Stock up NOW for Christmas!
I don't really want to be the one to mention that Christmas is fast approaching!
But, batteries and chargers are one of the things which are regularly forgotten in the rush - and this causes great disappointment, as items cannot be used until these vital supplies are obtained.
Why not use one of our extensive, reliable, fast, and so reasonably priced suppliers... just check out the links in our right-hand margin... then you will know where to go to get up-to-date supplies [and no old dud batteries] and can get them in time for the celebrations.

Useful tip from our battery supplier...
Our battery supplier often gets asked - "How do I know how long to charge my batteries?"
The following is their useful and comprehensive reply to the above query:-
"Most of our battery chargers are automatic. Follow the charging instructions that came with your charger. For most battery chargers with LED lights the RED light on indicates charging in progress and the GREEN light on indicates charging completed. You can also calculate the approximate charge time using this method. Divide the desired charge mAh by the charge rate of your battery charger mA. For example to charge 1600 mAh rated batteries that are fully discharged it would take about 2 hours using a charger with a charge rate of 850 mA. (1600/850 = 1.88 hrs.)"
So there you have the definitive answer in a nutshell... I know previous posts covered this query, but none so succinctly!

Simple introduction to battery chargers...
Note that the charge current depends upon the technology within, and the capacity of, the battery being charged. For example, the current that should be applied to recharge a 12 V car battery will be very different to the current for a mobile phone battery.
There are several types of Battery Charger...
First there is a simple charger... which works by connecting a constant DC power source to the battery being charged. The simple charger does not alter its output based on time of charging, or the charge on the battery. A simple charger will be inexpensive, but there is a tradeoff in quality. Typically, a simple charger takes longer to charge a battery to prevent severe over-charging. Even so, a battery left in a simple charger for too long can still be weakened or destroyed because it has been over-charged.
As the name suggests... a timer charger is stopped at a pre-determined time. Timer chargers were the most common type for Ni-Cd cells in the late 1990s. Often a timer charger and set of batteries could be bought as a bundle and the charger time was set to suit just that type of battery. Battery technology is increasing capacity year on year, so an old timer charger will only partly charge the newer batteries.
Intelligent chargers are supposed to monitor the battery's voltage, temperature and/or time under charge to determine the optimum charge current at that precise moment. So output current will depend upon the state of the battery. Charging is terminated when a combination of the voltage, temperature and/or time indicates that the battery is fully charged.
For Ni-Cd and NiMH batteries, the voltage over the battery increases slowly during the charging process, until the battery is fully charged. After that, the voltage decreases, which indicates to an intelligent charger that the battery is fully charged.
The VARTA-Rayovac group sell "15 minute" superfast chargers for special NiMH cells. What makes these chargers different is that the charging process isn't only controlled in the charger, but also in the cells themselves. The special 15 minute cells are typically rated at 2000/2100 mAh and contain control circuitry that makes such fast charging times possible without damaging the cells' elements. All of them are capable of acting as a standard overnight charger if used with standard NiMH cells that do not have the special control circuitry.
Battery chargers for mobile phones come in a wide variety of connector-styles and voltages, most of which are not compatible with other manufactuers' phones or even different models of phones from a single manufactuer. You will require your instructions again!
Inverters take DC power (battery or solar, for example) and convert it into AC "household" power for running electronic equipment and appliances. In selecting the right size inverter electricity usage has to be calculated.

Extending the life of rechargeable batteries?
Just a mention of some current thinking ...
First please note when you first start your batteries on charge they will feel cool. Then check during the charging process, once they begin to get hot they are at the end of an optimum charging cycle and are charged.
Some electronic engineers are of the opinion now that battery conditioning is not necessary. They also contend that the idea that one battery charger is better than another because it has a refresh button is false.
Which argument you believe is up to you!
If you are searching for battery chargers... I'm being boring and recommending the same supplier again... try M D S.
I'm really impressed with their service which is quick and efficient. They send you an email, with invoice attached, as soon as your order has been processed and you are informed when it has been despatched. Plus, in the unlikely event of an item not being in stock... you are kept informed.
[I must admit I haven't had to contend with an item not being in stock, my items have always been available for immediate despatch!]
