What are important when you buy batteries?

A Size

CR1225 is a small cell battery shaped like a made of Lithium material with 3V high density and high volt of power. cells are very very small and looks very similar. Choose the correct size is the most important. Since the digit numbers indicates the battery size, make sure the four digits are the same as the original numbers.like CR1225 is 12*2.5mm,CR2032 is 20*3.2mm.

B Safety

Lithium cells are with 3V high voltage with high capacity even though they are small.

Batteries from trustful big brand states brand name on the package and on the battery cell. Make sure you are buying good quality batteries from trustful brand or big factory. Batteries without brand name on the cell may be from small factory and made by poor technology. It may cause battery leakage or explosion which is quite dangerous for your family safety.

C Stability

Different technology, different stability. Stability is related to cell material,shell material and technology.Many ordinary brands use iron or stainless steel shell, while name brands use nickel plated shell. With nickel plated shell, which is a kind of rare metal with ultra high precision and higher cost, batteries can achieve up to 5 years shelf life without leakage because they are sealed much better and are more steady.

D Durability

Good batteries should last as long as possible. Nobody wants to change batteries quite often.

Durability is related to capacity. Good factory or brand marks capacity on the card package or in the description. The higher capacity, the longer durability. Capacity is marked as XXXmAh. Some doesn’t show capacity, some puts fake capacity, make your eyes open.

E Freshness

3V Lithium batteries are single use batteries. Good factory or brand clearly marks manufacture date on batteries so as to follow up ,control and improve quality. Many of brands on the market does not mark MFG date, or only has expiration date, consumers are not sure when the batteries were made and may buy old batteries. Old stock batteries may have very low power. Check whether the batteries have manufacture date and know how new they are to avoid old batteries.

F Mercury free

Good manufacturer pay high cost to use mercury free material to protect our earth.
