upgrading from 12V 12Ah to 14Ah Lead Acid

Hello, i have a Mowbot lawn mower which uses two 12Volt 12Ah lead acid batteries to power it.

Can i replace these for 14Ah batteries to improve the performance time or will there be charging complications ?

Many thanks

The 14Ah are probably newer versions of the 12Ah. Should work fine.

It may just take a little longer to achieve full charge.
