Having the most advanced & environmental Ultra Low-Discharge Rechargeable Batteries (ULDReBat) is only 1/2 the picture. You'll also need the world's most advanced Smart Battery Chargers / Conditioners / Analyzers to maximize the battery's potential, lifespan & environmental factor. All chargers shown here work with UlDReBat. Many soft-charge, recondition, discharge, analyze, protect (from overcharging) & eliminate 'memory effect' from even the most problematic rechargeables. ULDReBat are best to be charged in non-quick mode.

Every year over 15 million batteries are producted & sold worldwide. Many are alkaline batteries which are disposed after only a single use. Fortunately, thanks to ongoing advances in both rechargeable batteries & battery chargers, alkaline batteries can practically be replaced with higher capacity, environmental-friendly, rechargeable NiMH or Lithium-ion (Li-ion) batteries. Rechargeable batteries are much less expensive to use - if you know the right ones to buy & the best way to use them to get the most out of them. Too many people just buy batteries arbitrarily and then have a bad experience and just go back to single use disposable batteries.
A few charger tidbits to keep in mind while choosing the right charger.
- Rapid charger = fast charger. These terms are interchargeable as there is no industry standard to differentiate between the 2. The amount of time it takes to charge a battery is dependent on the capacity of the battery being charged. For example, the same charger needs approx. 1 hour & 8 hours to charge up an NiCD AAA battery (180 mAh) & an NiMH AAA battery (1,500 mAh), respectively.
- A poorly-engineered battery charger can damage a battery by shortening its life & reducing its capacity. The most common cause of premature battery failure is overcharging. And the most guilty chargers are those 5- or 8-hour so-called "rapid chargers". These cheap chargers don't really have a charge control circuitry. Most of them use simplistic designs which charge at their full charge rate for a fixed period of time, typically 5 or 8 hours, and then shut off or switch to a lower "trickle" charge rate. This type of 'blind' chargers can shorten a battery's useful life after only a few improper charges. More advanced, intelligent chargers like the ones we present here can read the present charge level of the batteries & deliver only partial charge to top off. And these intelligent chargers with microprocessor-controlled do so whether their power supplies have been unplugged or not, whether the batteries are partially-discharged, completely-discharged, or mixed. Such charger conditions each battery individually.
- Trickle charge. Theoretically a trickle-charge is a charge rate that is high enough to keep a battery fully charged, but low enough to avoid overcharging. It's also called maintenance charge. Although most manufacturers do not recommend that you leave a battery in the charger for prolonged periods of time, many leave their batteries in the charger on trickle charge for days or weeks to keep their batteries "ready to use". If you know the rate of trickle charge that your charger puts out and it is around 1/10th of the battery capacity of less, then you should be alright if you are just going to do this occasionally. Smart chargers like the ones we carry will only send an occasioanl pulse charge to the battery once it is charged. They don't apply a continuous low rate of charge. It is better to fully charge batteries and then store them fully charged in a dark, cool place than to leave them on trickle charge for extended periods of time.
- Battery conditioning & reconditioning. When you intentionally discharge a battery down to a certain minimum voltage and then recharge it this is known as conditioning or reconditioning. This is particularly important to reduce the so-called 'memory effect'. Fortunately, NiMH is less susceptible to memory effect than say, NiCD so conditioning NiMH is less needed. However, reconditioning is very convenient for even NiMH batteries because non-ULDReBat come non-charged and they must be charged & discharged 3~5 times before they reach their full capacity. In addition, occasionally conditioning rechargeable batteries helps to ensure that they give you years of service and save you as much money as possible, before you recycle them & get new ones.
- What makes a charger a "smart charger"? Any charger that uses a microprocessor to control various aspects of the charging process (e.g. detect & adjust charge rate) can be considered a smart charger. In order for us to consider a battery charger a smart one, it needs to have a common charging feature known as negative delta V. Negative delta V is basically a technical method for a charger to know when a battery has reached its charge capacity & then shut the charging off, or sometimes switch to trickle charge mode. Other features that contribute to a charger's smart status are: temperature sensor, discharge & conditioning features, battery test features, and even timers to limit the total charge time.
