How many volts are in a battery?

Most household batteries range from 800 to 2,500 mAh. Higher-capacity batteries are becoming available. Most household batteries have 1.2 volts. Some specialty batteries (like CR123A batteries) use higher voltages, though. You’ll need to ensure that the voltage of your batteries matches the device requirements.

Do you need a lithium battery for disaster preparedness?

For disaster preparedness, you’ll need to stockpile NiMH LSD and non-rechargeable lithium batteries. NiMH LSD batteries can hold 70-80% of their charge for up to 10 years in storage, so they will be ready to use when you need them. Some can be recharged 2,000+ times.

What kind of batteries do you use for critical gear?

Whenever possible, choose gear that uses the same size of batteries. For example, my headlamps, UV water filter, and emergency radio all use AAA batteries. If one piece of critical gear dies and I can’t recharge, I can take the batteries from another device to use.

What are the different types of batteries?

Batteries are named by the type of chemistry used in them. The chemistry matters greatly! It affects everything from capacity, performance, lifespan, and shelf life. The main battery options are alkaline, Ni-Cad, NiMH, lithium, and li-ion. Alkaline batteries used to be the only choice for household batteries.

Should I add a full battery with a half-charged battery?

Adding a full battery with a half-charged battery will not help the device run at a higher capacity. Even good rechargeable batteries are susceptible to overheating and overcharge. Unfortunately, almost all rechargeables come with really cheap chargers.

Are lithium batteries good for backpacking?

The weight-to-capacity ratio is also fantastic, which makes them great for situations like backpacking or bug out bags where you want to keep weight down. The quality of lithium batteries is generally very high, so you can get a lot longer running life out of the batteries compared to other types like NiMH LSDs.
