Purchasing Mobile/SmartPhone Battery
Mobile/SmartPhone Battery by iTEKcanada.com are usually lower in price and usually exceed the performance of OEM Mobile/SmartPhone Battery. Many of iTEKcanada.com’s Mobile/SmartPhone Battery use the same battery cells as OEM batteries.

What is mAh / Wh?
These ratings show battery`s capacity. Think of them as gas in your car tank, the bigger the tank, the more fuel it will carry and your car will drive longer. Same with these batteries, the higher the mAh/Wh, the longer your device will run between recharges.

Will your higher capacity (mAh/Wh) Mobile/SmartPhone Battery work in my device, even though my original battery has a smaller rating?
Definitely! Our batteries are designed to be 100% replacements for original batteries. Higher mAh/Wh rating means longer run time between recharges. The higher the rating the slower it will take for the batteries to drain down. Meaning you will get longer talk time with a higher mAh rating. In other word, higher is the mAh number, better it’ll be for your device.

Quality and Safety
This battery contains advanced technical components and has been tested according to strict CE safety standards. The battery contains a chip that prevents overcharging and short circuiting. Next to this the battery is made from high quality cells that do not suffer from a so-called 'memory effect'.'

Factory Fresh
Batteries lose performance over their lifetime, even when they are not used. Many importers and resellers store their batteries in stock for a long time before they are sold. iTEKcanada.com sends products almost directly from the factory, so you are sure that you will get a brand new high quality battery!

Stunning Gentleman's Watch
Color: Grey
This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.

Good Tissot Watch
Color: Grey
Arrived on time, in its original box, include a 2 year international warranty, into the box include a book with the Tissot brand history in Switzerland. Algo a second book with a whole catalog of Tissot watches men and women. The watch looks better when you put in on your wrist. The “naval” blue really gives the clock a classy look. The stainless steel workmanship is really good, the metal is bright and perfectly polished. The metal wristband quality is very good, did not have any problem to adjust the size , I went to my preferred clock workshop for this job, they extracted a few pieces of the band to fit to my small wrist size. Have to get used to the butterfly latch, but after a few days, now I learned to open and close it without any effort. The clock it’s very accurate, I’ve been using my Tissot for near a month and it just increased a few seconds per week. I do the setup and check accuracy with my pc clock. In short, It”s a good value watch, nice, good looking, accurate.

Great Buy

Stunning watch!! Purchased for my boyfriend for his birthday. He is a bigger guy with a larger arm/wrist so the size of this watch looks great on him. He receives a ton of compliments on it, and it still catches my eye every time he wears it. Decent weight without being too heavy (he reports). Perfect to wear as a daily watch or dress up with
