Speaker battery replacement.

I have a bluetooth speaker and the battery is dead.

Its 12V and 4Ah.

Can i replace it with a 12V 7Ah motorbike battery since i live in a place where its hard to find batterys

Yes, as long as the voltage is correct.

And battery type. Lead-acid, NiMH or Li-ion can't be charged using same charging unit. If it was using NiMH, then you need to get NiMH. If it was Li-ion, you'll have to take Li-ion.

Also, motorcycle battery is not the right type of lead acid battery.

Those are "optimized" for high current bursts, what happens when you hit the ignition ... they're not designed for continuous slow discharge (what happens when you listen to music)

If the speakers do use lead acid battery, then you should look for a UPS battery, a VRLA battery (no maintenance) ..

 

for example 12v 8Ah battery : https://www.newegg.com/cyberpower-rb1280-battery-unit/p/N82E16842102171

or 12v 3.5Ah battery : https://www.newegg.com/rbc35-sla35-bti-battery/p/N82E16842109062

12v 7Ah are also very common : https://www.newegg.com/ereplacements-ub1270-er-battery/p/N82E16842212002  or https://www.newegg.com/apc-rbc40-battery/p/N82E16842101229?Item=N82E16842101229
