By LSDPower, on March 1st, 2011 Battery charging is an uncomplicated task, but at times it’s not. NiCad and NiMH batteries are deemed as the hardest batteries to charge. However, the overcharging of li-ion and lead acid batteries is controllable. Basically, the concept of charging in based on the voltage and by simply setting a maximum charge voltage batteries can be saved. If you consult a connoisseur or an expert, you will receive knowledge regarding battery charging. According to the trends, there are few distinct ways of charging a battery.
 Hitech Battery Charger The first is overnight charging. Your battery receives sufficient power during the night and promises to accompany you throughout the day. Charging a battery at C/10 or below will turn out to be the most pocket friendly way of battery charging. So at 10mA, your 100 mAH battery will take approximately 15 hours to get recharged. Here, there is no requirement of an end-of-charge sensor and you will enjoy full charge. The newest batteries penetrating the market retain modern cells having oxygen recycling catalyst that assures 100% protection from overcharging.

By LSDPower, on December 7th, 2010 Experts, critics, specialists and even users have said a lot regarding the NiCd batteries that power a plane, however, the fact is, few advices are conflicting. Truthfully, there is a lot associated with these batteries and one has to be very careful while taking care of them.
If we attribute towards “memory effect” then it is the most perpetuated myth in NiCd history that occurs when only one part of the battery is repeatedly coming into use before the recharging process. Earlier, memory effect was common; however, it only occurs when charge and discharge cycles are of the same length.
 Type Of Battery Usually, the problems suffered by the cells are because of “voltage depression.” It is not caused due to charging a battery before the full discharge but by overcharging. The sole reason why people think that only a fully discharged battery should be charged, because then only you can notice the precise time it takes to get fully charged. The chargers generally used by the battery owners’ charges a battery at a constant speed and it’s your duty to remove the charger at the appropriate time so that it won’t encounter any problem because of the overcharging.
Remember, a recharge after a partial recharge demands less time so it’s better you charge the battery within a specific interval of time. We think that overcharging only reduces the life of the battery; however, it also diminishes the average current rate that a battery actually necessitates. Voltage depression is easy to cure but you ought to be a bit careful. By merely following the pattern mentioned below, you battery will never stumble upon voltage depression:-
Complete Discharge –> Complete Charge = Voltage returns to normal levels

By LSDPower, on July 27th, 2010 Good quality industrial battery chargers are deemed as apt for the batteries. But some users ask- why only good quality chargers? Well, this question sounds a bit weird but that is what people have to ask. If we answer this atypical question in a sophisticated and comprehensible manner then battery users invest their hard-earned money in buying a long-lasting and efficient battery. That is why to maintain that efficiency it is indispensable to buy a good quality charger otherwise you and your battery will have to face the repercussions. According to the statistics, 85% of the 70 million new batteries die before 5 years and it’s happens just because of the low quality chargers. This is the reason why it is suggested to buy a reliable and good quality charger.
 Battery Charger With the usage of low quality chargers, your battery will face:-
- Low Maintenance
- Contamination
- Vibration
- Undercharging/Overcharging
- Wrong applications
Firstly, it is important to evaluate which type of battery is apt for your job. What you invest on the batteries is not for the brand but for the high performance. So you have to think long term before you end up investing on a battery.

By LSDPower, on June 7th, 2010 Popular as NiMh batteries, Nickle-metal hydride batteries are secondary (electrochemical cells) in nature and similar to the nickel-cadmium cells. However, for the negative electrode, these NiMh batteries carry a hydrogen-absorbing alloy instead of cadmium. That is why NiMh batteries are better and more efficient companions than nickel-cadmium cells of equivalent sizes. If we compare lithium-ion cells with NiMh batteries then the volumetric energy density in NiMh batteries will be lower and self discharge capacity will be higher.
 NiMh Battery Disection With common AA cells, these NiMh batteries offer nominal charge capacities at a discharge rate of 0.2xC per hour but at a rate of 1xC, there is no significant difference though. In contrast, if we talk about the specific energy density then NiMh batteries are value for money products but not superior than Li-ion batteries.
Users who are desperate to replace their non-rechargeable batteries and fervently hunting for a replacement can certainly consider these NiMh batteries as a good alternative. Being a safer product, these NiMh batteries are apt for the personal use as they comprise hydrogen absorbing alloys in place of electrodes.
