Looking for new battery for my 2014 Mazda 3

[kaboose]

Hi everyone
I purchased this vehicle 9 years ago and it has about 105k kms and I haven't changed the battery since I bought it brand new. However battery has been dying often as I need to frequently boost it so I am in a market for a new battery so other than Costco where else can I find a good deal on batteries? Also is this a good Costco battery? https://imgur.com/a/WlOLwln (this is the only one on Costco website)

Lastly how often do you guys change the battery on your car? I am surprised how I got 9 years out of this battery? (may be because I have low kms?)
Look for some genuine feedback
Thanks

The Costco kirkland generally get favourable reviews. Other options are the Canadian Tire Motomaster. Being in Edmonton, you may want to consider a deep cycle to help with cold starts.
