DRAG SPECIALTIES Battery Charger/Maintainer - Optimate 5 TM231V2

Modern motorcycles and powersports vehicles drain batteries even when parked—especially models with always-on electronics and security systems. The OptiMate 5 keeps your battery at peak charge year-round while preventing sulfation damage that kills batteries prematurely. This is essential maintenance equipment if you're storing a bike seasonally or want to extend battery life beyond typical replacement cycles.

Unlike basic trickle chargers, the OptiMate 5 uses a multi-step charging algorithm that safely recovers deeply discharged batteries (as low as 0.5V) and actively desulfates batteries below 4V—rescuing units most chargers won't touch. The 4-amp output handles larger AGM batteries in big V-twins without overcharging, while the weatherproof leads and handlebar hook mount permanently for year-round convenience.
