--Whenever I cannot find specialty batteries in our local area Battery Upgrade is the only place I have been able to find them.
About the product:
-I could not find the batteries I needed from any other source, on line or local area store...even the store that carried the phone I needed the battery for could not supply it. Battery upgrade was the only source available and they delivered in a timely manor.

About the product:
It was a battery for an older cordless phone. The special phone is used with hearing aids. My 99 year old grandmother has not had any issues with the new battery. (Side note: In 4 weeks she will turn 100!)

Assurance and warranty
The BTC-AY4020CL battery (1200 mAh 3.7 V) comes with 12 months warranty. Besides this, we offer a unique 30-day money back guarantee: in case you are not satisfied with the product, for whatever the reason, you can always return it and get your money back.
Quality and safety
This BTC-AY4020CL battery (1200 mAh 3.7 V) contains advanced technical components and has been tested according to strict CE safety standards. The BTC-AY4020CL battery contains a chip that prevents overcharging and short-circuiting. Next to this, the BTC-AY4020CL battery is made from high quality cells that do not suffer from a so-called 'memory effect'.
Factory Fast
The BTC-AY4020CL battery is factory fast. 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. BatteryUpgrade.co.za makes sure that the ordered battery can be shipped directly after production by working together with the manufacturers. So you can be sure that you will get a brand new high quality battery!
