Sealed, maintenance-free gel batteries built for real riding. BikeMaster’s TruGel line uses a gel electrolyte that resists vibration, won’t spill, and holds charge longer in storage than conventional flooded batteries — a practical choice for bikes that see seasonality, off-road use, or heavy vibration.
Quick Variant Specs
MG4L-BS — common small-bike / scooter group. Confirm exact dimensions for fit.
MG5L-BS — 12V · ~5 Ah · typical dims 114 × 71 × 106 mm (height incl. terminals). Confirm CCA/fit for your model.
MG7Z-S — mid small-bike group; vendor dimensions vary by listing — confirm before purchase.
MG9-BS — common compact 9 Ah size; typical dims ~151 × 87 × 105 mm.
MG20L-BS — larger capacity group; vendor dims ~175 × 87 × 155 mm; listed CCA values vary by source — confirm exact CCA for your application.
Always match group number, terminal orientation and physical dimensions to your bike before ordering.
Compatibility
Match the battery group (MG model / OEM group equivalent), terminal polarity, and clamp style — not just amp-hours.
Physical clearance and terminal reach are the usual failure points. If the battery sits tight or the cables don’t reach, it won’t matter what the Ah rating says.
Use your service manual or the WyldPerformance fit tool to confirm the correct MG model for your make, model and year.
Installation
TruGel units are sealed — no topping up. Install like any sealed battery.
Connect positive first, then negative when installing. Remove negative first when removing. Torque terminals to your OEM spec.
Secure the battery firmly. Vibration shortens life more than anything else.
For long storage, use a smart maintainer with a gel/AGM profile and top up if resting voltage drops under ~12.6 V.
Who This Is For
Riders replacing old, leaking or maintenance-heavy flooded batteries.
Owners who store bikes seasonally and want reduced sulfation risk.
Scooters, dual-sports, cruisers and ATVs that need sealed, vibration-resistant starting power.
DIY mechanics who prefer a sealed, ready-to-fit battery with proven vendor coverage.
Key Benefit
Reliable, sealed starting power that tolerates vibration and storage better than conventional wet cells. Pick the MG model that matches your bike and you get maintenance-free service and less fuss between rides.
FAQs
Are TruGel batteries ready to install out of the box?They ship charged, but check voltage. If the voltage is low after shipping or storage, give a slow charge before installing.Can I swap my flooded battery for a TruGel?Yes — only if the MG group, terminal layout and hold-down match. Confirm dimensions and polarity first.Do I need a special charger?Use a smart charger or maintainer. Chargers with a gel/AGM mode are recommended for long life.Will the battery leak if mounted on an angle?No. The gel electrolyte is spill-proof. Still secure the battery properly to avoid vibration damage.Which MG model fits my bike?Match the OEM group number or dimensions. If you tell me your bike make/model/year I’ll confirm the right MG variant.How long will this last compared to a wet battery?TruGel batteries resist sulfation and vibration better, which generally improves shelf and service life
