Delivered By

?
  • Usually Delivered in 6-7 business days.

What is the estimated delivery time?

Sellers generally procure and ship the items within the time specified on the product page. Business days exclude public holidays and Sundays.
Estimated delivery time depends on the following factors:
  • The Seller offering the product
  • Product's availability with the Seller
  • The destination to which you want the order shipped to and the Seller's location

Why does the delivery date not correspond to the delivery timeline of X-Y business days?

It is possible that the Seller or our courier partners observe a holiday between the day you placed your order and the date of delivery, which is based on the timelines shown on the product page. In this case, we add a day to the estimated date. Some courier partners and Sellers do not work on Sundays and this is factored in to the delivery dates.

Best Rechargeable Battery I have Ever Bought!!!

Photography is my hobby. Now I'm 23, I'm Taking photos from the age of 10. Why I'm saying this is I've bought a lot of rechargeable batteries during this period.

Common issues faced in Rechargeable batteries
1. Capacity --> you should buy above 2000mah - which is available in common nowadays.
2. Another issue is the free drain time.
You may be aware of this. so let me explain it. Recently I have bought some Sony and Hybrio batteries. (sony 2500mah, hybrio 1800mah)

Test 1: (continuously taking photos with flash enabled)

sony - 1055 photos taken
hybrio - 849 phot

A good product

I already owned a set of Sony rechargeable batteries and another similar set of batteries from a different company. Sony batteries outlasted the other brand's batteries.
I needed another set of batteries for my camera and so I went for this one.

Unlike my old set of batteries, these batteries do stay charged even when unused for long periods of time ... didn't really test for the 1 year claim .. but I have used them over intervals of 2-3 months with satisfactory performance.

So far did not face any issues.

Good performance & service

Purchased this for use in toys for my daughter. Very good performance. Mostly used in a remote controlled car and once charged can be used for many days. Since batteries are pre-charged, it can be used right out of the box.

Rechargable batteries

These are the best rechargable batteries that I have used for almost all of my electronic gadgets which include cordless mouse, cordless keyboard and also my camera. They have given me the best battery life per charge when compared to other brands available in the market.
