Sure ; although it's less useful that what its description promises.

(defun yf/checktimer-after (timer)
  (when (eq battery-update-timer timer)
    (message "Ran battery update timer. current time: %s triggered-p: %s"
             (decode-time) (timer--triggered timer))))
(defun yf/checktimer-before (timer)
  (when (eq battery-update-timer timer)
    (message "Running battery update timer. current time: %s triggered-p: %s"
             (decode-time) (timer--triggered timer))))
(advice-add 'timer-event-handler :before 'yf/checktimer-before)
(advice-add 'timer-event-handler :after 'yf/checktimer-after)

(defun yf/checktimer-warn ()
  (when (timer--triggered battery-update-timer)
    (warn "battery-update-timer has trigger flag to t.")))
(add-hook 'post-command-hook 'yf/checktimer-warn)
