Purpose

The Tonkeeper Battery is an innovative off-chain account within the Tonkeeper wallet designed to solve the "gas problem." In the TON ecosystem, every action—from sending a token to swapping on a DEX—requires Toncoin (TON) to pay for network fees. If you receive an airdrop or USDT but have zero TON, you are effectively "stuck." The Battery serves as a prepaid power source that covers these fees on your behalf. In 2026, it has become the standard for gasless transactions, allowing users to interact with the blockchain using "charges" instead of managing raw gas balances.

Step-by-Step

1. Locate the Battery Menu

Open your Tonkeeper app and tap the Settings icon in the top right corner. Select Battery from the menu. Here, you will see your current charge level and history.

2. Choose Your Charging Method

You can "recharge" your battery in several ways depending on your available resources:

• In-App Purchase: Use your Apple Pay or Google Pay to buy a "Small," "Medium," or "Large" pack of charges directly with fiat currency.
• Stablecoins/Tokens: If you have USDT, NOT, or other supported Jettons but no TON, you can use these tokens to "buy" battery charges within the app.
• Direct Deposit: Send supported tokens to the special address battery.ton from your wallet to automatically top up your balance.

3. Wait for the Virtual Credit

Once the payment is confirmed, your Battery balance will reflect in "charges." Unlike Toncoin, these charges are denominated in units that represent specific actions (e.g., 1 charge = 1 simple transfer).

4. Execute a Gasless Transaction

Simply perform a transaction as usual (e.g., Send USDT or Swap CATI). Tonkeeper will automatically detect that you have Battery charges. It will prompt you to confirm the transaction, using your Battery to cover the network fee instead of deducting Toncoin from your main balance.

Use Case

The Airdrop Participant:

A user receives 10,000 HMSTR tokens from a Telegram game airdrop. They have 0.00 TON in their wallet. Ordinarily, they would have to buy TON from an exchange and send it to their wallet just to move their tokens. With Battery, they can charge it using a $3 in-app purchase and instantly swap or send their airdrop tokens without ever touching an exchange.

The NFT Collector:

A user wants to gift an NFT to a friend. Instead of calculating complex gas fees, they know that an NFT transfer costs exactly 10 charges. They keep their battery topped up to ensure they can always manage their collectibles with one-tap convenience.

Best Results

For the best results in 2026, pay attention to the Charge Cost Table. While a simple TON transfer might only cost 1 charge, a complex decentralized exchange (DEX) swap may require 50 to 90 charges due to the underlying smart contract complexity. If you frequently trade, the "Large Pack" via in-app purchase offers the best value per charge. Additionally, ensure you are using the W5 Wallet Standard within Tonkeeper; this newer architecture is optimized for the Battery and reduces the "delay" sometimes seen when the relay service broadcasts your transaction.

FAQ

Can I use the Battery to send Toncoin (TON) itself?

No. The Battery is specifically designed to help you interact with the network when you don't have TON. If you are sending TON, the network naturally deducts the fee from the amount being sent.

Do Battery charges expire?

In 2026, Tonkeeper Battery charges do not have an expiration date. Once purchased, they remain in your off-chain account until consumed by transactions.

Is the Battery feature custodial?

The Battery balance itself is managed by Tonkeeper’s relay service (off-chain), but your actual tokens and NFTs remain in your non-custodial wallet. The Battery only "pays" the fee; it never has access to your private keys.

Disclaimer

The Tonkeeper Battery is a service provided by Ton Apps Group. While it simplifies fee management, the cost of "charges" may include a small service premium compared to paying native gas fees directly with Toncoin. The availability of specific token-to-battery swaps depends on market liquidity and current relay service support. This tutorial is based on the 2026 version of Tonkeeper (v5.x and above).
