ສໍາລັບການ cordless ເຄື່ອງມື, ພະລັງງານໄດ້ຖືກກໍານົດໂດຍທີ່ແຮງດັນໄຟ: ແຮງດັນໄຟຟ້າທີ່ສູງຂຶ້ນ, ພະລັງງານຫຼາຍແລະ torque ເຄື່ອງມືທີ່ມີທີ່ມີຢູ່.

ໃນຂະນະທີ່ພະລັງງານຫຼາຍແລະ torque ອາດຈະເບິ່ງຄືວ່າຄ້າຍຄືບາງສິ່ງບາງຢ່າງທີ່ທ່ານຕ້ອງການ, ມີການຄ້າ, ການແຂ່ງຂັນທີ່ຈະເຮັດ.

ມີເຄື່ອງມື cordless ແຮງດັນສູງ, ຄຽງຄູ່ກັບການພະລັງງານເພີ່ມເຕີມ, ມາຄ່າໃຊ້ຈ່າຍເພີ່ມເຕີມແລະນ້ໍາເຄື່ອງມືເພີ່ມເຕີມ.

ນີ້ແມ່ນການປຽບທຽບປົກກະຕິສະແດງໃຫ້ເຫັນຈຸດທີ່.

A ປົກກະຕິ 9.6 Volt ເຈາະ cordless ໂດຍປົກກະຕິຈະມີນ້ໍາຫນັກຢູ່ໃນບ້ານຂອງ 3-1/2 ປອນແລະຄ່າໃຊ້ຈ່າຍໃດກໍໄດ້ຈາກ $35 – $150.

ໃນຖານະເປັນການປຽບທຽບ, ເປັນ 19.2 ເຈາະ Volt ໄຮ້ສາຍສາມາດມີນໍ້າຫນັກເຖິງ 10 ປອນແລະຄ່າໃຊ້ຈ່າຍໃນລະດັບຂອງ $125 – $300.

ຖ້າ torque ເພີ່ມຂຶ້ນແລະພະລັງງານຂອງ 19.2 ເຈາະ Volt cordless ເປັນສິ່ງຈໍາເປັນກໍ່, ຄ່າໃຊ້ຈ່າຍທີ່ເພີ່ມອາດຈະຕົກເປັນມູນຄ່າມັນ. But if you are using your cordless drill to occasionally drive screws in your home, ເປັນ 19.2 Volt cordless drill is probably not worth it since it is harder to use (since it is heavy) and money not well spent. ຂ້າພະເຈົ້າ

f you really do not need the additional power, a cheaper, light-weight cordless drill will probably suit your needs much better.

Number of Batteries
Another point to consider when buying a new cordless tool is the number of batteries that come included with the tool.

If you plan on using your tool for extended periods of time or often, you will want to only consider tools that come with two batteries.

It is very frustrating when your batteries dies in the middle of something and you have to wait a couple of hours for the battery to charge before you can get back to what you were doing. When you are purchasing a tool, make sure it comes with two batteries.

If it does not, look up the cost of an additional battery and include that when you are comparing costs between tools.

Battery Type
Two types of batteries are for sale for cordless tools: Lithium Ion (Li-Ion) and Nickel Metal Hydride (NiMH).

Do yourself a favor, do not purchase a cordless tool that uses NiMH batteries. Yes, it may be cheaper, but it is cheap for a very good reason.

NiMH batteries have issues with memory problems (they need to be completely discharged before they are recharged or they lose charge capacity), they do not last for as many charge cycles (the batteries die quicker), and they are lower power than equivalent voltage Li-Ion batteries.

Battery and Tool ການ​ເກັບ​ຮັກ​ສາ —
Even when your cordless tool is off, it will draw a small amount of energy from the battery.

While the amount of energy being drawn is slight, it can add up to a significant amount over the course of days, or weeks.

So when you put away your cordless tools, be sure to remove the battery; this will help ensure that the battery is charged when you need it.

Do not keep your battery in the charger for extended periods of time. While there are some chargers that claim to besmartabout this, but as a rule storing your cordless tool batteries in the charger will lead to them dying sooner than if you do not. When storing your batteries avoid storing them in heat and cold. Cold weather will not harm your battery long-term, but it will decrease the amount of available power when the tool is being used.

High heat can permanently ruin the batteries of your cordless tools.

Avoid high heat, and do not charge your batteries in an area that is overly hot, this can permanently damage the battery.

Charging Your Batteries
Many higher-end cordless tools now come with advanced chargers that allow the battery to be charged in a very short period of time; often in about 15 ນາ​ທີ.

ສໍາ​ລັບ​ການ​ສົມ​ທຽບ, a standard charger can take up to 3 hours to charge the battery.

If you need a quick-charging battery for your tool, look into the charging options that are available prior to getting a cordless tool.

Pick a Brand
An easy way to avoid problems with battery availability is to decide on a battery size and brand and stay with it.

If you consistently purchase the same brand of tool with the same battery size when buying drills, trim saws, reciprocating saws, screwdrivers, ແລະອື່ນໆ, you will be able to share batteries and chargers between all of your tools.

This will increase the number of available batteries and it ensures that you will never run out of charged batteries.
