apply a paste of baking soda and water to neutralize (I would flush first while someone else mixes the paste). For transport, just make sure that ...

Remove it from the basement while wearing safety glasses and rubber gloves and a rubber rain coat if you have one.If you can get a plastic storage container store it out side in that.You can try an auto supply store or battery specialtyshop to see if they will take it or anyplace that recycles metal as most take batteries.Some communities have a ...

The neck style battery pack typically held an extra 1-2 NiCad cells in that neck portion. With the transition to higher voltages, they want to make at least some change in design so you can't use the wrong battery like @Henry Jackson stated. But the main reason you don't see any is the way lithium-ion packs are constructed, yes they do still have a few ...

There have been a lot of changes in batteries for tools over the years. Different chemistries, voltages, capacities. Obviously the tool makers don't want you sticking a 20V lithium battery into an old 12V nickel-cadmium drill, so they make the shapes different. Maybe some of the discount manufacturers try to turn over their battery types regularly to force ...

There are several important factors when replacing a battery with a different one: Form factor: size, shape, terminal type and location should ideally be the same. This can be worked around in most cases, just make sure the battery will fit somewhere and that you can wire it properly. Voltage: must be identical Chemistry: the existing charger probably ...

As long as the battery supplies the correct voltage and amperage, yes, you can use it.

Replace the battery. Depending on who's responsibility maintaining the battery is, that's either you get a new battery or you call Verizon and have them replace it (which will be the easy way if it's their responsibility, and the expensive way if it's yours.) If the system is looking for a good battery, neither a dying/dead one nor no battery at all is ...

The fact that you saw smoke, means that something blew. While white smoke is not normally associated with the motors, you could have burned out the Brushes on the motor, (if its a Brushed DC motor). those are replaceable and, I would say the unit needs to be fairly old for the brushes to go (ie less than 3 months with heavy usage) Alternatively, you have ...

A deep cycle marine battery is a reasonable compromise between the dedicated sump battery and a light discharge car battery. The deep discharge potential is the problem: car batteries react poorly to getting used to the point of exhaustion, especially repeatedly. The sump use profile matters also: If the battery sump runs often and hard, buy the ...

You can get any number of configurations of AA battery holders. Mouser Electronics, an online electronics distributor has a whole page of them in their catalogue at AA Cell Holders Page from types that can accommodate 1 cell all the way up to 10 cells. Here are a few representative pictures of the ones available. These are available with solder tabs, ...

An 18V (Ni-Cd) drill I personally own has a rather strong magnet mounted directly over the battery. I rather doubt they're do that unless they were reasonably sure the magnet wouldn't cause battery problems.
