nagulat ako sa tanong mo, dr. d; wala pa akong nakitang lithuim batt na nonrechargeable. by common knowledge, mercury batt should not be charged, at pati alkaline batt din. n-c batts are rechargeable, etc.. a cp batt is similar to the batt of epass. p999 na ba ngayon ang promo price? baka more or less, p100 ang charger, the parts are installed inside a cigarette lighter plug. i would prefer the setup w/ a charger, of course, sa iba, bulky-looking ito. kung kailangan ipost ko ang schematic diag dito, sa next reply na lang. tatapusin ko yong thread about gtoil. page 30 na ako. informative na, komedy pa. hehe
