At the Honda Service Centre I was told that it is time to change my battery on my scooter. I am using an AMCO APX4 on the scooter now. I was looking online for the best battery to replace it with and one suggestion was the Amaron Pro Bike Rider ABR-PR-12APBTX-50. I understand that this is a 5 amp battery. Will replacing a 4 amp with a 5 amp battery cause trouble. All that I know is that a 5 amp battery can last about 20% longer. Shall really appreciate your responses. Thanks.

  • Do you mean amp? or do you mean amp-hour? 4A or 5A is very low for battery supply. 5Ah is pretty low for a battery capacity but probably OK.

  • @Chenmunka - I'd suggest you're right, considering the OP states the new one will last 20% longer ... though in actuality if it is Ahr, wouldn't it be 25% longer? Commented Nov 6, 2017 at 14:08

    @Pᴀᴜʟsᴛᴇʀ2: That was my thinking. The OP does say about 20%. We can allow a margin of error - and most batteries are sold with Ah ratings, not A..

  • I'm curious even with OP's typo if a higher amp-rated battery would be safe to use as well. My instincts are that electrical components in the scooter would only "draw" as much amperage as they need and any extra output the battery can provide would be a safe overhead. But i'm not 100% certain. Commented Nov 6, 2017 at 19:58

The short answer to your question is, no, replacing a 5A battery with a 4A battery will not cause trouble as long as fitment and voltage are the same.

That said, automotive batteries are usually measured with two metrics Ah (Amp Hours) and CCA (Cold Cranking Amps), but not strictly amps.

Amp Hours refers to the charge the battery holds, and the measurement is relatively simple. a battery with 5Ah can sustain a 1 amp draw for up to 5 hours with a full charge. The actual life of the battery will vary with time.

Cold Cranking Amps is a measurement of surge current. How much current can the battery provide at one time without being damaged or worse.

In either case, bigger is fine. a 5Ah battery will last longer on a charge and a a 5 CCA battery will be able to provide a larger surge if required. The battery will only provide the current demanded by the load.


As long as the battery is the same voltage and has at least the same amp-hour rating (or better) as the old one, it should be good to use (presuming correct fitment, of course).
