+    # APIs are implemented.
+    ```
+
+1. Implementing health HAL in recovery. The health HAL is used for battery
+status checks during OTA for non-A/B devices. If the health HAL is not
+implemented in recovery, `is_battery_ok()` will always return `true`.
+
+    1. If the device does not have a vendor-specific `libhealthd`, nothing needs to
+    be done. A "backup" implementation is provided in
+    `android.hardware.health@2.0-impl-default`, which is always installed to recovery
+    image by default.
+
+    1. If the device does have a vendor-specific `libhealthd`, implement the following
+    module and include it in `PRODUCT_PACKAGES` (replace `<device>` with appropriate
+    strings):
+
+    ```bp
+    // Android.bp
+    cc_library_shared {
+        name: "android.hardware.health@2.0-impl-<device>",
+        recovery_available: true,
+        relative_install_path: "hw",
+        static_libs: [
+            "android.hardware.health@2.0-impl",
+            "libhealthd.<device>"
+            // Include the following or implement device-specific storage APIs
+            "libhealthstoragedefault",
+        ],
+        srcs: [
+            "HealthImpl.cpp",
+        ],
+        overrides: [
+            "android.hardware.health@2.0-impl-default",
+        ],
+    }
+    ```
+
+    ```c++
+    // HealthImpl.cpp
+    #include <health2/Health.h>
+    #include <healthd/healthd.h>
+    using android::hardware::health::V2_0::IHealth;
+    using android::hardware::health::V2_0::implementation::Health;
+    extern "C" IHealth* HIDL_FETCH_IHealth(const char* name) {
+        const static std::string providedInstance{"default"};
+        if (providedInstance != name) return nullptr;
+        return Health::initInstance(&gHealthdConfig).get();
+    }
+    ```
+
+    ```mk
+    # device.mk
+    PRODUCT_PACKAGES += android.hardware.health@2.0-impl-<device>

 Default implementation for storage related APIs for (hwbinder) services of the
 health HAL. If an implementation of the health HAL do not wish to provide any
 storage info, include this library. Otherwise, it should implement the following
 two functions:

 void get_storage_info(std::vector<struct StorageInfo>& info) {
