You have a couple mistakes in your updates. I think generally you're confusing the value of the current weights with the difference between the current weights and the previous weights. You have $\Delta$ symbols scattered around where there shouldn't be any, and += where you should have =.
Perceptron:
$\pmb{w}^{(t+1)} = \pmb{w}^{(t)} + \eta_t (y^{(i)} - \hat{y}^{(i)}) \pmb{x}^{(i)}$,
where $\hat{y}^{(i)} = \text{sign} ({\pmb{w}^\top\pmb{x}^{(i)}})$ is the model's prediction on the $i^{th}$ training example.
This can be viewed as a stochastic subgradient descent method on the following "perceptron loss" function*:
Perceptron loss:
$L_{\pmb{w}}(y^{(i)}) = \max(0, -y^{(i)} \pmb{w}^\top\pmb{x}^{(i)})$.
$\partial L_{\pmb{w}}(y^{(i)}) = \begin{array}{rl}
\{ 0 \}, & \text{ if } y^{(i)} \pmb{w}^\top\pmb{x}^{(i)} > 0 \\
\{ -y^{(i)} \pmb{x}^{(i)} \}, & \text{ if } y^{(i)} \pmb{w}^\top\pmb{x}^{(i)} < 0 \\
[-1, 0] \times y^{(i)} \pmb{x}^{(i)}, & \text{ if } \pmb{w}^\top\pmb{x}^{(i)} = 0 \\
\end{array}$.
Since perceptron already is a form of SGD, I'm not sure why the SGD update should be different than the perceptron update. The way you've written the SGD step, with non-thresholded values, you suffer a loss if you predict an answer too correctly. That's bad.
Your batch gradient step is wrong because you're using "+=" when you should be using "=". The current weights are added for each training instance. In other words, the way you've written it,
$\pmb{w}^{(t+1)} = \pmb{w}^{(t)} + \sum_{i=1}^n \{\pmb{w}^{(t)} - \eta_t \partial L_{\pmb{w}^{(t)}}(y^{(i)}) \}$.
What it should be is:
$\pmb{w}^{(t+1)} = \pmb{w}^{(t)} - \eta_t \sum_{i=1}^n {\partial L_{\pmb{w}^{(t)}}(y^{(i)}) }$.
Also, in order for the algorithm to converge on every and any data set, you should decrease your learning rate on a schedule, like $\eta_t = \frac{\eta_0}{\sqrt{t}}$.
* The perceptron algorithm is not exactly the same as SSGD on the perceptron loss. Usually in SSGD, in the case of a tie ($\pmb{w}^\top\pmb{x}^{(i)} = 0$), $\partial L= [-1, 0] \times y^{(i)} \pmb{x}^{(i)}$, so $\pmb{0} \in \partial L$, so you would be allowed to not take a step. Accordingly, perceptron loss can be minimized at $\pmb{w} = \pmb{0}$, which is useless. But in the perceptron algorithm, you are required to break ties, and use the subgradient direction $-y^{(i)} \pmb{x}^{(i)} \in \partial L$ if you choose the wrong answer.
So they're not exactly the same, but if you work from the assumption that the perceptron algorithm is SGD for some loss function, and reverse engineer the loss function, perceptron loss is what you end up with.
