Loses calls in the middle of a conversation. It is fully charged. Is it possible that the battery needs to be replaced every so many years?

Same thing happened to me. It turned out to be a corroded connection from the alternator that snapped off when inspected. The first thing to check is battery condition. A fully charged battery should be around 12.5 volts. When the engine is running the voltage should increase to around 14.5 volts. If it does increase then your charging system is working as it should and the problem lies elsewhere (possibly a battery that is past its best and needs replacing). If it doesn't increase the voltage, then chec the wires from your alternator (ther should be 2 wires) and follow these to the junction connector. This was where mine was badly corroded. I used more cable to bypass this connection and my problem was fixed. I then replaced the connections with new ones and all is fine. The bright yellow straw is pointing to the corrosion problem. Hope this is of help as totally replacing your alternator isn't cheap.

Without knowing the make and model of your flashlight, it's difficult to know whether you have a product with a replaceable battery. Providing that information would be very helpful.

In addition, you can try taking your light to a specialty batteries store--around here, there's a chain called "Batteries Plus." They have a large number of cross-reference books that identify all kinds of replacement batteries, and they may be able to help you directly in extracting your existing battery pack--or in telling you that it has been permanently sealed into your flashlight. Many spotlight-style rechargeable flashlights have replaceable batteries; conversely, smaller handheld rechargeable flashlights (the kind that look like they'd take 2 C or 2 D cells) are much less likely to have user-replaceable battery packs inside.

Good luck!

maybe the phone dies due to bad battery or poor battery connection.

remove the battery and clean the contacts.

consider buying a replacement battery

You will need to change your battery as soon as possible. You battery is causing all this. You are not using the phone and the charge of the battery is going through your phone's motherboard which is causing the phone to become very hot. It might also damage your phone's motherboard.

Try to use it firstly with AC adaptor(VSK0617) to understand that if it is working. The original battery pack (CGA-S302A) irreversibly loses approximately 20% capacity per year. So it is normal I think. Also, high charge levels and elevated temperatures (whether resulting from charging or being ambient) hasten permanent capacity loss for lithium-ion batteries. Think that shelf life+usage period+two years and other bad parameters decreases its life near 0.
As I said before,
Try to use the camera with its AC adaptor then change the batteries with new ones.
Hope that it will work.
This is the link of camera manual. May be you need to read the page 12.

A few things that cause drop out.

Poor vicinity for a strong signal
A low battery ***** must be fully charged The DC is only maintenance charging and eventually goes flat.
A damaged SIIRF CHIP caused by starting the engine whilst the GPS is plugged in.
A failked fuse to keep battery charged for maintenance in the DC charge unit.

Try recharging battery( or replacing it if 2 years or more of age)

If it's an original battery, call Canon, if you've only charged it once, I expect the camera is still under warranty. I've had lots of dealings with Canon Photography, the usually give extremely good customer service.

If it's a cheap one you bought of ebay - that's why!

if you have a volt meter, check the voltage at the battery before you start the engine and after the engine is running, before could be 11.5v after should be 13.5 or higher but no higher than 14.5, this will test the altenator, check the belt by pressing on the middle of the belt between the two pulleys the belt deflection should not be more than 1/2", if it is tighten and retest altenator

The batteries that are in most cordless phones, and even cell phones, have a "memory". If the battery is constantly being fully discharged from a lack of charging, or if it's used to being on the charger all the time, it will reduce the life of the battery substantially. You'll need to get a new battery, and try to make sure that the phone is placed back on its charger every night before you go to bed. This should allow the battery to receive a full charge each night to prevent full discharge and lengthen the life of your battery. I went through about 2 or 3 batteries once before I found this out. I'm sure that you'll find this helpful and it should save you a few bucks in not having to replace your battery as often. Please rate me accordingly, if it's not too much of a bother. Thanks and have a nice morning!

I looked up the battery specs for your phone. They are 3 X 200mah= 600mah battery packs. They should last 8 hrs talk time with the headsets. This style of battery pack in my experience only last about 1 1/2years and sometimes longer and "sometimes" shorter...much shorter. I bet you never had problems when you first got them. Basicly this "battery design arrangment" goes back many years before newer battery technlogy was developed. But designers still insist on using them even today. They are cheap to make. ****Time to replace them with new ones.**** Make sure you follow the mfgs charging instructions: "After battery installation, place the handsets in their base unit or charger and allow to charge for 16 hours before use. You can keep the battery charged by returning the handsets to their base unit or charger after each use. When the battery is fully depleted, a recharge takes about 12 hours. Average talk time on a fully charged battery is about eight hours depending on environmental conditions, standby time is approximately four days." Good luck
