- Weight: Deka batteries are generally lighter than traditional lead-acid batteries. This made handling and installation much easier for me.
- Terminal Placement: I made sure to check the terminal placement on my new battery. It’s essential to ensure that the positive and negative terminals are in the same position as the old battery for a hassle-free installation.
