| 65845 | 2002-07-27 02:14:00 | Hi, Can anyone tell me if there's a place I can get an HP XE3 Li-Ion battery reconditioned in Auckland ? The battery should give between 3 & 4 hours power on a full charge, but at the moment if I get 45 mins I consider myself lucky. Thanks in advance. |

| 65848 | 2002-07-27 10:06:00 | There are some good tips in this (pressf1.co.nz) post. | Susan B (19) | ||
| 65849 | 2002-07-27 10:13:00 | But the tips are not particularly relevant for Li-On (Lithium Ion) batteries, they don't suffer from memory effect. But they are expensive. And I wouldnt freeze them either. | godfather (25) | ||
| 65850 | 2002-07-27 10:32:00 | Oh. Sorry. I thought they would be similar but obviously not. Thanks for putting me right godfather, it's just as well I've got you following me around sometimes. |

For long life you dont just buy rechargeables and put them in, you perform capacity tests and match the individual batteries in the banks for size. This is why proprietry battery packs are often quite expensive. |

| 65852 | 2002-07-27 12:25:00 | These batteries do suffer badly from hysteresis most batteries now are of the hydride type which don't suffer from this effect. You will find most cellphones now have this type of battery. You can restore them by shorting the + & - with a resistor to take them to a completely discharged state this should then recharge fully.

You will find most > cellphones now have this type of battery . Which type? Unsure which ones you are recommending to be discharged All my cellphones (latest model) have LiOn When LiOn get past their best they exhibit lack of capacity, which is not usually able to be restored by a discharge . Hydride suffer less from problems, but LiOn have even less problems? |

| 65854 | 2002-07-27 13:41:00 | Sorry I was unclear the Ni-cad can be discharged. The Lithium-Ion do have very similar characteristics with the Metal Hydride but the hydride has a bit more grunt with higher discharge capabilities and a faster charge rate but are a bit heavier than the Lithium-Ion. The hydrides were used a lot in electric cars because of the above capabilities. Well thats enough about batteries one things for sure no matter which one you like to use they are hellishly expensive. Regards Trev. |
