DYNAVOLT MG20HL-BS-C BATTERY 12V AGM FA Nano Gel 20Ah

The Dynavolt MG20HL-BS-C is a sealed, factory-activated AGM gel lead-acid motorcycle battery rated at 12 volts and 20Ah, with 450 cranking amps on tap for larger-capacity machines. It arrives charged and ready to fit, so there is no acid pack to handle and no filling or activation step before installation.

Because the electrolyte is held in a gel, the battery is non-spill and can be mounted in any position, making it a practical choice for cruisers, tourers, big-bore V-twins, ATVs and side-by-sides where battery trays sit at awkward angles. It is a direct upgrade or replacement for a number of common 20Ah cases, and uses a left-hand front negative terminal layout.

Suited to riders replacing a tired original battery or stepping up cranking performance on a bike that sits between rides.

Check the terminal voltage before fitting — if it reads below 12.6V, charge the battery on an AGM setting before installation for best service life.
The battery is sealed and factory activated; do not attempt to open the casing or add electrolyte.
Mount the battery securely in the tray so it cannot move or shift under vibration, even though it can be fitted in any orientation.
Observe the left-hand front negative (black) terminal layout when connecting; connect positive first and disconnect negative first.
Keep terminals clean and free of corrosion, and tighten terminal bolts firmly without over-torquing.
Use a charger with an AGM/gel-compatible setting — avoid high-current or unregulated chargers.
If the bike is stored or ridden infrequently, maintain the battery with a suitable trickle or maintenance charger to avoid deep discharge.
Store in a cool, dry place and recharge periodically if the battery is left out of the vehicle.
Dispose of the old battery through a lead-acid battery recycling point, not in general waste.
