Guest nickweb Posted March 9, 2004 Report Posted March 9, 2004 Fom the Orange Website.... battery information By looking after your phone battery you can extend its life span. how do I use it? New batteries To gain optimum battery life, it is essential that a new battery is charged for before 16 hours before use . For the first charge, ignore the Battery full or 'Charging Complete' message and continue charging for 16 hours. New batteries achieve their optimum performance after 2 or 3 full charges. Conditioning a battery The battery should regularly be allowed to completely discharge (see table below), so the phone switches off, then the battery should be charged for the recommended period. It's advisable to allow a battery to fully discharge before recharging it. To do this, simply leave the phone switched on until it powers off. Lithium Ion & Lithium Polymer batteries do not suffer from the so called "memory effect" and therefore do not need to be discharged prior to charging. Battery lifespan As a general guide, batteries should be charged for the recommended period when the battery low indication shows, and overcharging may shorten a battery's life. All rechargeable batteries have a limited lifespan. Orange recommends that a new battery is purchased every 12 months. Talktime and Standby Talktime and standby times are typical times achieved, but will vary depending on usage. As a rule, five minutes talktime reduces battery standby time by approximately one hour. Use of any of the key functions, accessing the memory, applying the keyguard etc, will reduce the available charge. Also in areas of variable / poor coverage the phone constantly searches for the strongest signal, which increases the amount of power used, causing further drain on the battery. The use of "clock stop" SIMs improves battery standby. Talktime is reduced by 5% if Enhanced Full Rate is active, and increased by upto 30% if Half Rate is active. To gain optimum battery life, it is essential that a new battery is charged for before 16 hours before use . For the first charge, ignore the Battery full or 'Charging Complete' message and continue charging for 16 hours. Funny. i always thought that if the battery was full, the charging circuit switched off. And if it didn't, certain types of batteries can explode.. Can anybody shed some light on why Mr. O asks us to do this, when it looks like it isnt neccesarry? Nick
Guest squall Posted March 9, 2004 Report Posted March 9, 2004 the li-ion batterys in the spv range so have a charging circuit, but theres more to it than that. Each battery is split into cells, and although each cell can produce the required voltage to run the spv, you need several of then to produce the power required. so when you get a new battery and it shows fully charged, it only means some on the cells are fully charged, there could still be cells charging. once all cells are charged initially they drain at the same rate, so you dont have the problem after first charge. so basically charging for 16 hours ensures that all the cells in the battery are being used correctly, and wont harm the battery. Also the information in the orange link is on batterys in general, not li-ion specifically, strictly its not necessary do completely discharge a spv battery (its actually impossible to to thanks to the inbuilt charging circuit, however i still drain it most of the way every so often for good measure.
Guest nickweb Posted March 9, 2004 Report Posted March 9, 2004 cool.. So its better to do the 16hr thing? And drain it at least once a month (well, as low as it can go?)
Guest squall Posted March 9, 2004 Report Posted March 9, 2004 yeah wont do any harm, i drain it until the 2nd low battery message about once a month
Guest Rusty Posted March 9, 2004 Report Posted March 9, 2004 Or if you're on an E200, make that about once a day minimum, without even trying :) Posted from my SE GC75 GPRS Data Card!
