If you clearly known about addresses you need to check their balance, and not too vague like I have one wallet with some of addresses that have bitcoins, you can use Watch only wallets for checking its balance without need of opening a wallet with private keys.
Watch only wallets can eliminate risk of hacks on your wallet and bitcoin fund as hackers can not have access to Bitcoin private keys through watch only wallets so they can not steal your bitcoin.
