- Q: 3.6v lithium battery how to become 36v battery pack?
- 10000mah can be made up of five 2000mah batteries in parallel, 36V 10000mah by 10 10000mah battery pack and made together.
- Q: Hi, i have Acer 3830TG This laptop is amazing performance wise and also battery wise but only one disadvantage that is quite crucial to my purpose of use is the built-in battery.I often use the laptop to play high performance required games for an extended period of time and this is done while being chargedI found out that constantly fully charged battery will not last long Is there a way to be on AC power and not charge the battery, (laptop only running on ac power and battery is disabled) thanks in advance
- Most laptops will allow you to just remove the battery and run straight off of ac power. Having had numerous batteries go bad on me in my lifetime, I'll be the first one to tell you that having it constantly plugged in definitely kills them.
- Q: Hi,I was wondering, does the Xbox 360 rechargeable battery pack last longer than regular rechargeable batteries?Thanks.
- Depends on the rechargeable battery, but in general yes.
- Q: I have 3 Phottix battery pack for my 3 Canon Speedlite 600ex-rt and I am wondering about getting a full charge out of them. When I am charging them up after a while the red light will turn green showing that they are done charging, but if I unplug them for a second or two and plug them back it the light will be red again for another 10 minutes or so. Is this helping it get more of a charge or not? Thanks
- No it is best to charge until the light changes green and leave it at that. Many rechargeable have memories and the frequent charging cuts done on the entire life of the battery. It is best to use that age old rule regarding batteries--------READ THE MANUAL.
- Q: Hi, I've been trying to google-educate myself but I want to make sure of what I'm doing and ask for some expert advice, if we've any in the audience. :) I have a battery case that takes two AA batteries (energizer if that matters), I've checked on my voltmeter and I believe it gives a DC current of 3.20v (if that's way off I may be using my voltmeter incorrectly) And the LEDs I have are 5mm Nexxtech LEDs, which from searching I've found this information on them: 5mm (T1 3/4): Forward Voltage 2.2 V, Forward Current 10 mA (max 15 mA).Now I want to hook up 4 LEDs to this battery pack, to be continuously illuminated. I have also got a pack of 1/4 watt 5% resistors. On the back of the pack it lists a whole slew of specs, apparently there are two of each type, but I'm not sure what the numbers mean, or how to differentiate which resistor is which. (see the summary of
- The battery pack you have is +3.2 volts, which is correct since *unloaded* batteries are typically 1.65V and are 1.5V when loaded down. Now in order to hook up (4) LEDs with a (minimum) forward voltage of 2.2V, you will need 4 * 2.2V 8.8V (minimum) as a voltage source. Therefore you would need (3) dual AA battery packs that are connected in series to get 9.6V to work properly. Next you will need to control the current thru each of the LEDs that are also connected in series. The resistor would be need to be the voltage divided by the current from Ohm's Law as follows R V / I (9.6V - 8.8V) / 10mA 0.8V / 0.010A 80 ohms With this solution you can use (1) switch to turn off all the LEDs. An alternate way to power the LEDs is when each of the (4) LEDs are in parallel to the single 3.2V source. Since the voltage drop of each LED is 2.2V, the resistor for each LED would be R V / I (3.2V - 2.2V) / 10mA 1.0V / 0.010A 100 ohms Now you would need a switch to the batteries that is in series will all (4) LEDs that are in parallel to each other with their separate 100 ohm resistor. Notice that the batteries will not last as long with the LEDs in parallel as they would with the LEDs in series. The series combination is more efficient, but requires a higher voltage. LEDs do not give off heat, but the resistor might. However, the current of 10mA is not enough to create any danger.
- Q: I have replaced the ni-cad cells in my 18V bosch drill with li-ion cells (respecting the voltage and wiring).Can I use the original ni-cad charger?The charger knew when to stop charging with the ni-cad battery, will it do the same now?Thank you.
- If you can stop a 300 ft pound impact wrench it isn't worth owning unless there is a torque setting and you have it on the weakest setting. Regarding the batteries, tools are usually one or the other meaning that if it comes with NiCad or Li Ion there is no switching to the other or why would they produce two batts for the same device. If you HAVE a choice Li ion batts are very light in weight by comparison to 18V NiCads are. I have two cordless drills I use/used. One is an 18 volt DeWalt with NiCad and the other is Rigid with Li Ion, they are both the same relative age ( maybe 6 months between the two) . My DeWalt is still going strong 8 years later, but the Rigid with compact Li Ion batts are BOTH dead and gone: no recharging will kick them over. I called customer service to see if I could find out whether it was the charger or the batts. They weren't any help so I got another charger and the batts came up as defective. At $100 each I am in no hurry to replace them because the DeWalt is still going strong. So I am convinced Li Ion is one I personally will avoid going forward.
- Q: About how long would a (5800mAh) Lithium Ion battery pack last you, in hours/minutes?
- You can’t expect a general answer like that. Because battery time depends on your CPU : how fast it runs, what type, what kind of power saving features it supports etc. GPU : Whether you have an integrated or dedicated graphics card Monitor type Size : LCD or LED and what size Average Monitor brightness Hard Disk speed : 5400 RPM or 7200RPM Wireless devices : whether you have Wi-Fi and Bluetooth ON or OFF What type of applications you run : Whether processor is under load or not Power profile : Whether you are running in power saving mode or not. Depending on the above the time can vary a lot ! One more thing, you can only compare the mAh rating when the voltage is same. For actual power you need to compare the v * Ah Whr (Watt Hour). I have a 11.1v 4800mAh ~ 54Whr battery . It will last around 3 hrs 15mins in Vista under power saver profile, when doing normal work. Specs : T7250, 8400M GS, 120GB 5200RPM, 13.3 LCD display at medium brightness, Wi-fi + BT ON.
- Q: What should the UPS battery pack remove and reassemble?
- Place the battery in the upright direction and prohibit the use of the battery.
- Q: I have a Kin 2 phone by verizon and it has purple x's on the battery pack. Does the purple x's mean water damage or not???
- Yeah it means water damage. That way if you try to bring it back and replace the phone, they'll know how you ruined it.
- Q: as far as dimensions go, is the 12 cell battery bigger than the 6 cell or does size not matter? What is the difference- 12 cell last longer when charged up? thxI plan on buying one for my Sony laptop (PCG-3B4L) and want to make sure it fits. DC 19.5 V, 11.1 v 4400mAhBattery-VGP-BPS13/S
- The capacity of a battery pack is measured in mAh so as you have mentioned a 4400 pack will last X minutes on a single charge. A battery pack of say 8800 mAh would last 2 x X minutes (approx) per single charge. The lifetime of each would be similar The physical size grows dependent on the number of cells as will the weight so more cells more capacity more weight. All cells are not created equal. A really cheap battery probably uses cheap poor quality cells, use a USA based supplier with a warranty worth the paper its written on and you should be just fine. Sony charge a lot more than these guys. Check the link for one such USA based company.
