Energizer 02055810 Battery Replacement - Motobatt MB5U Sealed AGM

An Energizer 02055810 battery replacement for a motorcycle parked in the garage you walk through every day. That Energizer number is a 12N5-4B size. The flooded battery we sold under it ran on free liquid acid and used a vent tube, and we've dropped it. Motobatt's MB5U takes its place: sealed AGM, in a case of identical size. It costs more, and you see why on ordinary days at the workbench.

Warranty

Warranty. High-Tech Battery Solutions covers the MB5U for one year of free replacement, starting the day you take delivery.

Living With It in the Garage

Sealed lid, no tube to run
A flooded battery has filler caps and a vent tube routed down under the bike. The MB5U's lid is sealed: no caps to pull, nothing to route.
No acid loose in the case
Glass mat absorbs the acid, leaving no free liquid, and Motobatt marks the case non-spillable. Shelved for winter, it has nothing to seep onto what's below.
No distilled water jug on the shelf
Per its label, it never needs water. The jug and funnel can leave with the old battery.

A flooded battery costs less and can serve in a detached shed where someone checks the levels. We no longer stock one. When the bike shares a wall with the house, sealed AGM with no free acid is worth the extra money.

  • Either terminal arrangement covered - Quadflex posts, a pair per polarity. We confirmed on a unit that 4B or 3B leads each reach a matching post.
  • Bracket set and hex key packed in - plus the screws they need.

Frequently Asked Questions

What does Energizer 02055810 cross to?

A 12N5-4B, which lookups may show as 12N54B or 12N5 4B. The MB5U fits that case, and its four posts take 12N5-3B leads as well.

Is a sealed battery safer to keep in an attached garage?

It leaves out two things a flooded battery brings: free liquid acid that can spill, and an open vent tube. It's still a battery, so cover the terminals and keep metal tools off them; a wrench that lands across positive and negative can short it. Charge it in a ventilated spot, such as with the garage door up.

Is this an Energizer battery?

No. It's a Motobatt battery, and the label says so. It replaces the Energizer 02055810 by size and terminal fit, not by brand.

Have the old Energizer in front of you?
