*picard. cant charge non-rechargeable batteries. doing so will go you fireworks. it tends to explode. some just burn and explode.
*boybi. alkalines have 1700mah and above. regular batts have 400mah i think up to 800mah ata.
been using rechargeable batteries since 98, its for our 2way radios sa store. though ive used it in other electronic gadgets as well like digicam and cd players,etc.charging overnight (slow charger, para may longevity ang battery)then use from 5am to 8pm then charge ulit at night, for a year. hehehe. im using sanyo 2100s sa AA and sanyo 750/1000mah sa AAA as of now. other batteries have already been changed after a full year of use, some last a little longer. di maganda yung sony. ok yung gp, kodak and panasonic. also. i dont understand why the 2500mah (sanyo) dont last as long as a 1700mah or 2100mah when not in use. any ideas guys? maybe because it already has reach its peak , capacity wise?
though i have just purchased a new charger just last week. the brand is Ansmann, model is Energy16. its very nice. it automatically diagnose the batteries individually, yes each batt, then chooses if it needs to be refreshed before charging. it can also detect damaged cells then discharges before charging. stuffs like that. reason i needed something high tech is because we use the batteries daily. i need them in tip top shape. charger cost P8,000+.
accomodates AA,AAA, C, D and the 9V (e) rectangular battery.
regarding chargers. i would still recommend using slow chargers once in a while. it still gives the longest battery use. and fast chargers tend to charge only around 85% capacity of the battery. gets hot quickly too.
add ko lang. meron na ngayon available adaptor para sa mga AAA and AA batteries that can be used as a C or D battery. astig hehehe. theres a plastic casing with poles (size the same as C or D). wherein you insert the AA or AAA batteries inside it to be used as a bigger batt size. the reason here i think is minimized yung rechargeable battery purchase. pero maximize yung battery use.
