Li-on AAA Rechargeable Battery
1) I’m planning to buy an ‘entitled’ item for a stopwatch and a timer I wish to buy, would it be a good decision?

2) What is the highest mAh available an what is the Voltage (V)?

3) What will I need for this?

 * Gymboss says "We recommend a high quality Energizer or Duracell" - so they're not recommending rechargeable batteries. The Amazon page for it says it takes a single AAA. -- Finlay McWalter··–·Talk 12:13, 10 December 2016 (UTC)


 * What do you suggest I buy? A rechargeable AAA battery? If so, what Voltage Li-on "mAh" high power could it be? 103.230.104.11 (talk) 18:44, 11 December 2016 (UTC)


 * I suggest you follow the manufacturer's instructions. The voltage drop curves for alkaline and rechargeable batteries are quite different - some devices tolerate this well, some don't. If you're using this device as it seems to be intended (to allow you to lead a interval class for tens of people) the cost of ruining the class for all those people (when the device stops working, because you used a battery different to the manufacturer's suggestion) is surely much more than the cost of a single cheap alkaline AAA battery. -- Finlay McWalter··–·Talk 22:26, 11 December 2016 (UTC)
