Sears 44080 Battery Replacement - Motobatt MB5U Sealed AGM

A Sears 44080 battery replacement for a bike coming back after years off the road. The 44080 is a 12N5-4B size. We've dropped the flooded 12N5-4B this page once sold. Motobatt's MB5U replaces it: sealed AGM, the same case, a higher price. Cheaper flooded batteries still work for owners who top up the water. With a long list ahead of the bike, the battery can be the easy part.

Warranty

Warranty. If your MB5U fails in its first year, counted from delivery, we replace it at no cost.

When the Bike Has Sat for Years

The old battery has had its day
Years parked usually means years flat, and few batteries come back from that. Save your patience for the fuel system and tires.
One less job on the list
On a revival, every job seems to turn up two more. The MB5U arrives factory activated with nothing to add, so it goes from the carton into the tray and comes off the list that day.
Charge to spare while you sort it out
A bike coming back gets tested over and over: lights, horn, key on, key off. With 7Ah where our flooded 12N5-4B had 5Ah, the MB5U lasts longer between charges.

Long storage often leaves white or green crust on the tray and cable ends. Work it off with a baking soda paste and let everything dry before the MB5U goes in.

  • Fits where the 44080 came out - same case size, and four Quadflex posts that suit 4B or 3B wiring. We tested both on an MB5U.
  • Ready for the old leads - brackets and screws for the terminals, with a hex key to tighten them.

Frequently Asked Questions

What size is a Sears 44080 battery?

A 12N5-4B, the 12-volt size that measures 120 x 60 x 130 mm. The MB5U shares that case, and its posts suit 12N5-4B leads.

The bike sat for years. Is it worth trying to revive the old battery?

Rarely. Sulfate hardens on the plates the longer a battery sits flat. A charger may bring the voltage back while the battery still fails under load. If it lived on a maintainer, charge it and have it load tested. If it sat flat, replace it.

Does Sears sell this battery?

No. Motobatt manufactures the MB5U, and High-Tech Battery Solutions is the store selling it. The 44080 number is here because it may be what's printed on the battery you're pulling.

Pulling a bike out of storage?

Read us whatever's left on the old 44080's label, and we'll check it against the MB5U.
