Nicad’s can be more finnicky with charge memory. Nickel Metel Hydride is very forgiving as far as recharging from half charge and the such.
The MaHa chargers with independant charge system for each cell is the only one I use. I have a 4 cell charger and a 10 cell charger. Each battery is independantly monitored and charged rather than averaging.
There is also a new family of NiMH called “low discharge” that have a much improved shelf life after charging… in other words you can pre-charge them and store them, unlike the typical NiMH.
MAHA’s next-generation nickel metal hydride battery the ‘IMEDION’.
Rechargeable Batteries have an inherent characteristic to release their stored energy in small amounts (this phenomenon is called ‘self-discharge’). This property is particularly noticeable in rechargeable batteries such as Nickel Metal Hydride Batteries etc. as compared to dry cell batteries, hence disabling rechargeable batteries from becoming batteries that ‘customers can use immediately after purchase’.
For this reason, rechargeable batteries couldn’t be used unless charged after purchase and so lagged behind dry cells in convenience. This new product’s main property is that it has introduced great improvements in self-discharge properties (residual ratio after one year of non use is 85%*4, in temperature conditions of 20 degree Celsius according to MAHA research).
Through this breakthrough development, MAHA has realized a rechargeable battery that can challenge dry cell batteries in user-friendliness through features such as making possible use immediately after purchase or once charged, its ability to be used anytime.
How MAHA reduced the self-discharge of NiMH Batteries.
Modern Ni-MH batteries consist of two metal stripes ( anode and cathode ), which are separated by a non-conductive porous plastic foil ( separator ). These three stripes are laid on top of each other and are winded to a coil. This coil is put in a metal can and immersed with a liquid ( electrolyte ). Then the metal can is closed with a cap. The self discharge of Ni-MH batteries is caused by three main reasons:
- the chemical decomposition of the cathode,
- the natural disaggregation of the anode,
- Impurities of the anode.
Now, how has the self-discharge in the MAHA IMEDION been reduced?
The chemical decomposition of the cathode has been reduced substantially by the use of an advanced NEW Technology that has been refined by MAHA.
As an additional benefit this technology increases the electrical capacity of the battery and reduces the internal resistance, which allows higher discharge currents than older NiMH Batteries.
Another advantage of the reduced decomposition of this alloy is the fact, that less strategic metal is needed to stabilize the alloy.
The anode has been strengthened by another new material, which reduces the natural disaggregation.
Additionally the separator and the used electrolyte have been optimized for low self discharge of the Imedion.
Low self-discharge - the key-advantage
What makes the IMEDION different than older NiMH Batteries?
The key-advantage of the Maha Imedion compared to usual rechargeable batteries is its extremely low self-discharge.
The IMEDION will Retain Capacity… Even After 12 Months of non-use
Once charged, Imedion retains its charged capacity even after 6 or 12 months of storage
(90% plus of Charged Capacity retained after 6 months, 85% Capacity after 12 months).
IMEDION batteries are pre charged and are ready for immediate use after purchase, straight from the pack. Just like Primary Batteries. There is no need to charge-before-use.
Once charged, IMEDION keeps its charge even if you store it for 6 or 12 months.
( 90 per cent of the charge after 6 months, 85 per cent after 12 months )
For a rechargeable battery this is a revolutionary advantage.
No more worries about the state of charge of your battery.
Just, charge them and keep them.
Even after months you will still have an almost fully charged battery.
In contrast to a disposable battery the IMDEION can be charged 1000 times. This saves the environment and your purse.
Thus one IMEDION saves the waste of 1000 disposable batteries.
