Canada Post and the Canadian Union of Postal Workers (CUPW) have reached agreements in principle and are now working to finalize the details. While this process continues, all strike and lockout activity has been suspended, and mail operations are running.
At this time, Canada Post has not released details about the agreements, but they will continue to provide updates as the situation progresses.
We will keep our customers informed of any changes that may affect shipping.
It’s super simple! Just add the product you want to your cart, enter the quantity and your postal code, and you'll instantly see real-time shipping rates for all in-stock items. Fast, easy, and totally hassle-free!
If your order includes multiple heavy products, we recommend requesting a custom quote — we may be able to arrange a better rate with a transport truck!
Please note: We reserve the right to send heavier items by transport truck if the carrier's maximum weight per package is exceeded or if we consider it too risky to place with a courier due to the possibility of damage occurring.

Rechargeable Lithium-Ion batteries from Cameron Sino Technologies have a limited lifespan and will gradually lose their ability to hold a charge. This natural process, known as aging, is irreversible. As the battery ages, its runtime—the amount of time it can power a device—will steadily decrease.
These batteries also self-discharge slowly when not in use or while in storage. To maintain performance, check the battery’s charge level regularly. Your device’s user manual should provide instructions for checking battery status and charging procedures. For the latest manuals, visit your product manufacturer’s website.
Important: Always use batteries recommended by Canadianbatteries.com for safe and reliable performance.
Follow the product-specific charging guidelines in your user manual. For dual battery setups, test one battery and slot at a time—one defective battery may prevent the other from charging.
Note: Batteries self-discharge in storage. High temperatures (above 20°C/68°F) can reduce battery life.

Some Useful Battery Information
Please read this before using your new battery!
Cordless phone batteries, Cell phones, PDAs, Power Tool Batteries, and all devices with the chemistries below
These types of batteries can be NIMH, NiCad, or Lithium Ion all these three chemistries have similar properties when looking after them.
Initial charge- all three types of batteries should be fully charged overnight on receipt.
Charges 2-6- it is very important to fully charge the battery on receipt and then use the battery until the device says low battery. There is no need to force a discharge just use the device as normal until the battery runs down to about 20% of its charge. The important thing about these 2-6 conditioning cycles is that you do not top up the battery until it reaches about 20% of its charge. Do not let the battery run flat, especially on the first 3-4 cycles.
After conditioning- the best course of action to lengthen the life of these types of batteries is to only replace the device on the charger when the device needs charging. All three chemistries of batteries can be cycled around 500 times if the device was placed on the charger once every day after one use the battery would last approx 500 days if placed on the charger twice a day after use the battery would last approx 250 days. A battery does not half cycle so even if the battery was 80% charged a full cycle will be used when it is placed on charge.
SLA Batteries
This type of chemistry does not need conditioning the battery can be cycled around 300-400 times, although the battery is best used heavily at the top end of its charge. This battery should be topped up and not used till flat.
The average life of an SLA battery is 2-3 years depending on use and care.
Laptop Batteries
Most laptop batteries today use Lithium Ion Technology. The recommended care is slightly different from that above.
Initial charge- The battery should be fully charged overnight on receipt.
Charges 2-6- it is very important to fully charge the battery and then use the battery until the device is discharged to only about 20% of its charge. Do not let the battery drain down completely or the charging circuit in the laptop may not detect a good battery. This is especially important in the first 5 cycles. There is no need to force a discharge just use the device as normal until the battery runs down. The important thing about these 2-6 conditioning cycles is that you do not top up the battery until it reaches 20% of its charge.
After conditioning- the best course of action to lengthen the life of these types of batteries is more difficult to ascertain the main problem is that if you are constantly plugging in and out of the mains adaptor the battery life will be reduced significantly. .The best thing to do is to make sure that you fully cycle the battery and let it run low at least once a month. Lithium batteries need to be exercised to maintain their usability.

All About Our Paid Shipping Services
Canadianbatteries.com offers a wide variety of shipping methods through Canada Post, FedEx, UPS, Canpar, and Purolator. It's up to you to select the method best suited to your time scale and budget. Some shipping methods are not available for certain products.
Shipping costs are automatically calculated by our intelligent shipping estimation program based on the weight, distance to the destination, and the shipping service. To obtain your shipping cost, add the desired items to your shopping cart, proceed to checkout, and enter your postal code. Here you will be shown the available shipping methods, expected transit times, and the estimated delivery date with pricing.
It's important to understand that in-transit times and delivery dates are the best estimates provided by the respective carriers. Once we hand off the package to the carriers, responsibility for carrier or weather-related delays is passed to them. Transit times should be calculated only on business days and do not include weekends and holidays. Depending on product availability, this may postpone the actual shipping dates.
We endeavor to ship most orders by the next business day, but certain products, including sealed lead acid, may take longer. If there is a delay longer than five days, we will notify you. We can only ship to PO Boxes with Canada Post; FedEx and all our other services cannot deliver to post office boxes. We will require at least one business day for order processing.
A confirmation email is sent to you once your order is placed. Please check that the address details provided in this email are correct within 30 minutes of placing the order and notify us of any errors. If no corrections are made within this time, we will consider your order placed with the correct address. Should an incorrect address be entered, and the shipment is returned by the carrier, the cost of the shipment and the return cost will be covered by you, the purchaser. These costs may be deducted from any refund if you cancel the order or choose to have it reshipped. This applies even if your order was placed via PayPal Express Checkout; it is your responsibility to confirm that the address is correct, including orders placed over the telephone.
We are based in Ontario, Canada. You can choose to see prices in Canadian Dollars or USD. Select your preferred currency; C$ is shown when CAD is selected. We hold a vast inventory of products, but some products with limited shelf life are held in smaller quantities. Occasionally, your order may overlap with stock rotation, which may delay your order. If this occurs, we will notify you immediately with the expected arrival date. If you can't wait, respond to the email, and we will refund your order and notify you when the new stock arrives.
To see your shipping charge, add the quantity of the product to your shopping cart, then enter your postal code on the next screen.
