NiMH Rechargeable Batteries
Posted: Sun Mar 02, 2003 5:10 pm
My Logitech cordless optical mouse eats batteries like crazy. Every 2-4 weeks, it requries a new pair of AA batteries. I've been looking into NiMH batteries to be used with my mouse, but had some questions concerning the technology. I went and checked out Fry's selection of NiMH batteries and was unsure what brand, power, charger, and etc. to buy.
1.) I've seen NiMH batteries labeled 1200 mah, 1600 mah, 1700 mah, 1800 mah, 1900 mah, 2000 mah, and etc. What do these numbers mean and are higher values better?
2.) There are so many chargers for these things. Some that are quick chargers which take 1 hour to charge and other charges that take 7 hours to charge NiMH batteries. Is there any disadvantages to the quick chargers, like if they would reduce the life or how many times you can recharge the NiMH batteries? Any good brands you would recommend for a charger?
3.) Do NiMH batteries have memory in them like how Alkaline rechargeable batteries do. Where you have to charge the batteries when they are completely discharged or else you will decrease the life span of them when you charge them often? Or can NiMH batteries be charged whenever they are low and will have no effects on the lifespan of the batteries?
Thank you for any info or websites you can provide. I don't want to spend more than $30-$40 on a charger and a set of 4 AA NiMH batteries.
