## Questions & Answers

**Q: Is this battery rechargeable?**
A: yes. It is battery for medical device use. I'm using mine in a Welch Allyn ophthalmoscope.

**Q: Will it fit a 71050 otoscope?**
A: That is the handle I bought it for & it's given great service.http://www.allheart.com/product.aspx?p=wa71050

**Q: what is the expiration date on the battery?**
A: My battery does not have an expiry date but it is working fine. It charges well and holds the charge for along long time.

**Q: What is the battery capacity in milliamp hours?**
A: A battery with a capacity of 1 amp-hour should be able to continuously supply a current of 1 amp to a load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged. In an ideal battery, this relationship between continuous current and discharge time is stable and absolute, but real batteries don't behave exactly as this simple linear formula would indicate. Therefore, when amp-hour capacity is given for a battery, it is specified at either a given current, given time, or assumed to be rated for a time period of 8 hours (if no limiting factor is given).For example, an average automotive battery might have a capacity of about 70 amp-hours, specified at a current of 3.5 amps. This means that the amount of time this battery could continuously supply a current of 3.5 amps to a load would be 20 hours (70 amp-hours / 3.5 amps). But let's suppose that a lower-resistance load were connected to that battery, drawing 70 amps continuously. Our amp-hour equation tells us that the battery should hold out for exactly 1 hour (70 amp-hours / 70 amps), but this might not be true in real life. With higher currents, the battery will dissipate more heat across its internal resistance, which has the effect of altering the chemical reactions taking place within. Chances are, the battery would fully discharge some time before the calculated time of 1 hour under this greater load.We bought it for our medical otoscope when the original died. Works just fine. You have to buy the correct battery for the tool you are using. This was manufacturers choice, we replaced it with the same battery. Designed to work with that specific product..
