Questions and answers
Is gel the same as the battery I have now?
Most smart chargers have a mode for gel. Select it before charging; an unsuitable programme can shorten battery life.
What family does this battery come from?
It belongs to the MK GEL line from MK Battery. Other models in the same line share the construction and differ mainly in size and capacity.
How can I be sure the MK Battery 8G30H is compatible?
The safest test is a direct comparison: same voltage, same or slightly higher capacity, same case size and the same terminal orientation. Your owner's manual usually lists the original values.
Quick compatibility checklist
- ✓ Measure the space available: the case takes up 328.4 × 171.2 × 247.7 mm, and a few millimetres too many can stop the hold-down from closing.
- ✓ Capacity is 97.6Ah. Aim for the same figure as your old battery or slightly above, never much lower.
- ✓ Sticking with gel avoids surprises, unless your vehicle maker approves a change.
