NiMH batteries have become popular for powering many electronic devices. They come in high capacity and lower capacity sizes. NiMH batteries are rechargeable and can be recharged using a standard NiCad battery charger or with a charger specially made for them. If a NiCad charger is used it will take longer to get a full charge since NiCads have a lower capacity. NiMH chargers are obtainable in what is known as smart charge or in timer controlled types. The timer controlled charger can be set to charge for a fixed length of time and will then shut off. Smart chargers do not charge for any fixed period but rather keep charging till the battery is completely charged before shutting off.

So some users will opt for the fixed time charger so as to save some money. There is some saving to be made on the purchase price but there can be problems, due to partial recharging, as Buy Molly Online the timer shuts down the charger before a full charge has completed. This is annoying and for this reason most users will be well advised to get a smart charger at the somewhat higher price.
However if only lower capacity batteries are to be used a fixed time charger can perform this function quite well. For high capacity batteries a smart charger is definitely the best choice.

Several battery companies now make low self discharge batteries. These can keep 70% to 85% of their capacity when stored for a year at room temperature. In the same period of time ordinary NiMH batteries may lose 50% or more of their charge. LSD NiMH batteries are rechargeable just like normal batteries and can be recharged using the same battery chargers.
Their main difference is much longer shelf life and a higher price. These LSD batteries can be charged up to 1000 times which is double the figure for ordinary NiMH batteries. This makes them very economical for long term usage.
