I recommend a AGM (Advanced Glass Matt) Battery. It is better than a Gel Cell and it won't crack and cause problems when it get hot, like the Gel Cell. The AGM is the newest thing on the market that replaces the Gel Cell. The model # is YTX20H-BI, made by Interstate batteries. This battery has a 310amp Cold Cranking power, that is the highest available. It won't let you down, when you need starting power. This battery retails for $87.95.
