Sup guys, I purchased a Braille 3121 battery 2 days ago, as I had long been using (see: shoving) an oversize battery since I installed my Magnus some time ago. Well I weighed my options as far as another battery source, and decided that I did not want to relocate my battery to the hatch. I figure cars that see street use often should not have a portion of their hatch compromised by an Optima or other huge ass battery.
So I began to look at different brands, to find something small enough to fit in the limited space left by the UICP. I considered the Odyssey PC680, but couldn't bring myself to trust a battery that small in all conditions. I looked at Hawker, Deka, the 51R series Optima, Kinetix, and finally Braille.
I obviously went with the Braille, as it offered twice the cold cranking amps at 0° F, then the PC680 or similarly sized rebadges. This battery offers 1380 cranking amps for the first five seconds, and over 1100 for 10 seconds, so on and so forth. It totally outclasses my old standard wet cell battery, despite it's small size. I searched extensively for reviews from people on various forums, and the consensus was that they all loved this battery. So I dropped the hammer. Let me say, this battery is light! You can place this battery wherever you need it with one hand. It is also compact, but not pocket sized like the PC680. It actually has the power the rival the Optima Red Top, despite it's size. It offers 75 minutes of reserve (15 mins less the the Red Top) and a 31 amp hour capacity. It offers 200 more pulse crank amps than the Red Top, and for it's size is quite the powerhouse. Finally, it is SMIM friendly, and comes with brass automotive terminals as well. Overall I am very satisfied with it.
