I was just wondering if anyone knew if there was a "battery pack" available - like a totally different battery that plugs into the "charger" port of the Kyocera 7135? That way it would be useful on big trips or long periods of time instead of trading out the actual battery from the phone. Sorry if this has already been talked about, but I couldn't find anything on it. Any links or information on this would be awesome. Thanks.
About 2 minutes of cranking gives you around 6 minutes of talk time and considerably more standby time.*
The sidewinder charger provides a steady 6.2 volts while charging. The charger also contains a high-bright white LED light, which continues to give light up to 5 minutes after you stop turning the handle (30 seconds of charging = about 5 minutes of light). It provides enough light to read or walk with at night.
SideWinder dimensions:
Size - 2 x 1 1/2 x 1 inch
weight - 2 1/2 ounces
* Note: exact power delivery varies depending upon digital or analog networks, age and size of the cell phone battery, and how far your battery discharged before you decided to charge.
I made one with Radio Shack parts for under $20. I used 3 D Cell battery holders, a project case, a small plug, and an extension cable for their plug adapters. I cut the other end off the cable and wired it to the battery adapters with small wire nuts. It's a bit large so I used a fanny pack to carry it. You could substitute C or AA cells. I wanted the maximum run time.
Thanks for your ideas. After looking around I found a external portable battery pack (6300mah) and bought it. The only problem is that it is for devices that are 6-9 Volts and the battery for the Kyocera 7135 is 3.6/3.7 Volts. After reading other peoples tries with different Volts charging their phone I tried it on mine. It started to work and charge my phone but the next day my phone was off with no response I'm pretty sure it killed my battery. So, I put in my backup battery which worked initially. I started charging that one with my normal Kyocera battery charger and after over-night charging my phone has no response again! Did I kill something in my actual phone that charges the battery? Any responses on this would be very helpful. Thanks.
The standard external charger is 4.5 volts, which is why I selected 3 D cells. I also made the modification to the USB Sync cable which charges at 5 volts. The phone has a built in regulator that monitors the charge. NiMh batteries require smart chargers that communicate with the battery's built in electronics. I wouldn't recommend exceeding a 5 volt input, as the additional power must be disipated as heat. A 9 volt input will burn out the built in circuitry. If you must use a 6-9 or 12 volt charger, you must also use a regulator that reduces the voltage to 4.5 volts. Suitable regulators are available at your favorite electronic parts supplier.
Ok, that was very helpful information. I will definitely look into a suitable regulator for future use. But for now, any advice on what I should do to fix the phone if the built in circuitry went bad? Or a way to check that? Would any local repair shop or Radio Shack be able to fix something like this, or do I need to send it in to Kyocera? Any help is awesome - but having no phone for the last couple of days has been horrible
That's the bad part. You can call Verizon, or whoever your wireless carrier is. If you have the insurance, they will replace the phone after your deductible. If you're dealing directly with Verizon, you may have trouble getting another 7135. I read here they are trying to move users to the Handspring. You can try removing the battery for a few minutes, then charging normally. If it won't charge, you'll need to replace the phone. Another option is to buy one from ebay. If anyone else has a better idea, feel free to chime in. Good Luck!
Ok, I figured there was no easy answer - but thanks for all the info. And also, I'm a little uneducated on regulators and things like that. Any information on where and how to get those to regulate down to a 4.5V? A lot that kindof work like this convert from the wall outlet to whatever they are charging, but mine would need to come from the battery pack to the phone. Any advice on what I should get? Right now the battery pack has an output cord that has a connector for "PCS modular plugs" that can change for various sizes. Sorry if this was really confusing.
