in the 2003 HALO-jumping special forces movie operating in Africa : you wonder how long laptop batteries can last in the jungle – and there is a special company that produce such durable machines whose employee swear a Wonder even to be working for .. while whimpy-me has to dure with smaller devices like the portable label-printer I have mainly to stick dates on HDD hard-disk drives . I use it rarely so when-ever I try to re-use it : its four AA-size batteries are almost-drained .
come Sanyo’s rechargeable eneloop Ni-MH nickel-metal hydride batteries which entered the market in 2005 and became a house(with a man’s garage)-hold name like Kleenex for power-retaining batteries, while the larger Japanese competitor Sony offer a similar line – and in my experience can be charged together in the same charger . their recharging capacity has been steadily increasing every-other year since, and their latest model before this was introduced 2013 with power of 2000mAh, and can be recharged 1800 times . but again a larger Japanese competitor Panasonic who acquired majority of stakes in Sanyo end of 2009, is now beginning to put their own name on these life-saver product – thus Panasonic eneloop from models manufactured from this year 2014 :
above white Eneloop 2000mAh which can be recharged 2100 times, for W12,300
then below black 2550mAh to be recharged 500 times in comparison, at W20,100
both introduced June 2014 and price quoted for a set of four AA-type batteries, at larger discount On-Line shopping malls which is the cheapest – even than Duty-Free Shops
