BATTERY

DIFFERENCE between non-rechargeable and rechargeable battery:

• Non rechargeable batteries are called primary batteries, while rechargeable batteries are called secondary batteries

• A chemical reaction goes inside non rechargeable batteries’ that release electricity needed to run appliances

• The chemical reaction can be reversed to send or rush electricity inside rechargeable batteries to charge them

• Non rechargeable batteries are cheaper than rechargeable batteries that however prove to be more cost effective because of their ability to be recharged hundreds of times.

Types of popular rechargeables:

NiCad (Nickel Cadmium)- Cheapest and if not properly maintained will get a memory drastically reducing their battery life (drain quicker). Not for use in high drain devices like cameras - unless you like to pack lots of batteries.

NiMH (Nickel Metal Hydride) - Long life, middle cost, no memory - need special chargers - smart or passive. Good for high drain devices

Lion (Lithium Ion) - More specialized batteries. Last a really long time. Most expensive in most cases. Good for high drain devices. Usually require smart chargers.

p/s: i prefer NiMH because the current are higher compare to other rechargeable battery.
