NAPA 740-1883 Battery Replacement - Motobatt MB5U Sealed AGM
NAPA 740-1883 Battery Replacement - Motobatt MB5U Sealed AGM
Warranty
Reading the 740-1883 Number
A flooded 12N5-3B is cheaper, and it will serve a rider who checks the water level and tops it up. We no longer carry one. The MB5U is also rated higher, 90 CCA and 7Ah against 40 CCA and 5Ah: more current in cold weather and more reserve before it runs flat.
- Ready when it arrives - factory activated and sealed, with no initial charge needed.
- Post hardware in the carton - a hex key, plus the terminal brackets and their screws.

Frequently Asked Questions
What battery size is a NAPA 740-1883?
It's a 12N5-3B, a 12-volt motorcycle battery measuring 120 x 60 x 130 mm (4.72 x 2.36 x 5.12 in). The MB5U is the same size.
What's the difference between a 12N5-3B and a 12N5-4B?
Where the terminals sit. The case size is the same, but the posts are arranged differently. A two-post battery of the wrong type drops into the tray with its terminals in the wrong places for the bike's leads. The MB5U's four posts suit bikes set up for either. Put the bike's positive lead on a positive post and its negative lead on a negative one.
Is this a NAPA battery?
No. It's a Motobatt MB5U, sold by High-Tech Battery Solutions. The NAPA number is here because many buyers have it in hand, and it identifies what the MB5U replaces.
Give us the code printed on the case, whatever the brand, and we'll tell you if the MB5U matches it.
