Laptop batteries

batt — Tue, 31 Jul 2012 14:40:22 +0000

The duration for which a laptop can be operated on a battery depends on a number of factors such as
1. Screen size – laptops with 15.6″ screens consume more power than netbooks with 10 ” screen
2. CPU used
3. Display settings – whether power saving has been enabled.
4. Number of cells in the battery pack

Batteries in clocks

batt — Fri, 16 Mar 2012 11:29:42 +0000

Most clocks are designed to work with one or two standard Alkaline batteries .
Typical specifications of these batteries are:
LR6
Size AA
Voltage : 1.5V
Using rechargeable batteries may be cost effective in the long term.
However, the rechargeable NiMh batteries available do not usually fit into the slot in most clock models, so rechargeable NiCd batteries, which are slightly smaller in size have to be used.

AAA Battery charging

batt — Sun, 26 Feb 2012 04:21:53 +0000

The usage of AAA batteries in various appliances is increasing due to their compact size. Manufacturers of rechargeable batteries specify the time taken for charging the batteries based on the charging current. For example for Vipow Ni Mh AAAA 1000 mAh 1.2V rechargeable batteries, the standard charging time is 15 hours at 100 mA. For a quick charge, a charging current of 300mA can charge the batteries in 5 hours.
For Uniross Dynamic Ni Mh AAAA 1100 mAh 1.2V rechargeable batteries, the charging time is 7 hours at 120 mA. These batteries are supplied precharged.

Certain models of battery chargers like BC 9009 from La Crosse Technologies display the charging current, voltage as well as other parameters, when the batteries are being charged and also indicate when the batteries are fully charged. In other models, an LED is used to indicate the battery charging status.

Sony Battery Charger with display

With most standard battery chargers, you do not get an indication of the time taken for the charging to be completed. This Sony battery charger provides a visual indication of the charge level in the batteries being used.

Voltage levels

batt — Thu, 31 Mar 2011 23:52:03 +0000

Most AA & AAA battery operated devices require a minimum voltage before they can operate properly. This voltage level is usually 1.25 V , though it can vary depending on the type and make of battery.

Battery vs AC powered devices

Batteries vs AC power

Most electrical devices are either powered by batteries or ac power.
Both options have their advantages and disadvantages
Batteries:
The device is portable
Less problem of loose connection

Disadvantages
If non-rechargeable batteries are used, running costs can be high
the torque for battery powered devices is sometimes lower than that of devices connected to an ac power supply.

Battery self discharge

batt — Sun, 28 Nov 2010 13:05:05 +0000

One of the main disadvantages of most rechargeable NiMh and NiCd batteries available today, over standard alkaline batteries is the high self discharge rates. If you charge rechargeable batteries to their full capacity and then use them after a month, you will often find that the batteries are drained. These batteries have to be charged again before they can be used.

The self discharge rate depends on the brand and design of the batteries, with some manufacturers advertising a low self discharge rate .
