How Do You Know When a Nimh Battery Is Fully Charged
Q: What does NiMH stand for?
A: The material is Nickel Metallic Hydride (NiMH) which has many advantages over other battery construction materials.
Q: What is meant by battery retentivity?
A: Older generation and batteries with other chemical brand-up were subject to a retention outcome. This is when a battery must exist fully drained earlier recharge or their capacity is reduced. The New Generation of NIMH batteries do not develop a memory effect and can be recharged at anytime during usage bicycle. When uncertain about bombardment accuse level or condition, recharge it.
Q: What is the mAh rating mean?
A: This is a rating of free energy storage chapters mAh = "milli-ampere hours". So if you are comparing batteries to a AA with a 2000 mAh rating, information technology will have twice the capacity of a 1000 mAh rating.
Q: What is the all-time application for NiMH batteries?
A: Nearly all applications where there is a loftier energy consumption and need, is where NiMH belongs. The well-nigh pop applications are digital cameras, flashlights, and toys. If you lot notice yourself constantly buying alkaline batteries for an awarding, then you should consider using rechargeable NiMH.
Q: How many times can a NiMH battery be recharged?
A: Lower capacity rechargeable AA batteries of 1700 up to 2000mAh tin can be recharged up to 1000 times in overnight tedious charge manner, while 2100 to 2400 mAh rechargeable batteries can exist recharged upward to 600 to 800 times in overnight boring charge mode.
The new higher capacity AA 2500 mAh rechargeable batteries have greater power capacity, but they can only be recharged approx 500 times in the overnight mode. Capacity improvement or quick charging will always decrease the number of cycles. Every cell bachelor on the market above 2100 mAh will have below 1000 charge cycles.
Q: What applications are not good places to use NiMH batteries?
A: Whatsoever state of affairs where the battery is non used within a 30 24-hour interval period or low energy draw devices, for instance smoke alarms, emergency flashlights, clocks, TV remotes, etc.
Q: Why won't NiMH batteries work in some applications such every bit fume alarms?
A: NiMH batteries self discharge about i% per mean solar day so if used in a low energy consummation or stand-past device, the bombardment volition only last about 90 days before requiring recharge.
Q: Tin I use a college rated mAh battery in my electronic device (i.e. 1800mAh vs. 2000mAh)?
A: Yes, the mAh rating will give you longer run times between recharges. The college rated mAh of a battery has no effect on electronic devices other than they allow longer term use.
Q: Why are AA and AAA batteries rated at 1.2 volts and alkaline batteries rated at i.5 volts?
A: In fact, over the course of their discharge, element of group i batteries actually average about one.2 volts. The master difference is that an alkaline battery starts at 1.5 volts and gradually drops to less than i.0 volts. NiMH batteries stay at about one.2 volts for near 80% of their discharge cycle. One time alkaline batteries discharge to fifty% capacity, it will be delivering a lower voltage than a NiMH bombardment.
Q: What yous NEVER desire to do with replaceable batteries?
A:
- Never mix batteries from different manufacturers
- Never mix batteries of different capacities
- Never mix batteries of different chemistries, i.e. NiCd, NiMH, Lithium, etc.
- Never DROP the battery if you lot can help it as NiMH batteries impairment internally quite easily
- Never store NiMH in the refrigerator
- Never expose to farthermost heat
Q: Do NiMH batteries lose capacity over time?
A: Yes, only zilch drastic. About 10 to 15% of the battery mAh capacity will be lost at the 400 to 800 recharge level. This will vary greatly because of bombardment and charger quality, forth with how the consumer treats their batteries.
Q: When I receive my batteries practice I demand to charge them?
A: Yes, before you use them for the outset fourth dimension, you demand to charge your NiMH batteries fully. Please note that for new NiMH batteries, it is often necessary to bike them at least three to v times or more earlier they achieve top performance and capacity. The first several times that you use your NiMH batteries you lot may find that they run downwardly (discharge) quickly during apply. Don't worry, this is normal until the batteries actually construction internally.
Q: Is in that location a divergence in chargers. i.e, fast, irksome, microprocessor controlled, etc?
A: Yeah, there are differences in the different chargers on the market place today. If the charger was designed and sold in the past couple years and specifically says information technology is fabricated to charge NiMH batteries you are probably okay. Nearly of the new chargers use a small computer chip to manage the charge and you should be getting at least 500 charges from your batteries. If not, buy a new charger. Some of the no name batteries sometimes have a short life. Fast chargers also tend to requite shorter battery life of less than 500 charges.
Q: How do dispose of quondam NiMH batteries?
A: This is an easy i! While it is condom and legal in most states to dispose of your NiMH battery in your regular trash, nosotros ever encourage recycling whenever possible.
