| 456544 | 2006-05-21 03:46:00 | Just yesterday, my Casio Graphics Calculator fx-9750G PLUS flashed the low-battery sign. To be on the safe side - my trigonometry exam is coming! - I plan to pop by either New World or Pak N' Save and hunt for 4 AAA batteries. However, should I go for Heavy Duty or "Light duty" or alkaline ones? The batteries that come with this calculator are "Industrial Heavy Duty", manufactured by Panasonic. Besides, which brand of batteries should I go for? Energizer? Or any generic (e.g. Transonic) one will do? Cheers :) |

| 456546 | 2006-05-21 03:59:00 | Due to the importance of your exams, I would buy alkaline batteries and the best I could afford. However on saying that, your calculator shouldn't take much to power it so perhaps this approach will be an overkill. I would be a bit cautious about using Ni-cads as these have a cell voltage of only 1.25v, not 1.5v. Check the milliamp (ma) draw on the backplate on your calculator and go from there. BURNZEE |

And unmless you have 2 sets, you will be out of action while you charge them. Alkalines will last a long time. DSE's have about the best value for money on (their own brand) alkalines. |

BURNZEE For your info: Rating: DC 6V, 3V == 2 Supply 0.06W (Since P = VI, current is 0.01amp) The batteries that I now have in my calculator had only been slapped in last year. I will have a look at my area's DSE' alkaline batteries, Graham :D My calculator doesn't support solar power, Speedy :P Cheers :) |

| 456549 | 2006-05-21 04:35:00 | That 6V is for an external supply. It uses 3V, so things look even better. ;) Obviously, the cheapest type the manufactuters could buy that month were "Industrial heavy duty". Alkaline will last much longer. | Graham L (2) | ||
| 456550 | 2006-05-21 04:54:00 | my old rule of thumb....Alkaline last 3 times long than "heavy duty" but only cost twice as much. | tweak'e (69) | ||

| 456552 | 2006-05-21 10:44:00 | I just popped a brand new pack of Energiser E2 Max's into mine, and then I left it somewhere. Grrr. | Growly (6) | ||
| 456553 | 2006-05-22 11:26:00 | All good. I went to The Warehouse and bought 1 4 x AAA Energizer batteries pack for $7.50 bucks. I wonder why Bond and Bond is charging customers $10 buck for the same product. :illogical Cheers :) |
