Information and Product Offerings for 9 Volt Battery Chargers

As part of our commitment to quality customer service, we take this time to advice the following warning before we being offering information about 9 Volt battery chargers.

NEVER use 9 Volt rechargeable batteries in smoke detectors or carbon monoxide detectors! You must oly use 9 Volt non-rechargeable batteries in these devices to assure reliable performance. All rechargeable batteries, self-discharge much more quickly than non-rechargeable batteries.
Rechargeable batteries have far surpassed alkaline and other non-rechargeable batteries for many consumers and industry. The higher price tag they have is welcome and widely-accepted, due to the convenience they provide.
If you have, or intend to buy 9 Volt rechargeable batteries, you will want to protect and preserve that battery investment by using the correct charger, so here are some fundamentals to be aware of, before choosing one.

Most 9 Volt battery chargers will work for both NiMh (Nickel Metal Hydride) and NiCd (Nickel Cadmium) chemistries. NiMh and NiCd charge differently.  If you have 9 Volt NiMh and NiCd rechargeable batteries, please read on to discover the differences in charging processes for these two chemistries, and to learn about the different charging speeds and options available today.

The first thing to know, is that NiMh batteries (all sizes) are immune from “memory effect”. Memory effect is a term used to describe what happens to batteries that have been charged before first being fully depleted of power. In batteries that suffer this effect, namely NiCd batteries, recharging them before they are “dead”, causes the battery to “remember” their new smaller limit of power. NiMh batteries do not experience this. You may charge your AA and AAA NiMh batteries without concern for what amount of power they had left in them at the time of recharge.

In NiCd chemistry, there does exist this effect. Only recharge your 9 Volt NiCd batteries once they have been fully drained of power, in order to maintain their maximum memory capacity over their life span.

Now, we cover battery charging processes:
One type charging process is called Timer Controlled. The other process is called Smart/Intelligent Charging.  There are Rapid Chargers, Ultra Fast Chargers, 30 Minute Chargers, 15Minute chargers, Over-Night Chargers, Trickle Chargers, Universal Chargers, Solar chargers and more!

Let us share with you, the difference between Timer Controlled battery charging, and Smart Charging.

In a Timer Controlled charger, your 9 Volt batteries will all stop receiving a charge at the same time, when the unit, (which is pre-set at the factory with a timer), will shut off completely. A timer controlled unit treats all your 9 Volt batteries the same.It does not have the ability to detect the amount of charge each battery requires and “top it off” with just the right amount for that individual battery. Therefore, some batteries will be rendered undercharged by the time the unit shuts off (if they were almost dead to start with) while other batteries in it might be rendered overcharged (renders them useless) if they were not missing much power to begin with. Timer controlled battery chargers for 9 Volts are very inexpensive to buy but truly, are not the best choice in value over the long run, when you factor in the wasted  batteries that can come from using it.

Smart Chargers on the other hand, detect the amount of voltage or power that each battery still has within it and replenishes the depleted amount of power for each individual battery. Placing your 9 Volt rechargeable batteries into a Smart/Intelligent charger preserves your batteries longer, by recharging each battery individually as required.  Smart chargers are of course, more expensive than timer controlled chargers but well worth the price difference, since no batteries placed in it, will end up under or overcharged.

The types of battery charging process is fundamental to point out so that a consumer can be informed prior to their purchase. This way, they can better determine which type of charging process is right for them and their lifestyle. Having said that, there are still other valuable and educational matters to cover about battery chargers.
