If you use any type of rechargeable battery, be it Li-Ion (Lithium Ion), NiCD (Nickel Cadmium), or NiMH (Nickel Metal Hydride), you will of course, require a battery charger to replenish power to batteries which have become depleted or drained. (batteries can become drained in two ways. 1) during use, and while idle). They can become drained while idle because all batteries discharge some of their power, continually whether or not in use. (Some people are not aware of that).

There are two main types of battery chargers on the market today. When we say “types”, we mean the charging processes that they operate with.

One process is called Timer-Controlled Charging and the other process is called Smart Charging. (Smart Chargers are also called Intelligent Chargers).

There is a difference in price between the two but more importantly, a significant difference in the way they each perform the task of charging your batteries.

TIMER CONTROL Battery Chargers

As the name implies, these chargers operate with an automatic shut off timer that is predetermined and built in during manufacturing. Charging time for different chargers range. Some charge for 4 hours, while others charge for 27 hours. Regardless of how long they charge for, the point is that they STOP charging AUTOMATICALLY at this pre-set amount of time. Timer Control Battery chargers are inexpensive. Very inexpensive but understand that all they do is charge the batteries in it for NON-NEGOTIABLE amount of time. This means that ALL The batteries inside it receive THE SAME AMOUNT of charge.  But what happens when some batteries need less, or more? What happens to the batteries that were only used a little bit and only require a small topping off? What about the batteries that were almost dead at the time of charge if they are then charged for 15 hours? What happens is this:

Some batteries become overcharged and some batteries remain undercharged. Let us explain here that batteries that have become overcharged, are ruined. Ready for the trash! Finito! GAR-baggio!

Batteries that are undercharged are not ruined – but they won’t give the use the run time they were intended to deliver. And sooner rather than later, they’ll need to be charged again. With all this, less than outstanding news, why would people still choose timer-control battery chargers when they buy a charger? Simple. It’s price!  Perhaps they paid so little for their batteries, perhaps they were FREE, that they don’t mind losing them to t he trash by accidently overcharging them in a timer-control charger. The price of this type of charger is much less expensive than smart chargers and oftentimes it’s just a matter of budget. All they can afford to pay is the price of a timer-control charger. To be honest, for the user who always waits until their batteries are completely dead, this type of charger is good. It’s just that many of us, if not most, don’t keep track of the juice left in each of our individual batteries. When they get a little low, we usually want to top them off


The best part about Smart Chargers is that they’re actually smart!! They have the ability to treat each battery placed inside it, individually. This means that each battery receives charge to the degree it requires it. One battery might be half full and only need to replenished half. Another battery in the charger might be ¾ empty and would need and receive ¾ the topping off power. This is quite an amazing technology! Yes, it costs more than does a timer control charger but no batteries can become over or undercharged in one. Over time, this higher price, greatly become absorbed (amortized) by the preservation of batteries it gives you.  Your entire battery inventory can no longer be at risk for ruin, with a smart battery charger!


A very handy little device that many people don’t often think about owning but when they do have and use one, boy, are they ever pleased to have it.

Whether you have non-rechargeable batteries (also called single-use, throw-away and disposable) like Alkaline or Lithium, or use Rechargeable batteries, it’s always a welcome thing to be able to tell what state of charge your batteries are in. “Exactly how much juice do those camera batteries I need for the music festival have in them before I head out? And that’s just what a battery testers’ role is. There are testers to test all battery sizes, including AA, AAA, C, D and 9 Volt and you can pick one up for a very small, and worthwhile outlay. Think about how owning a battery tester would benefit you or someone you know who either uses their batteries frequently, or, has most of their batteries sitting on the shelf, idle, because they hardly ever use them!

There are lots of websites selling batteries today. Some are not actually the stores themselves – they are portals, which can lure you there from search engines, making you believe they have inventory, only to lead you to other sites once you click on them and it’s these other sites that have, or have AVAILABLE, the batteries you seek. Every middleman along the way will receive a portion of your dollars spent on the batteries. A reliable battery supplier, starts with one who has their own inventory at their premises.
