Title: Battery replacement for BMWKRT100
Post by: pinhead on March 10, 2022, 06:12:57 PM

I need to replace battery on my brick.  Any ideas for good ones?  I had a Duralast battery from autozone and it lasted 6 years.  $150 now to replace.

Odyssey PC 680s are good but pricey now.

I buy Westco's for my Ks these days. Not currently available at Amazon (where I usually get them) but Sierra BMW has a decent price:

I bought another AGM battery from autozone, ETX30.  The old one lasted 6 years without any issues so I went with that again.  Was $144 with exchange.

I had Wesco before I started using PC680's, but with the price difference I'll go back to Wesco, they were good batteries.
