What does 600mah mean on a rechargeable battery?
mah stands for milliamp hours. It’s a measure of the amount of energy a battery or battery set can store. Thus a 600mah battery can store more energy than the 400mah battery. More stored energy equals more talk time between charges.
Is NICD or NiMH better?
Nickel-metal hydride (NIMH) batteries have a higher capacity than nickel-cadmium (NICAD) batteries, which means that they can generally power your device for longer. Finally, NiMH batteries are much better for the environment than their NiCAD battery counterparts.
How long do NICD rechargeable batteries last?
The normal lifetime of a Nicd battery, in a typically harsh environment back-up power application, is in the range of 15 to 20 years. Occasionally, Saft batteries exceed their normal life expectancy by more than 35%.
Can I replace a 300mAh battery with a 600 mAh battery?
You can replace your battery with a slightly different mAh capacity, as long as it is the same voltage; we would recommend choosing your replacement batteries with the nearest possible mAh rating. It is not recommended to replace your batteries with a much higher mAh capacity.
Are NiCad batteries good?
Nicad batteries are very robust. They are good for working in extreme environments, such as cold or hot weather. They also have a longer life cycle than NiMH or Li-ion, with about 700-1000 life cycles. They are very robust for high output deep discharge applications.
Should NiCd batteries be left on charger?
These batteries work best with a pure DC voltage. After full charge, the NiCd battery receives a trickle charge of 0.05–0.1C to compensate for self-discharge. In spite of this, it is best not to leave nickel-based batteries in a charger for more than a few days. Remove them and recharge before use.
Are NiCad batteries any good?
NiCad batteries contain Cadmium, a highly toxic ‘heavy’ metal. As long as NiCads are kept sealed, and never short circuited or severely over charged, NiCad batteries are perfectly safe to use, and do not vent toxic material. If a NiCad battery is treated well, it should last to the 1000 cycle mark.
