How to choose batteries

Ni-Alkaline, NiMH, NiCD, Alkaline, Heavy duty, Lithium

Characteristics of Ni-Alkaline Batteries

Ni-Alkaline is latest developed technology of NiMH batteries, which has extremely low self-discharge characteristics and standby for use over years after charge. It can completely replace Alkaline battery in all applications but with stronger power, more energy and recharge over 1000cycles.

Only AA and AAA currently available.

Cost a little high but hottest recently.

Voltage: 1.2V/cell

Characteristics of NiMH Batteries

NiMH is standard environmental friendly battery. It is rechargeable for 1000cycles. The standard battery need to charge before and standby for 3 months to 1 year.

There are all sizes available, F,D,C,SC,A,AA,B,N,AAA,4A,5A,9V

There are also different characteristic for choose, high power, high temperature, low temperature, standby charging, etc.

Voltage: 1.2V/cell

Characteristics of Ni-Cd Batteries

Ni-Cd batteries is going to be forbidden in Europe and most country. The Cadmium (Cd) is hazardous to human health. It is mostly replaced by NiMH batteries.

Price is a little lower than NiMH batteries in same capacity comparison.

Voltage: 1.2V/cell


Characteristics of Lithium Batteries

Lithium Batteries are high in energy density, but require PCB protection circuit for charging and discharging.  However, lithium batteries can catch fire  when improperly used, and single cell voltage is 3.7V 3 times higher than NiMH. Polymer is another option which can do better in safety concern.

Voltage: 3.7V/cell

Characteristics of Alkaline Batteries

Alkaline Batteries is primary battery and only use for 1 time. Mostly applied in standby power or simple electronic equipments.

Most common sizes: AA, AAA, C, D, 9V

Voltage: 1.5V/cell


Characteristics of Heavy Duty Batteries

Heavy Duty Batteries is primary battery and only use for 1 time. Mostly applied in standby power or simple electronic equipments. Capacity is lower than Alkaline batteries but energy is much lower. Mostly used in toys and gift items.

Voltage: 1.5V/cell

How to Choose batteries

1) Consumer application- Ni-Alkaline, NiMH, Alkaline and heavy duty

2) Industrial application- consult JeffPower

3) Sizes - F,D,C,AA,AAA,N,B,9V,SC etc

4) Cost - Cheap heavy duty and Alkaline

5) Endurance - Ni-Alkaline, NiMH, Lithium

6) Recycle or one time use - you decide.

7) Weight - Lithium

8) In case high quality lead-acid battery need to be used, NCSLA is absolutely the best choice.








NCSLA is improved version of SLA, which do not physically contain liquid electrolyte.

The structure of container for electrolyte is nano scale particles which is in-house development of Jeff Power Co. Ltd.

The micro structure of particles give excellent characteristics and performance of NCSLA, inluding :

High Temperature performance 65deg C

Low temperature performance -40deg C

Recovery from over discharge( 0 Volt )

5 times cycle life( Over 1000 cycles )

Resistance to Vibration

Safe to transport

High Power for Jump Starting
